Warehouse Activity Monitor - SAP WM

Use
The functions of the warehouse activity monitor are intended to assist warehouse administrators to oversee, plan and optimize work processes in the warehouse. It provides a means to notify responsible personnel in case there are delays or errors in the overall system. The warehouse activity monitor helps you to identify and correct warehousing errors or critical processes soon after they occur, thus enabling you to carry out warehousing transactions in a timely manner. The warehouse activity monitor provides

  • Automatic monitoring of warehousing processes
  • Automatic recognition and display of errors in the warehouse
  • Support in the analysis of processes in which errors have occurred
  • Support to error correction

Why do I need the warehouse activity monitor?
The warehouse monitor is useful for several reasons:

  • Not all warehousing processes are carried out in the system without errors.
  • Errors are often not recognized until sometime after they have occurred.
  • The search for the cause of an error and correcting it can be time consuming.

Orders to move stock in the warehouse should always be processed within a reasonable time period. One of the key features of the warehouse monitoring task is the checking of timely processing of transfer orders in WM. For example, if a pallet has not been moved from the goods receipt area to its destination within a few hours, then it is likely that the transfer order has been lost, misplaced or that an error has occurred.

Prerequisites
Whether or not a process or situation is considered to be critical depends upon the object that is to be monitored. You can use various criteria to decide whether a process is critical:

  1. As a general rule, you can say that a process is critical if the process has not been completed within an acceptable period of time.
  2. – For example, once the system creates a transfer order, it is expected that, as soon as the material in the has been physically moved to its destination in the warehouse, the transfer order will be confirmed.
    – When the system creates a posting change notice, soon afterwards, it is expected that the notice will be converted into transfer orders.

  3. For some activities in the warehouse, a deadline is set for the completion of the activity. This applies to
  4. – Supply of materials to production
    – Delivery processing

  5. For some situations in WM, a certain period of time or duration is considered to be acceptable. These situations can be viewed as critical if the expected time span is exceeded. Examples include:
  6. – Negative stock. As an example, negative stock is recorded in the goods receipt area if you post a goods receipt in WM before posting it in IM.
    – Stock in interim storage types. For example, when you post a goods receipt in IM, the system stores this information in the interim storage area for goods receipts.

Setting Time Parameters
You maintain critical time periods using the Customizing application. For most of the objects, you can define several critical time periods. For critical time periods, you define the time duration and a corresponding unit of time.

Additionally, you can define a time period with reference to a particular calendar. This ensures that days are excluded that are not to be calculated into the critical time period (such as weekends, holidays and so on).

All transfer orders that have been created but not confirmed within 4 hours are to be listed as critical transfer orders by the warehouse activity monitor. If the critical time period is defined with reference to the factory calendar, not all non-confirmed transfer orders that are created on Friday will be displayed on Monday morning as critical transfer orders.

When you define the critical time period, you need to ensure that only the exceptional situations are displayed by the warehouse activity monitor. This is important because of the additional time required to investigate and resolve a critical situation.

Features
In Warehouse Management, the warehouse activity monitor displays objects with critical processes. For each of the monitoring functions, the warehouse activity monitor offers additional functions that help you to analyze and correct errors. The additional functions that are available depend on the object concerned. The individual objects that you can manipulate.

Activities
You can control which of the monitoring functions the warehouse activity monitor can display for individual users or for user groups.

Unconfirmed Transfer Orders
Definition
When you display the critical processes for this object, the system lists all open transfer orders that were created but have not been confirmed within the time parameters defined in the system.

Use
The display of unconfirmed transfer orders is used to inform you in a timely manner whether transfer orders have not been confirmed or processed correctly. If desirable, you can then check these transfer orders. Since materials are not available in the system (or for shipment to customers) until the transfer order has been confirmed, it is important to identify unconfirmed transfer orders quickly.

Criteria
You can set the critical time period for the warehouse number and the movement type depending upon the business use of the transfer order. You can define several different critical time periods for replenishment or for transfer orders for a goods receipt. Additionally, you can define the critical time period depending upon the source and destination storage types of the transfer order.

Additional Functions
When you display a critical transfer order item, the system provides the following information in addition to the normal display data:

  • You can display the stock information in the source, destination and return storage bins of the transfer order item.
  • Any additional unconfirmed transfer orders with the same material number, batch, stock category, special stock indicator and special stock number, that access one of these bins, are noted by the warehouse activity monitor and can be displayed if necessary.

Using the warehouse activity monitor, you can carry out the following additional functions for transfer orders:

  • Confirm a transfer order in the foreground or in the background
  • Cancel a critical transfer order
  • Print a critical transfer order again
  • Block source, destination and return storage bins for a transfer order item
  • You can also unblock these bins. Blocking is meaningful if you need to check stock in a bin to clarify the critical status of a transfer order. This prevents the system from accessing a bin or from carrying out any processes that might change the stock situation in these bins.

Open Transfer Requirements
Definition
This object lists all transfer requirements which have not been fully processed within the time parameters defined in the system.

Use
This object is used to inform you in a timely manner, that

  • Goods have been received that have not yet been placed into stock.
  • A goods issue was posted in IM that has not yet been posted in WM.
  • Unprocessed replenishment requests for fixed bins exist.
  • The staging of materials for production was planned but has not yet taken place.

Criteria
When is a transfer requirement considered to be critical?
There are two criteria that determine whether an open transfer requirement is critical:

  • It has not been processed by the planned date and time defined in the transfer requirement.
  • The system has not set the status of the transfer requirement to processed within the time parameters defined in Customizing for the warehouse activity monitor.

Depending on the business use (the warehouse number and movement type) of the transfer requirement, you can decide which criteria is to be used by the warehouse activity monitor. You can also define the critical time period depending upon the warehouse number and movement type assigned to the transfer requirement. The first criterion should be used only if the planned date and time for the transfer requirement actually exist. Otherwise, you should use the second criterion.

Immediate Transfer Order Creation
An exception occurs when the system is setup for immediate transfer order creation. In this case, if the system fails to create the transfer order immediately, transfer requirements become critical soon after they are created because they do not have the status processed Since immediate TO creation for transfer requirements is controlled in the movement type, you can define a second critical time period in Customizing that is only valid for transfer requirements with immediate TO creation. If you do not define this critical time period the warehouse activity monitor uses the same criteria as for transfer requirements without immediate TO creation. If you have defined a special critical time period for transfer requirements with immediate TO creation, the system uses the second criterion.

Additional Functions
Using the warehouse activity monitor, you can carry out the following additional functions for transfer requirements:

  • You can create a transfer order for a transfer requirement in the foreground or in the background.
  • You can change the status of a transfer requirement item to processed.

Open Posting Change Notices
Definition
For this object, the warehouse activity monitor displays open posting change notices which have not been fully processed within the time parameters defined in the system. A posting change is not considered to be fully processed until the status of the posting change notice has been set to "U" (processed).

Use
The warehouse activity monitor informs warehouse administrators of posting change notices that were initiated in IM or WM that have not been processed in a timely manner.

Criteria
You can set the critical time period in Customizing for the warehouse number and the movement type depending upon the business use of the posting change. As with transfer requirements, there are posting change notices for which immediate transfer order creation is employed. As with transfer requirements, you can define a second critical time period that is only valid for posting change notices with immediate TO creation. If you do not define this critical time period, the warehouse activity monitor uses the same criteria as for posting changes without immediate TO creation.

Open Deliveries
Definition
For this object, the warehouse activity monitor displays all WM-relevant deliveries for which not all items have been picked that meet one of the following conditions:

  • The time requirements for staging were not met.
  • The time deadline for loading the delivery was not met.
  • The time period for the goods issue for the delivery was exceeded.

Use
This task is used to inform warehouse administrators in a timely manner whether deliveries have been processed on schedule. This makes it possible for you to take necessary measures to ensure on-time deliveries. This task also displays deliveries that may have been overlooked.

Criteria
Which of the three conditions above are used to determine whether a delivery is critical or not depends on the comparison time you define for creating the picking wave in Customizing. If you do not define a comparison time, the warehouse activity monitor uses the loading time as a reference for the critical time period. The critical time period should be defined so that sufficient time remains to take any corrective measures necessary to ensure that goods can be delivered on schedule.

For deliveries that contain both items that are picked from a WM-managed storage location as well as those that are not WM-relevant, you need to ensure that the warehouse activity monitor decides whether a delivery is critical or not exclusively from the standpoint of WM. This means that a delivery is not seen as critical if all WM-relevant items have been picked even though non-WM-relevant items exist that have not been picked within the specified time period.

A special case exists if the system selects the material staging time as the reference time because the system enters this time in both the delivery header and in the delivery item. These time periods can vary. Since the warehouse activity monitor only processes data at the header level, only the material staging time period in the delivery header is considered when calculating the critical time period.

Additional Functions
Using the warehouse activity monitor, you can carry out the following additional functions for deliveries: You can create a transfer order for a critical delivery in the foreground or in the background.

Critical Stock
Definition
With this task, the warehouse activity monitor can display

  • stock in an interim storage area
  • negative stock

Use
The display of critical stock in interim storage areas makes it possible for you to identify goods movements that have not been fully processed within an acceptable period of time.

Stock in Interim Storage Areas
The warehouse activity monitor displays stock in interim storage areas that has not moved within the time parameters defined in the system. Stock that exists in interim storage areas always indicates incomplete processes. Therefore, any stock that remains in interim storage areas for a lengthy period of time is considered to be critical.

For stock in interim storage areas, the warehouse activity monitor can display the following open processes:

  • Critical stock in the interim shipping area for deliveries. This can mean that there are open goods issues for materials that have not yet been delivered.
  • Stock in the interim storage area for differences. This can indicate discrepancies (from taking inventory or when confirming transfer orders) that have not yet been cleared.
  • Stock in the interim storage area for posting changes. This means that there may be posting change notices that have not been fully processed.
  • Stock in the interim area for goods receipts. This indicates that there may be goods that have not yet been stored in the warehouse.

Negative Stock
The warehouse activity monitor displays all negative stock that has exceeded the critical time period defined in the system.
The existence of negative stock also indicates incomplete processes that can be displayed by the warehouse activity monitor. For example, these can include:

  • posting change notices that are not completely processed
  • goods receipts processed in WM that were not yet posted in IM

Criteria
For critical stock, you define the critical time period for each warehouse number and movement type in Customizing. Additionally, you can define whether all stock or only stock in dynamic storage bins is to be monitored.

Additional Functions
Using the warehouse activity monitor, you can carry out the following additional function for critical stock:

  • For a critical material, you can display all transfer orders that correspond to the critical quant.
  • In many cases, this makes it possible to determine the reason the critical situation occurred. Frequently, no transfer order exists for a critical stock in an interim storage area. In this case, you can be certain that the critical situation was caused by an IM posting.

Critical TRs for Production Supply
Definition
For this object, the warehouse activity monitor displays inconsistencies in stock quantities that are used for material staging to production. These critical processes can appear during the staging of materials for production orders for which fixed production bins have been defined in a control cycle. Inconsistencies can occur between the transfer requirements and the transfer requirement quantities that are updated in a reservation when

  • Transfer requirements are created manually to supply materials to production storage bins
  • Reservations are deleted without making necessary corrections to open transfer requirements in WM

For PP/PP-PI production orders, when components are deleted or changed, the system modifies the transfer requirements automatically. For repetitive manufacturing, this automatic process is not available. As soon as this connection (and therewith, the reservation) is deleted for which transfer requirements have already been created, the transfer requirements are not modified.

Use
The determination of such inconsistencies is important because they can lead to problems when creating transfer orders for the supply of necessary materials to production.

The warehouse activity monitor is able to determine for which materials and storage bins inconsistencies exist, therefore, making it possible for you to take necessary measures to correct potential bottlenecks in production.

Additional Functions
Using the warehouse activity monitor, you can carry out the following additional functions for materials and storage bins for which inconsistencies are found:

  • You can display transfer orders that correspond to the material and storage bin displayed.
  • You can display all reservations and transfer requirements for the material and storage bin concerned.

Criteria
Unlike the other warehouse activity monitor objects, you do not need to enter any critical parameters for this monitoring function since materials and production storage bins are considered to be critical as soon as the system determines an inconsistency. This is independent of how long the inconsistency has existed.

Using the Warehouse Activity Monitor
Prerequisites
Setting up a Variant
On the initial screen, you can enter a variant so that the system will display only those warehouse activity monitor objects that you want to see on your screen. If you do not enter a variant, all objects that have been activated for monitoring in Customizing appear for selection.

  1. To call up the warehouse activity monitor, choose : Logistics Logistics Execution Information System Warehouse Warehouse Activity Monitor from the SAP menu.
  2. Enter a warehouse number (only one is allowed at any one time) and choose Program Execute.
  3. From the list of objects displayed, select the field Display for all objects that you want to see displayed on the screen for this variant.
  4. Once you have selected these objects, choose Goto Variant Save as variant. The system displays the detail screen for defining variants.
  5. On this screen, enter a variant name and description. Other entries on this screen are optional. The following table provides an example as to how you can use a few of these optional entries.
  6. Optional Variant Limitations

    Optional Variant Limitations

  7. To continue, chose Save. In the future, when you enter this variant on the initial screen, each time you call up the warehouse activity monitor, the system only displays the screen associated with this variant. The selection screen will only appear again if you leave the Variant field blank.

User Parameters
Once you have defined a variant, you can modify the user parameters so that each time a user selects the warehouse activity monitor from the WM menu, the variant assigned to that user automatically appears on the initial screen. To do this, select System User profile User parameters from any menu bar. Enter LVA in the Parameter ID (PID) field and the variant you defined in the Parameter value field.

Procedure
Once you have defined a variant, you proceed as follows to use the warehouse activity monitor.

  1. Choose Logistics Logistics Execution Information System Warehouse Warehouse Activity Monitor from the SAP menu.
  2. Enter a warehouse number and a variant, and choose Sie Program Execute. The system displays the quantity of critical processes in the warehouse number and the date and time of the information.

The date-time-group displayed on the monitor depicts the time the data was actually retrieved from the system. You should set up your system to run reports as often as you believe is necessary.

You can update this information by positioning the cursor on one of the objects and choosing Edit Retrieve new data. When you retrieve new data for an object, the system doesn't wait for the background process (report) that was defined for this object to be executed. Instead, the system executes the report to retrieve the desired information and the quantity and date for that object are updated accordingly.

If you refresh the screen by selecting Edit → Refresh, the system does not retrieve new data, but only refreshes the data on the current screen display.

Status Indicators
Traffic light icons are used for each of the warehouse activity monitor objects to indicate their status. The color of the traffic light indicates the status as follows:

Warehouse Activity Monitor Status Indicators

Warehouse Activity Monitor Status Indicators

Detail List Screen
To display a list of objects with more detailed information from the initial hierarchical tree, position the cursor on a category (for example, unconfirmed transfer orders or one of the subordinate categories) and select Edit Display details.You can modify the way this screen displays data by selecting Settings Display variants Current.

From the detail screens, you can carry out functions that are appropriate for each individual object, such as confirming an unconfirmed transfer order. For a description of each of these functions, see the section Additional Functions.

Example: Displaying Unconfirmed Transfer Orders
This topic describes a few functions that you can carry out when you display unconfirmed transfer orders using the Warehouse Activity Monitor.

When you display the hierarchical trees for unconfirmed transfer orders, you can view details for each individual item on the display list. This may assist you in finding out why a transfer order has not yet been confirmed. You can also display all detail information that is associated with the transfer order item.

Analysis Examples
For a particular transfer order, if you choose Edit More functions Information on TO the system displays detailed information that includes both stock quantities and movement data on the same screen. This is useful for data analysis.

If you display a transfer order (TO) with 10 pieces of material that has not been confirmed and the quantity to be placed into stock for a particular storage bin is 10 pieces, you can immediately see that this TO is the only TO with stock to be putaway in the storage bin. If a storage bin is highlighted on this screen, at least one or more transfer orders have not been confirmed for the storage bin.

If 10 pieces of a material are listed for an unconfirmed transfer order but the monitor shows that 100 pieces of the same material are to be stored (status = for stock placement), then it makes no sense to send someone to the storage bin to check to see if the 10 pieces are already there because there are still 90 pieces that are to be putaway in the bin.

Previous activity
If you choose Edit More information Processing information the system displays a window with the last 10 actions regarding the item marked with the last action at the top. The user and time of the action are noted at the top of the window.

Blocking Bins
You can block source bins, destination bins and return bins.
Partial Picking with Return to Bin: If material cannot be placed into a bin for any reason, you can choose Goto _ Block storage bins to prevent any further processing while someone checks the corresponding bins.

Additional Options
If another user is processing stock in a bin or the bin itself, the system highlights that item in red and it cannot be accessed as long as it is being processed. This means that you may not always be able to use such functions as Block all bins or Confirm all bins. If you position the cursor on red highlighted items and select Log, the system displays a message to explain why it is highlighted.
