Storage Locations in TRs, TOs and Posting Changes - SAP WM

Storage Locations in TRs, TOs and Posting Changes

Use
If you plan to store and manage the stock of several storage locations in the same warehousing complex, you can assign any number of plant/storage location combinations to the same warehouse number. Reasons for doing this include:

  • Representing the ownership status of more than one company
  • Making planning decisions at this level

Prerequisites
When you assign several storage locations to a warehouse to display the ownership status of the companies for the goods stored, and the goods movements between storage locations are initiated solely via IM postings, no further Customizing settings are required. You only need to assign the storage locations to the respective warehouse number.

To uniquely identify stock in WM when taking physical inventory, for example, you sometimes need to enter the storage location in addition to the plant. The system also supports scenarios in which the system manages stock in interim storage areas in different storage locations in a different manner than it manages the stock in the warehouse.

For example, this may occur in an independent storage area in production or when you need to separate stock during when it is received for putaway using special storage locations.

In such scenarios, there are putaway and picking requirements for a storage location for which there is no stock in the warehouse. In this case, you need to determine the storage location to which the stock belongs and then generate posting changes for the respective stock between the different storage locations involved in the IM component.

Such posting changes can either be processed immediately (and automatically) after confirming the transfer orders or they can be processed accumulatively using a batch run of the report RLLQ0100. If an error occurs, you can define a user who will be informed by a mail message. This person can then execute the posting change manually using the transaction LQ01. To activate these functions, additional settings in Customizing to control storage locations and posting changes are required.

Storage Location Reference
To simplify the control per storage location, you can assign an arbitrary 2-digit selectable storage location reference to the plant/storage location combination. This storage location reference is used in the following two instances:

  • To determine the WM movement type
    The storage location reference is a key field used by the system to determine the WM movement type for an IM posting If you have similar goods movements for different storage locations, the system can post these movements to different interim storage areas.
  • To determine the storage types
    The storage location reference is a key field in the storage type search table in Customizing. This makes it possible for you to control different storage types for both putaways and picks based on the storage location.

Possible Scenarios Based on Storage Locations
The following scenarios based on storage location assignment are provided as examples for implementation in your warehousing complex.

Scenario 1:
One Storage Location per Plant in One Warehouse Number
For this scenario, other than the assignment of the plant/storage location to a warehouse number, there are no additional customizing settings necessary. Within the transactions of WM nothing must be entered into the field Storage Location since the storage location is unique and can always be taken from the values assigned to the warehouse number and the plant.

Scenario 2:
Several Storage Locations per Plant in One Warehouse Number
The storage location displays the actual owner of the stock. Stock movements between the storage locations are always initiated via postings in the Inventory Management component. For this scenario, you need to assign the corresponding plant/storage location combinations to the warehouse number. Additional customizing activities are not necessary.

In this scenario, the system can no longer determine the storage location from the contents of the fields Plant and Warehouse number automatically. When the system creates transfer orders for deliveries or transfer requirements, it copies the storage location from the reference document.

When you create transfer orders without a reference document manually, you must enter the storage location in addition to the plant. For inventory taking, this is also necessary for stock that is found in a storage bin that is not in the system.

Scenario 3:
Several Storage Locations per Plant in One Warehouse Number (where the stock is managed differently in interim storage types than in the warehouse itself)

Possible-Scenarios-Based-on-Storage-Locations

Example: Stock Movement from GR Area
This example describes a sample scenario in which more than one storage location for a plant are assigned to one warehouse number.

Scenario:
Stock that is located in interim storage areas for goods receipts is managed in plant 0001 storage location 0090. As soon as the goods are moved physically into the warehouse, a posting change converts the stock so that it is in plant 001 storage location 0091.

The reason for this scenario could be to make the goods available for deliveries when the goods receipt processing has been fully carried out. This is possible using this scenario by allowing deliveries to pick stock only from storage location 0091.

Prerequisites
The following Customizing settings are necessary for this scenario:

  • Storage location 0090 and 0091 of plant 0001 are assigned to warehouse number 001.
  • Storage location 0091 is defined as the standard storage location.
  • The indicator for storage location 0090 is set so that it is not be copied into the transfer requirement.
  • Settings are made for interim storage type 902 such that the stock of this storage type belongs to plant 0001 storage location 0090 and that the posting change is to take place cumulatively.

These settings will result in the following process for a goods receipt for a purchase order:

  1. In the IM component, a goods receipt is posted for purchase order number 45004711 to plant 0001 storage location 0090.
  2. As a result, a quant is posted in WM to the interim storage area for goods receipts 902 in storage bin 45004711. The storage location in the quant is 0090.
  3. At the same time, the system creates a transfer requirement. Since the indicator is set so that the storage location is not to be copied into the transfer requirement, the transfer requirement contains no reference to a storage location. For this reason, when the system creates a transfer order for the transfer requirement, the system assigns the standard storage location 0091 to the transfer order.
  4. As a result, the transfer order creates a negative quant in the interim storage area for goods receipts 902 in storage bin 45004711 with storage location 0091 and a positive quant in the warehouse also with storage location 0091.
  5. After you confirm the transfer order, a posting change (storage location to storage location) must be carried out for the stock in IM.

General information about the posting change:
You set the time for the posting change using the indicator "Combine Posting Changes" under Interfaces/Inventory Management/Define storage location control in Customizing. If you set this indicator, the system carries out the posting change using the Report RLLQ0100. You can plan this as a batch job or start it manually using transaction LQ01. If this indicator is not set, the system carries out the posting change in the background immediately after you confirm the transfer order. For transfer orders that are defined for immediate confirmation, the system carries out the posting change immediately after it creates the transfer order. In both cases, the posting change (transfer posting) takes place in IM with the defined movement type (storage location to storage location). If an error occurs, and you have defined a mail indicator in Customizing, the system sends a message to the user assigned.

In both cases, the system always carries out the posting change for the available quantity of the quant. The system converts quants whose storage location is different from that defined for this storage type in Customizing (T320A). The posting change takes place directly in the storage bin 902 45004711. Both of the quants in this location are deleted and the system does not create a posting change notice for this process. A posting change such as this one can only take place in storage types that are defined for a direct posting out of IM. The system checks this for the storage type in Customizing.

This process is intended for available unrestricted use stock. For transfer requirements with the stock category "Q" (inspection stock), "R" (blocked stock returns) and "S" (blocked stock), the system routinely copies the storage location into the transfer requirement. Because of this, the system also creates the transfer order in this storage location and no posting change (transfer posting) takes place in the IM component. For this stock, we recommend that you carry out these posting changes together with other conversions to available stock.

Example: Material Staging for Production
This example describes a sample scenario in which more than one storage location for a plant are assigned to one warehouse number.

Scenario:
Stock that is physically located in production is managed in plant 0001 storage location 0092.Stock located in the warehouse is managed in storage location 0091. As soon as the goods are moved physically to production, a posting change takes place so that they are managed in plant 001 storage location 0092.

For the following example, it is assumed that the WM-PP interface is active and that the stock supplied by WM will be moved to storage type 100 in production.

Prerequisites
The following Customizing settings are necessary for this scenario:

  • Storage location 0091 and 0092 of plant 0001 are assigned to warehouse number 001.
  • Storage location 0091 is defined as the standard storage location.
  • The indicator for storage location 0092 is set so that it is not be copied into the transfer requirement.
  • Settings are made for production storage type 100 such that the stock of this storage type belongs to plant 0001 storage location 0092 and that the posting change is to take place cumulatively.

These settings will result in the following process for a the staging of materials for a production order.

  1. In the production order component, you enter plant 0001 storage location 0092. The storage location of the production supply area (PSA) is also 0092. Material staging is initiated for production order 10004711.
  2. Based on the material staging, the system creates a transfer requirement in WM.
  3. Since the indicator is set so that the storage location (0092) is not to be copied into the transfer requirement, the transfer requirement contains no reference to a storage location. For this reason, when the system creates a transfer order for the transfer requirement, the system assigns the standard storage location 0091 to the transfer order. This means that the system will only select (pick) quants in the warehouse (0091) to be moved to storage type 100.

  4. As a result, the system creates a positive quant for the transfer order in storage type 100 with storage location 0091.
  5. After you confirm the transfer order, you must carry out a posting change (storage location to storage location) for the stock in IM. For this posting change, the system deletes the quant in storage type 100 (storage location 0091) and creates a new quant with storage location 0092.
  6. The goods issue posting for the production order (which takes place later) results for storage location 0092 thus reducing the stock in the quant.

For this scenario, you need to ensure that when the production order is released, there is no stock of the material available in storage location 0092. In this case, you should only carry out the capacity check at the plant level.

General information about the posting change:
You set the time for the posting change using the indicator "Combine Posting Changes" under Interfaces/Inventory Management/Define storage location control in Customizing. If you set this indicator, the system carries out the posting change using the Report RLLQ0100. You can plan this as a batch job or start it manually using transaction LQ01.

For transfer orders that are defined for immediate confirmation, the system carries out the posting change immediately after it creates the transfer order. In both cases, the posting change (transfer posting) takes place in IM with the defined movement type (storage location to storage location). If an error occurs, and you have defined a mail indicator in Customizing, the system sends a message to the user assigned.

In both cases, the system always carries out the posting change for the available quantity of the quant. The system converts quants whose storage location is different from that defined for this storage type in Customizing. The posting change takes place directly in the storage bin of the quant. Both of the quants in this location are deleted and the system does not create a posting change notice for this process. A posting change such as this one can only take place in storage types that are defined for a direct posting out of IM. The system checks this for the storage type in Customizing.
