In an activity, the Obj-List-View can execute a list view rule.
To divide the ListView in to different pages and set the number of records to be displayed in a page.
Exposing a property means to make a property as a separate independent column so that it can be used in sql queries and as a criteria in reporting.
Process Commander stores the values of all aggregate properties and some Single Value properties in a BLOB column (the Storage Stream) usually in a compressed form. Such properties cannot support selection in list view and summary view reports, and can slow retrieval and processing in other operations
1. Select Tools > Database > Modify Database Schema.
2. A list of databases identified in Database data instances appears. Select a database and click Next .
3. A list of tables in the selected database appears from Database Table instances. Select a table.
4. Click Explore Columns .
5. The resulting List of Classes window displays the number of rows in the table, the number of columns in the table and a list of the classes assigned to that table. The Properties Set to Be Visible value counts the properties for which the Column Inclusion value is Required or Recommended. This Column Inclusion value is advisory, and does not indicate whether the property is exposed — corresponds to a column. The Count column shows the total count of properties in this class plus those its parent classes.
6. To see the columns currently defined in this table, click the numeric link labeled Number of columns in this table.
7. The List of Database Columns window shows the column name, column data type, and column width in bytes for each column in the table.
Declare Index rule is a better approach.
1. Create a concrete class derived from the Index- base class.
2. Create Single Value properties in the new class to hold values of the embedded values.
3. Create a Declare Index rule with the appropriate embedded Page Context value that copies the embedded values into a new Index- instance.
4. Save the Declare Index rule. It executes immediately, adding and deleting instances of the new class.
5. Expose database columns corresponding to the Index- class.
6. Reference the Index- properties in the list view rule.
We can refer the properties in Display tab without exposing. But we cannot refer the property without exposing in Criteria fields of the Content tab.
Step1: Create Activity in Our Class and create the New page
Step2: write a query and store in variable.
Step3: call the listview as Call Rule-Obj-ListView
Step4: Write the another activity in Embed-ListParams
Step5: create the parameter. This parameter get the sql query from previous activity
Step6: write Java method The java code in this method is Get the page from pyContentPage if page already exists. If page is not available it creates the new ContentPage.
In this code get the sql query from the above parameter and pass this query and above created ContentPage as parameters to this tools.getDatabase().executeRDB(query, pagename) method.
Using Join tab in Reports
Write a database View. In this view logically combine the Two different tables.
Create class for this logically combined Table.
Write the List View. Applies to class is class of the Combined table. So we can refer the properties of both the tables in list view.
HTML Property rules appear in list view and summary view rules to define the appearance of values in reports.
Question 14. Consider This Scenario: I Need To Generate A List View Report Of All The Work Objects Created On A Particular Date And Then I Need To Include This List View In A Section. How This Can Be Done?
Select .pxCreateDateTime ( an exposed property ) under criteria and give the value you are looking for.
To include it in a section, check the embedded check box and customize the HTML of the section. In that we need to access the list view in a JSP tag or In section Property is DisplayAs ListView.
List view is generally used for complex queries where sorting is required and also we can retrieve less information using Paging.
List view (an instance of Rule-Obj-ListView ) is used to define a custom report or personal version of a report.
A list view can be configured as follows:
List view can be accessed from an activity or html as follows:
Summary views are used to create reports which are grouped by certain criteria and can be later drilled down.
A Summary view can be configured as follows:
a. Obj-Validate–we can referred this method in Activities and in flow actions at Validate Rule field.
b. Edit-Validate—- we can refer this in property form at edit-validate field and in activities through property-validate method.
Note: I think Obj-Validate is used for Server Side Validation and Edit-Validate is used for Client Side Validation.
For this we have to use theProperty.addMessage(“your message”) tag.
If the property has a html property, the tag <pega:include name =”Messages”/> tag must be include.
Use the Activity-End method to cause the system to End the current activity and all calling activities.
Ex:if Alpha calls Beta, which calls Gamma, which calls Delta, which performs the Activity-End method, all four activities are ended.
The Exit-Activity method ends the current activity and returns control to the calling activity.
Page-Copy method is used to copy the contents of a source clipboard page to a new or previously created destination clipboard page. The source page is not altered.
After this method completes, the destination page contains properties copied from the source page, and can contain additional properties from a model.
The Page-New method is used to create a page on the clipboard. The new page may be a top-level page or an embedded page.
We can identify a model to initialize the newly created page. The model can set values for one or more properties.
Page-Remove method is used to delete one or more pages from the clipboard. The contents of the database are not affected.
Use the Page-Set-Messages method to add a message to a clipboard page. Like a message associated with a property, a message associated with a page normally prevents the page from being saved into the database.
Property-Set-Message method is used to associate a text message with a property or a step page. The system reads the appropriate property and adds the message to the page. We can provide the entire literal text of the message, or reference a message rule key that in turn contains message text. (Rule-Message rule type).
Use the Property-Map-DecisionTable method to evaluate a decision table rule and save the result as the value of a property.
The Property-Map-DecisionTree method is used to evaluate a decision tree rule (Rule-Declare-DecisionTree rule type) and store the result as the value of a property.
The Property-Map-Value method evaluates a one-dimensional map value (Rule-Obj-MapValue rule type) defined in the parameter. The method sets the result as a value for a Single Value property.
The related method Property-Map-ValuePair works similarly for two-dimensional map values.
Property-Remove method is used to delete a property or properties and its associated value from the step page or another specified page. This does not affect the property rule, its definition.
Property-Set method is used to set the value of one or more specified properties.
The Show-HTML method is used to cause the activity to process an HTML rule and send the resulting HTML to a user for display by Internet Explorer. This may involve the interpretation of JSP tags (or the older directives), which can access the clipboard to obtain property values, or can insert other HTML rules, and so on.
The Show-Page method is used to send an XML representation of the step page to a user’s Internet Explorer browser session, as an aid to debugging.
Note: Use Show-Page and Show-Property only for debugging.
Obj-Browse method is used to search instances of one class and copy the entire instances, or specified properties, to the clipboard as an array of embedded pages.
Only properties exposed as columns can be used as selection criteria. However, values of properties that are not exposed as columns, including embedded properties, can be returned.
Obj-List-View method is used to execute the retrieval and sorting operations, but not the formatting and display processing, of a list view rule.
The system uses rule resolution to find the list view rule and executes it, but does not produce any HTML output display.
Obj-Open method is used to open an instance stored in the PegaRULES database or in an external database linked to an external class, and save it as a clipboard page.
The system uses the specified class and key fields to find and open the object and place its data into the specified step page. The system searches up the class hierarchy as appropriate to find the instance. If it finds the specified step page, the system clears any data that is on it and reuses the page. If no existing page has a name matching the specified step page, the system creates a new page.
Use the Obj-Open-By-Handle method only if we can determine the unique handle that permanently identifies which instance to open. Otherwise, use the Obj-Open method.
Obj-Delete method is used to delete a database instance corresponding to a clipboard page and optionally to delete the clipboard page too. We can cause the deletion to occur immediately, or until execution of a Commit method.
This method can operate on objects of both internal classes (corresponding to rows in a table in the PegaRULES database) and external classes (corresponding to rows in an external relational database).
The Obj-Delete method uses the class of the page to obtain the appropriate Rule-Obj-Class instance. It uses the table name, key fields, and other aspects of the class rule to mark the instance for deletion.
We can reverse or cancel a previously executed Obj-Delete method by using the Obj-Save-Cancel method.
Commit method is used to commit all uncommitted database changes. This method writes all the instances specified by one or more earlier Obj-Save methods to the PegaRULES database (for internal classes) and to external databases (for external classes).
Obj-Validate method is used to apply a validate rule (Rule-Obj-Validate rule type) for the object identified on the primary page or step page.
A validate rule (Rule-Obj-Validate rule type) can call edit validate rules (Rule-Edit-Validate rule type).
RDB-Save method is used to save the contents of a clipboard page into a row of a relational database. The system saves the properties on the specified step page to the specified table in the database.
This method operates in conjunction with a Connect SQL rule that contains SQL statements such as INSERT, UPDATE, and CREATE statements on the Save tab.
No. Agent schedules cannot be created manually.
The Agent Manager on our Process Commander system generate at least one agent schedule instance for each agents rule.
By default, the Agent Manager checks for new or updated agents rule once every ten minutes.
After we create an agents rule, the Agent Manager generates one Agent Schedule instance for each node running on your Process Commander system the next time it checks for new agents rules.
Escalation refers to any processing within a Process Commander application that causes high-priority work objects to become visible to users and managers and to be processed sooner rather than later.
The numeric property known as urgency determines the order that assignments for that work object appear on worklists. Escalation recalculates the urgency value to reflect its age, impending due date, or explicit management inputs.
Escalation can occur through a service level rule associated with the flow and through background processing by the Pega-ProCom agent.
At runtime, the system runs this activity before it does other processing for this flow action. This activity is not visible on the Visio flow diagram. This activity executes only once, the first time a user selects this flow action for this assignment.
Activity to run after other successful processing of this flow action.
For screen flow rules By default, when this flow action appears as a step in a screen flow rule, and the user at runtime clicks away to a different step in the screen flow rule, this activity rule does not run. To cause this activity to execute when the user clicks away to a different step, select the Post Action on Click Away? check box on the Assignment shape properties panel.
A local flow action permits users at runtime to update, but not complete, an assignment. Like connector flow actions, local flow actions are referenced inside an assignment task in a flow.
At runtime, users can select local flow actions to update assignment or work object properties, change the assignee, and so on but do not complete the assignment. If a service level rule is associated with the assignment, the service level continues to run.
Local flow actions always are optional. Users may perform none, one, or multiple local flow actions, or repeat a local flow action multiple times.
On the Action tab of the Flow Action form, we can mark a flow action rule as local, or connector, or both.
