Configuring the DataSet-Execute method for Stream

You can automate data management operations on records that are defined by the Stream data set by using the DataSet-Execute method. You can perform these operations programmatically, instead of doing them manually.

1. Create an activity rule from the Explorer panel, by clicking Records > Technical > Activity > +Create, to start the DataSet-Execute method.

   For more information, see Activities - Completing the New or Save As form.

2. Click the activity Steps tab.

3. In the Method field, enter DataSet-Execute.

4. In the Step page field, specify the step page on which the method operates, or leave this field blank to use the primary page of this activity.

5. Optional: Enter a description for the method.

6. Click the Arrow icon to the left of the Method field to expand the Method Parameters section.

7. Specify the following parameters:

   1. In the Data Set field, enter the name of the data set that is used to represent a stream data source.

   2. In the Operation list, select the type of operation. Depending on the type of operation, specify additional settings.

      • Save — Save records passed by a page or data transform in the stream data source.

        • Select the Save list of pages defined in a named page check box to save the list of pages from an existing Code-Pega-List page.

      • Browse — Read all records from the stream data source.

        • In the Stop browsing after field, enter a value to define the time threshold for stopping the browse operation (in seconds, minutes, or hours).

        • In the Maximum number of records to read field, enter a value to define the threshold for stopping the browse operation. You can also define this value through an expression.

        • In the Store results in field, define the result page. The result page consists of an existing Code-Pega-List page.

      • Truncate — Remove all records from the stream data source.
