Configuring the DataFlow-Execute method for a data flow with abstract output

Version:

You can automate data management operations for a data flow with abstract output by using the DataFlow-Execute method. You can perform these operations programmatically, instead of doing them manually.

  1. Start the DataFlow-Execute method by creating an activity rule from the navigation panel, by clicking Records Technical Activity Create .

    For more information, see Creating an activity.
  2. Click the activity Steps tab.

  3. In the Method field, enter DataFlow-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. In the Data flow field, enter the name of a data flow with abstract output.

  8. In the Operation list, select the type of operation. Depending on the type of operation, specify additional settings by performing the following actions:

    • To define the Browse operation, go to step 9.
    • To define the Browse by keys operation, go to step 10.
  9. Define the Browse operation to read records from the data flow main input by performing the following actions:

    1. 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.

    2. In the Store results in field, define the result page. The result page consists of a page, page list property, top-level page, or top-level Code-Pega-List page.

  10. Define the Browse by keys operation to read records from the data flow main input by using a key by performing the following actions:

    1. Select a key and enter the key value. You can also define the key value through an expression.

    2. Optional:

      To define more than one key, click Add key.

    3. In the Store results in field, define the result page. The result page consists of a page, page list property, top-level page, or top-level Code-Pega-List page.

    For data flows with abstract output and non-stream input, operations that are specific to the Configuring the DataFlow-Execute method for data flows with non-stream input are also available.

  • Data Flows landing page

    This landing page provides facilities for managing data flows in your application. Data flows allow you to sequence and combine data based on various sources, and write the results to a destination. Data flow runs that are initiated through this landing page run in the access group context. They always use the checked-in instance of the Data Flow rule and the referenced rules.

  • Types of data flows

    Data flows are scalable data pipelines that you can build to sequence and combine data based on various data sources. Each data flow consists of components that transform data and enrich data processing with business rules.

  • Methods and instructions by function
  • Building expressions with the Expression Builder

    Author expressions using the Expression Builder by completing the following steps:

  • DataFlow-Execute method

    Apply the DataFlow-Execute method to perform data management operations on records from the data flow main input. By using the DataFlow-Execute method, you can automate these operations and perform them programmatically instead of doing them manually. For example, you can configure an activity to start a data flow at a specified time.
