Running a data flow in single mode

Use the Call instruction with the Data-Decision-DDF-RunOptions.pxRunSingleCaseDDF activity to trigger the execution of a data flow in single case mode. Only data flows with an abstract source can be executed in this mode.

1. Create an instance of the Activity rule by selecting Activity from the Technical category.

2. In the activity steps, use the Call Data-Decision-DDF-RunOptions.pxRunSingleCaseDDF method.

3. Click the arrow to the left of the Method field to expand the method and specify its parameters:

   • Name of the data flow that you want to run

   • Page to be used as input

   • Page to store results

4. Optional: Click Jump and define jump condition to handle data flow run failures in this method.
   1. Enable the condition to be triggered after the action.
   2. Configure which step to jump to when an exception occurs.

5. Click Save.

Although the data flow itself does not contain the Parameters tab, you can pass a number of parameters to the data flow execution:

• Param.RunId - Current data flow run ID, for example, DF-1. This parameter is empty in single case execution.
• Param.PartitionKey - Partition key value. This parameter is set during distributed data flow runs.
