Data Flow transformation shapes cannot be used in combination with the Compose or Merge shapes
Valid from Pega Version 7.1.8
When you reference another data flow from a data flow that contains the Compose or shape, the referenced data flow cannot contain transformation shapes (, , ).
Data flow validation does not currently prevent you from designing a data flow that goes against this design pattern. Make sure that your data flows follow this design pattern by checking the referenced and referencing data flows.
Data flow destination is resolved at assembly time
Valid from Pega Version 7.1.8
Data flow execution always uses the design-time destination data sets or destination data flows, regardless of the input records at run time.
Example:
You create a data flow and set the destination to a specific data set. In the data flow, you use a strategy that produces some results. Regardless of these results, the execution of your data flow always uses the destination data set that you specified when you designed the data flow.
The same applies when you set the destination to a data flow.
