Testing Flow Steps Before Running a Flow Service
 
Opening the Data Mapper View
Testing a Flow Step in the Data Mapper View
As you construct a flow service, you can separately test the INVOKE or MAP steps that you plan to use in the flow service. For each step, you can provide relevant inputs, run the step, and check the output before running the entire flow service. This approach helps in early validation of a MAP or INVOKE step before it passes data to the next step in the flow.
You need to use the Data Mapper view in Designer for testing the flow steps.
