Hi Jun
My thought was to use this workflow created in S/4 as one of the steps of my BPM process . Not sure if that is what the above link intention was . When I import it , it is showing as a human activity to which I could pass the control and get it back at the end of the completion of the process.
I was trying to create a scenario with the following steps to see if it is feasible .
Steps 1 : Request for creating a new customer is sent from source to SAP PO.
Step 2 : This request is captured in a BPM which calls Create Customer Bapi in S/4 .
Step 3 : The response from the Bapi Create is sent back to BPM From S/4 .
Step 4 : If the customer is successfully created based on the BAPI confirmation , Bpm initiates the workflow for credit limit in S/4 .
Step 5: The workflow in S/4 sends notification to Approver to look at the Credit limit .
Step 6 : The Approver increases or decreases the credit limit . This information is updated by the workflow for the customer in S/4 and the same information also needs to be sent to BPM from the workflow.
Step 7 : Based on information from workflow BPM initiates the information to be sent back to the Source .
Thanks
