I'm not experienced in Web Dynpro for ABAP, but a question came in mind when I first heard about NW BPM 7.3 supporting tasks UI built on WDA: does this mean I can (re)use a standard tx GUI (like Purchase Order creation) from ECC as a task UI? Can I map both input as well as output of this task UI?
Use case is: I need to implement a process where one human task is to create a PO. How I can accomplish that without implementing my own UI (since it is already available in ECC)?
A workaround I sketched (in case I cannot reuse an ECC standard tx GUI) is:
1) Model the human task in the business process and bind it to a Web Dynpro for Java UI
2) Embbed a transaction iView in the Web Dynpro for Java UI (I saw somewhere in this forum that this is possible and that I can map the input of the iView -- not the output)
3) Use an intermediate message event right after the human task, therefore orchestrating the ECC "process" with the BPM process
Would that work? Did someone implement similar use cases?
