ABAP OO application exception and passing parameters back tow orkflow container

[Alon Raskin]

Dave,

I haven't done any ABAP OO in Workflow yet (I was really turned off by the fact that I couldn't do polymorphism using interface inheritance) but perhaps alternate binding would do the trick for you?

Hi Florin,

I am using a workflow task based on an OO method in a class, so am not using swc_set_element (no BOR). But I guess I could return a result value and check that in the workflow. Seems a bit limited though. If I run the method in SE24 and the exception is raised the exporting parameters are returned, but not in the workflow. One thing i could try is fill the binding from the method to task container and see if it makes any difference. If not I'll go the result way I guess.

Dave

Hi Dave,

the data flow is aborted on an exception. Only the message variables (sy-msgv1,..v4) and the exception number is passed back.


---> follow-up:

If you want to have a workflow activity with more outcoming threads (like you have it in the generic user decision steps), you could use the following:
- Double click on the object's method
- Choose tab "Result type"
- Give a reference to a field here, that again refers to a domain with fixed values, e.g.
  SE Step executed
  X1 Exception 1
  ....
  (I think there's a restriction to 4 characters as the key)
- In the object's method implementation use the macros to set the result
  swc_set_element container RESULT 'SE'.
  swc_set_element container RESULT 'X1'.

This way you'll have a dataflow.

Best wishes,
Florin
