Dear Experts,
I would like to have your help on below issue:
The business requirement is to generate a PI document by exception code during picking. Suppose the picker can only find a partial quantity. He enters the actual quantity and the exception code, and after confirm this, a physical inventory document will be generated automatically.
my customizing is as below:
1. define a custom exception code

2. maintain follow-on action

3. Active workflow as below:

but i did not do the customizing for assign internal exception code to exception code, also did not active the pick denial.
and the test configuration of exception code is as below:

Also I use SWDD to set WS78600032 with background processing.
Based on above setting, i did a test with entering the exception code during confirm picking WO . but the result is no physical inventory document generated.
i checked the workflow, it looks every thing is green without any errors.

can anybody instruct me whether I missed some customizing or made a wrong customizing.
Thanks a lot in advance!
