Hi Christoph,
I am very new to AIF. I am trying to define fields check on the incoming IDOC. If field = INITIAL; it will populate the error. It is working as required. But when I am changing the value of the field in /N/AIF/ERR ; and restarting the IDOC ; its again showing the same error. However I can see the value in the segment. What might be the issue. I hope you understand what I am trying to say.
In the last screenshot you can see the edited value in the USNAM field; but again after reprocessing the message from this screen; its showing the same error as in the screenshot 2.
Regards,
Pankaj Sharma
