Hello Peter,
With regards to your questions..
1 - Yes I have released (release approved ) the SA, and the scheduling lines are generated from MRP, meaning I didn't perform manual entry maintainance in ME38. Further, I have executed the ME84 with green color line as output. May I know what is your purpose of this question?
2 - I went to ME38 and manually inserted one line into the SA. See below figures
and in MD04...
Finally, again, with a failed MIGO-GR on this schedule line with posting date as 18th Nov.
Looks like I need to execute the source changes as specified on the note 741385 provided by Jurgen then.
I will find out from business first if this is allow.
Thanks,
Daniel
