Thank you Juergen, I will contact SAP to find the reason and let you know the solution once i get it.
Please find the answers for your questions.
How do you know that the indicator was originally set?
- This is originally indicated by user and informed me and its usual practice many of the purchase source material will mark MRP1 in the source list.
Is this a single case or happened it to many other materials too?
- This issue happened many other materials too
Did this start issue start after a certain event, e.g. after an upgrade?
- This is happening past 2-3 months, there is no recent upgrade or system changes done during this time.
Do you know if you make use of BAdIs for source lists? in that case you may check OSS note 2288986 - During the source list creation/updation the BADI values are not updated correctly
- BADI hasn’t implemented for this sourcelist
Regards,
Raj
