We had recently implemented MM-FI module. Invoice is parked/post through transaction code MIR7/MIR6. We have applied the user exit for maker checker validation while parking and posting the document. So the person who will park the document will not able to post the same. The user exist was working fine in production up till now.
Yesterday,on PROD system maker was able to park & post the document. while doing the same he has followed the below process :
Parked the invoice through t code - MIR7
Changed parked document through - FBV4 (Only posting date changed)
While changing parked document, he was able to post the same.
We are also able to produce the same case only once in the quality system
Kindly suggest if any standard validation is availabe for the same.
Thanks & regards
