In my company MRP is running as per sales scheduling agreement .
There are few old scheduling agreements which are completed and /Or closed (by selecting Reason for rejection > Poor Quality ) BUT in MD04 we are seeing there delivery schedules .
Please let me know that how to rectify this problem .
In your case the particular sale order MRP has taken place in T.code MD50, once MRP being run for that order that will come in to
T.code MD04,this position you marked the sale order with reason for rejection it will not removed from the list of MD04.
Go to T.code MD02 give material and plant then select the Planning mode 3(Delete and recreate planning data) now it will be
removed from list.
If you don't have authorization for T.code MD02 take PP consultant help or get the authorization form BASIS.
