I face a problem in the transaction ME91F. With this transaction we would remind our vendors, that in one case they have to send us some goods in next time and in other case they are overdue with the delivery time.
There are the two message types, ERIN(before delivery date) and MAHN(afte deliver date). Here an example to explain my problem:
delivery date: 24.01.2014
Purchase Value Key: 1st reminder -21 , 2nd reminder 1, 3rd reminder 10
I think the messages depend on this reminder days from the Purchase Value Key, i hope i am right with my assuming.
So in this case the system should only create the ERIN, because of the first reminder(reference date=23.01.2014, see jpg attached).
Not our system, it create the ERIN and the MAHN. I hope anybody can help me with my problem.
