Fee calculation after been posted, if recalculate generates 2 new docs
hi to all, my last implementation of student accounting was with the 4.72 SAP version, now I´m working with version 6.
In the previous implementation (4.72) when we did a fee calculation for a student the system created a fee document. If you tried to recalculate the fee for the same student, with out changing any master data or SC, the system did not create any new documents and we got a message which said: "Doc. was already posted for student 0000101227; no changes allowed for student 0000101227"
Now with this version if I have a student that I have already make him a fee calculation the system creates 2 new documents even though there has not been any changes. One of the documents is a "reverse" of the very first document which was created in the first fee calculation.
The question is how can I avoid this? I think the correct way is to prevent postings if a document has been already posted...
