hELLO ,
Please kindly review following comment that we usually referred
to our customer pertaining the budget issue in MR8M:
When you try to reverse IR via transaction MR8M, the system
decreases the actual values of the account assigned object (order,
WBS element) in year 2011 but also tries to re-create the commitment
values of this object according to the corresponding PO.
If this PO, however, was created in - let's say - 2010, the system
tries to increase the commitment for year 2010 again, resulting in the
error you experienced since the 2010 budget could be
already (over-)spent.
If this is your situation, the solution to overcome the problem is
to run commitment carry forward for your object to unassign the
commitment from 2010 and to assign it to 2011 instead. If the
framework is like above described, after this, the reversal of IR
document via txn MR8M should be possible.
Hope this helps,
regards
Ray
