Hi,
Resolution of two issues mentioned by you are:-
1. So far as the bookings which are needed to be made correct, you need to make CO bookings correct - resultant of reversal of FI document
Hence, Please use kb11n and trf costs across cost objects as posted with FI Document (It will not create Finance document)
2. Regarding dump, please share st22 screenshot and also search in SAP OSS notes, you might find something useful
Thank You
Nishu
