Hi,
We had the same issue.
After some research we found these fields were added in OITW(2007 - 9.0 version):
PurBalAct
WhICenAct
WhOCenAct
WipOffset
StockOffst
DftBinAbs
DftBinEnfd
Freezed
FreezeDoc
If you just remove those (and most likely those with Bin) in it, it should work again
Kind regards
Frederik
