Dear KHF,
Just check at your schedule line category --what was the account assignment category assigned??
Due to this only system catches KOFK in third party/IPO (TAB/TAS item categories)(CB/CS sch.lines)
in normal TAN--will catch KOFI--due to blank at Schedule line CP.
this is what is the differentiating reason with requirement 002/003 in revenue account determination procedures.
Hope this helps.
