HI
.1. In OBYC, check the Account Determination check box is not ticked. This means the account determination is not done from OBYC. It is done as per the account assignment entered in PO. 2. Check  OMJJ go to OMJJ and enter teh movement type 101and go to Account geouping folder and click on it
all the line which has KBS in TEKey check the Check acc *** check box than you will not get this error.
3.Goto OBYC double click KBS and enter your valuation grouping code and assign to the G/L accounts and save
