Hi Tu,
Maybe there is an inconsistency with the navigation attribute table of infoobject 0COSTELMNT.
Can you please check this as follows:
- Transaction RSRV
- All Elementary Tests
- run tests:
- Compare sizes of P or Q and X or Y tables for characteristic &1
- SID Values in X and Y Tables
=> If errors are found try to repair them using the "Correct Error" button.
BR Bernhard
