Diagnosis
The contract end date determined by the system is before the contractstart date.

System Response
When you enter the contract end date at header level, the systemrecognizes that the current item has not yet started.
Since this would lead to inconsistencies at item level, the date couldnot be copied.

Procedure
Check the item contract data on the screen
Item/Contract/Contract data
and maintain it manually if necessary.
If required, you can enter a reason for rejection or delete the itemmanually.
