We are developing the user exit COOMKS02, EXIT_SAPLKMA1_003, ZXKM1U03.
We have written some check while saving the cost center. The error message is displayed correctly.
But after the checks are satisfied the object is locked and we are not able to save the cost center.
The error displayed is<b> object number was already assign</b>
Can u suggest how we should go about to eliminate this error ??
