I have a user Defined Field (customer number) at WBS level and i want to save the project after removing the data ( serial number of customer) from that field but system gives me an error at the time of saving the project that "customer number is required" .
I have checked in OPUK , but all settings are done for INPUT and not for REQUIRED.
Can , anyone tel me that what can be the possible reason for this or what do i have to check ??
