UOM FIELD CHANGE AS HEAD QUARTERS CHANGES HAPPEN WITH MASS T-CODE

Hi experts,

I have one requirement ,my clients want UOM field in customer master controls changed to Head quarters by using additional customer master fields.We create one Z-table and maintain values in that table .Now client has to change the Head quarters value by using MASS transaction code system giving error message like The value ZWG does not exit in foreign key table TVV1 . We maintain values in head quarters and by using F4 system showing values .

There is any option to use mass transaction code for customized ones .
