Data Validation on a UDF Field

131 Views

I am managing an item by SAP Generated serial Numbers, however this item comes with another set of alpha numeric number which I have created a UDF to hold it. I want to ensure that for every serial number there is a corresponding item number.

I want the system to stop any posting that has a serial number but no item number. Please how can I achieve this ?

Many thanks in advance for your support.

Regards
