Prohibiting modification, but allowing initial entry
I am using Filemaker Pro 10.0v3 on Windows XP SP2.
I am creating an database to maintain an inventory of each computer my company owns. We place our own barcodes on the computers. I would like to allow our computer analysts to be able to input the barcode number when they are creating the record, but once the record has been submitted, prohibit the barcode field from being changed. So far, I can only do one or the other (either allow entry or prohibit editing, which also prohibits the entry of the barcode for new items). Is there a way to do this? The users are submitting and editing items through IWP. Thanks in advance.
