We are about to go live with our EPDM implementation and I think I may need to change something. Currently we have a Part number variable which is populated using a serial number. The file name is matched to the part number.

I would like to change this around and rather use a serial number to control the file name and then populate the part number field with the file name (excluding the extension.) I can not figure out how to get the part number field to look at the file name for its value.

Should I leave it as it is or would the idea of driving from file name be better practice?

What worries me is that I noticed that I can edit the part number field in the data card after the file as been created which means I can end up with duplicate part numbers if a user manually edits the value in the part number field. I can not get duplicate file names as the "Do not allow duplicate file names" setting has been turned on.

Thanks
