Hi there!
I have created a batch of XMP files for upcoming games I will be editing. Each XMP has a unique MEID number associated to each game in the Job ID/Trans Ref field. When I load my XMP everything in the IPTC changes except the Job ID field. If there is data already in the field and I load my XMP, the data will stay there while all other fields have been changed with the correct data.
I have attached an XMP file as a reference.
Thank you for your help!
