Hi everyone, I'm trying to create a workflow that sets Package Tracking Number field in Packages subtab in Item Fulfillment to mandatory when editing the record. Problem is that I have no visibility on that field. In the workflow I can only see Items subtab. Any ideas?

This cannot be done via workflow

Thanks Kevin. Is there a way to source it from another custom field that I set as mandatory?

This would require scripting to accomplish

I don't seem to have visibility on it at all
