How to make Document category field as “Mandatory” in Invoice Header

Content

I made Document category field as “Mandatory” through Sandbox, its working for Manual Invoices correctly.

If I Interface any Invoice through interface and load invoices through FBDI template, this is not validating and NOT error out.

Customer requirement to make this field mandatory. Until unless user enter this field in FBDI or through interface file. That invoices should not get processed.

Now it’s not working for these two types interface invoices, FBDI upload.

There might be chances user might enter incorrect Document category in FBDI, for those system is validating/ not validating.
