Cloud 24R1 - The need is Supplier Request document attachments to be brought over to the Supplier record when created from the Supplier Request.

I tried creating an OCT as per the screen shot. The Supplier_ID key does exist in the SupplierRequest, but I think it's not working as it's a populated field instead of a Key field.

 When I run the test, it states it has “passed” however the Source Key populates with REQUEST_ID, not SUPPLIER_ID.

Any solution here? Or not a feasible solution?
