Unfortunately, that didn't work. I've shortened the file path in order to test the load file, but it's still giving me an error.

When I click on the link in my load file, it takes me to the PDF, but still get "Invalid data 'file://S:Accounting/25999_169_Folio.pdf' for field called 'Hdr-Attach PDF' of record 1. when I try to import to A/P.
