Hi Janos,
Thank You for your quick response.
I am able to see the link attachment in the Objects and Attachments section but when i click it on the link the invoice image it should get open in SAP Document Viewer it's not opening just doing nothing .
"ArchiveLink Image in workflow screen doesn't work , the image does not open. No error message at all ,just doing nothing when clicking on that link"
But when logged into SAP Portal the same link is opening and able to see the image in SAP document viewer. But from SAP GUI it's not working.
