PO pdf file not opening in SUS Portal after clicking on Print

Hi Experts,

Scenario: After click on the Print option in SUS Portal for a PO it is fetching the pdf file from Application Server and it is giving error while opening like

                  "The file is damaged and could not be repaired ". We are able to see the PO pdf file in Application Server and it is opening correctly but

                   after clicking on the print option in SUS Portal it is failing to open and it is working fine from MM side but it is failing through portal.

Thanks in Advance.

Thanks,

Regards,
