POR (Purchase Order Response): Approve/Reject buttons not functioning

Hi folks,

In SRM 5.0 extended classic scenario, a POR is sent to EBP from SUS. The POR is outside tolerances so it triggers workflow -WS14500019. When a user goes into their Approval Inbox they have the option to Approve or Reject the POR using the Approve/Reject icons.

When a user clicks on either the Approve or Reject icon, a message appears at the bottom of the screen:

"Work Item is been Processed, Please Wait"

When this message disappears the work item is not processed and remains in the Approver's inbox unprocessed.

If anybody has any suggestions it would be greatly appreciated.

Regards,

Pat
