We've set up a workflow for purchase orders - the emails are going to the correct approvers
However, the end user clicks on the link to approve and it gives an error message that 'a connection Microsoft dynamics Gp could not be established. be sure that you are logged on to the appropriate company and try again.'
Thought that the approvers didn't have to be GP users - how do they view the PO to approve?
