Error :
I have configured the PR workflow by department wise and setup approver also. I created new PR and submit it.After submitting it goes to approver based on department.When approver tries to pull up the requisition, that time i got below issue.
You don't have access to this requisition number
Solution :
Go to Microsoft Dynamics GP > Tools > Setup > Purchasing > Purchase Order Processing
Click on the requisition button, and then click on the "check box" for all requisition.
Hope this Helps!
