You don't have access to this requisition number in Dynamics GP

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!
