Access denied error during Product Receipt update

Hi, I had provided the security role to a warehouse employee to post the product receipts through the 'Procurement and Sourcing>>Periodic>>Purchase Orders>>Product Receipt". I get the below error, would be very helpful if someone could provide a solution soon. Thanks in advance.
