Payment Request Center Security Issue

Hello,

We are trying to implement Payment Requests for Accounts Payable. We have created a role and perm list that grants access to Menu PAYMENT_REQUEST, Component PR_REQUEST and Page PR_CENTER, and gave several users that role. However, they do not have the Payment Request Center as an option in their Employee Self-Service navigation. We have run Portal Sync.

What else could be causing the issue. Is this something unique to Employee Self-Service? Is there something else that needs to be done to get these users access?

Thanks in advance.
