Role to configure TAB for Procurement

Summary

Role to configure TAB for Procurement

Content

I have Procurement Administrator Role, but still, Manage Mapping Sets, Manage Account Rules, Manage Transaction Account Definitions and Manage Subldeger Accounting Option are greyed out for me in the Define Transaction Accounting for Procurement

I am not sure but it should not be greyed out for the user having Procurement Administrator Role.

Do I need any other role?

As per organization policy, I can't get the Application Implementation Consultant and Financial Application Administrator role.
Is there any other role that will allow me to configure TAB for procurement?
