Portal Independent Navigation Frame (NWBC): POWL authorization

Hi,

Whenever a user logs on to the Portal Independent Navigation Frame in our system with the standard SAP SRM PFCG roles he can't see/query the POWL document list. The document list doesn't return anything. If the same user has authorization SAP_ALL he can see/query his own documents via the POWL.

SU53 tells me that everything is ok whilst i'm certain that certain authorizations are causing 'empty POWL lists'.

What I've already tried:

- Check SU53, nothing.

- Added roles: SAP_BC_UWL_END_USER, SAP_DAL_ADMIN_WORKFLOW_POW, SAP_S_RFCACL, /SAPSRM/ENTERPRISE_SERVICES, /SAPSRM/ADMINISTRATOR_USR

Inputs very much appreciated.

Kind regards,

Tim
