FPN: Detailed Navigation does not show any entry on consumer portal when Remote Role(RRA) is accessed

You have configured Federated portal network between two portals and When a remote role(through RRA- remote role assignment) is accessed on consumer portal, then DTN does not show any entry for the role,hence no content in content area. The same role shows DTN entries on producer portal.

Troubleshooting steps:

1. Gather diagtool traces for the issue simultaneously on consumer and producer portal with increased severity for the locations:
   com.sap.portal.fpn = All
   com.sap.portal.ivs.globalPortal = All,
   com.sap.portal.SOAPLogger = All,
   com.sap.engine.services.rmi_p4 = All
2. Analyze the traces for Red Errors and you will see the below information:
