Thanks for reading my writing.

Hello,

The exception described is in the FPN RDL scenario - the hidden area that holds all the data for RDL has a different content than expected.

As you didn't mention the SP level you are using, Please have a look at SAP note:

1634171 - FPN Inconsistency and broken RDL Tool

If using this tool does not solve your issue, then please record the location of: com.sap.portal.fpn.runtime using the Troubleshooting Wizard. Then attach the trace generated.

To get more information on how to use it, you can read the following KBA, which includes some screenshots for better understanding (you just need to add the location mentioned by me):

1921472 - How to use the Troubleshooting Wizard for collecting traces using custom locations

Thanks & regards,

Michal Zilcha-Lang
