Hi!
We still don't have a SAP official response but we think that the error is because of the note:
2014811 - Risk Analysis Dump in case of huge data
That we've implemented some days ago as part of the advance corrections of SP07.
The error seems to be related to the following class:
But there are many changes related to such note...So we're not sure about the exact details.
We DE-implemented the note mentioned above and after that the analysis at permission level worked as expected.
Hope to have a SAP response soon, but meanwhile I do not recommend to implement such note.
Thanks!
Diego.
