"Error Found Retrieving Data" when Expand all or Refresh EVDRE Report

Hi all,

I get the message error "Error Found Retrieving Data" when I push the buttons Expand All or Refresh in an EVDRE Report.

Some info:

- BPC NW 7.5 SP 15

- happens in the Development system but not in the Production system

- SLG1 log error:

The report is a static one (no expansion range active) and the strange thing is that I have this issue if I modify the Row Key Range only in a specific way. I've made some tryouts and here's the situation:

One possibile solution that works is using EVGET for the first scenario but I would like to know the reason of this.

Thanks,

Michele
