After a BW SP upgrade you might get the following error at query execution
EError in BW: error creating tmp table RS_EXCEPTION 105error creating tmp table
AAn error occurred when getting data from the processor. BRAIN 670
I>> Row: xx Inc: IF_RSDRH_HIER_STORAGE~CREATE Prog: CL_RSDRH_DBTAB_STORAGE RS_EXCEPTION 301CL_RSDRH_DBTAB_STORAGE
This seems to be an error that occurs regularly on BW systems after an upgrade. To solve it try deleting the temporary tables with the report SAP_DROP_TMPTABLES (see SAP notes 698280 and 449891)..
You should run report SAP_DROP_TMPTABLE + Option “Temp. Hierarchy Table (02/08).
Once done, execute again the BEx report in RSRT. The error message should not appear anymore.
