Hi,
the screenshots show a snippet of error message.
You might want to take this further, and trace the DSL_Bridge APS + WebIntelligence Processing Server. Then look: what Errors |E| do the trace logs show? In parallel, trace in BW using transaction RSTT or ST05. What's happening in BW at that instant?
Stepping back for a moment, this looks like a pure BW error - the 'bain' code is definitely an ABAP termination. See the information:
" warning : ( brain 746 ) initial range-low for customer exit " <--- that error text is searcheable on the wider internet, and will be an ABAP problem with the routine. Similar to this thread http://scn.sap.com/thread/1690600
Regards,
