Reading statistical data in BI NW2004s (using RSRT)

Hello,

I executed a query via RSRT and flagged the option "Display statistics".

The statistical data after execution of the query is displayed on 2 tab pages (Frontend/Calculation Layer & Aggregation Layer).

How can I derive the overall runtime for the query from that data? I already read the SAP documentation (http://help.sap.com/saphelp_nw04s/helpdata/en/43/e39fd25ff502d2e10000000a1553f7/frameset.htm) but it doesn't really answer how to derive the overall runtime.

I do not/can not use the other methods (like ST03 for instance) to derive query runtime information.

Thanks for any answers in advance.

Regards,

Philipp
