Setting an OLAP Trace 
...
1. Activate the trace mode.
You have various options to activate the trace mode for all additional actions on the front end:
-
Call up the BEx Analyzer. Choose
Settings ®
Trace, before logging into the BI
system.
- On the Business Explorer SAP Easy Access screen, choose Business Explorer® BEx Monitor ®Trace Tool. Enter a user and choose Edit ® Activate User. You can activate all users via All Users. For more information, see OLAP Trace Tool.
To activate the trace mode for a particular query in the Web, you need to add the parameter &trace=Xto the query URL.
2. Log into the BI system and carry out the required steps.
The front-end actions are logged. The log file SAPBEX.trc is generated on the front-end computer.

Make sure that you keep the log as short as possible.
To restrict logging to important
steps, it is useful to start the BEx Analyzer without the trace at first, then
to load the workbook. Only at
this point should you interrupt the connection to the OLAP server, via
Settings, and activate the trace. You
can then create a new connection via
Refresh. The actions you subsequently carry out are now
logged.
3. Deactivate the trace mode in the same way you activated it in step 1.
You have logged actions in the front end. The logs and the OLAP trace number can be found in the OLAP Trace Tool.
When making contact with SAP support, your customer message can contain the technical name (from the InfoCube or query) as well as the number of the OLAP Trace (Log Number) in addition to the user, and the date and time the log was created.
