ABAP Trace - How To ST12

Former Member — Wed, 03 Mar 2010 14:12:19 GMT

Hi gurus,

I've red two very useful blogs about how to use ST05 and SE30 Trace Tools:

/people/siegfried.boes/blog/2007/11/13/the-abap-runtime-trace-se30--quick-and-easy

/people/siegfried.boes/blog/2007/09/05/the-sql-trace-st05-150-quick-and-easy

Thanks Siegfried, this is a great help!

I was wondering, if there's something similar describing how to use ST12. I'm struggeling to find a stream line, some kind of handy HowTo - Document for this transaction.

As a SAP BI consultant, I need to figure out some bottlenecks in a function module, that's used by a so called virtual InfoCube based on Functional Module. I tried ST12 and got some results. Unfortunately, they are very different from what the RSRT debugging tool is providing, especially in comparing ABAP Time and DB Time.

Thanks in advance!

Cheers!

Neven

you can start reading here, there is some information available (more is planned):

you should be able to open the abap trace taken with ST12 in SE30 (go to the application server where the trace was recorded and check the trace files there) Check the STAD record as well...

Kind regards,

Hermann

thanks Thomas,

at a first glance it seems to be the initial help I needed!

Thanks Hermann, your answer is apreciated! OSS Note 755977 is helpful. However, I was looking for an introduction like in your blogs. I'm only missing the "TASKS & HTTP" Button now.

Cheers!

I'm busy working on that...

well, I've overseen the links on the right, my bad! It might be some comfort, that I've ordered that ABAP Performance Tuning Book today.

Still waiting for your "Tasks & HTTP" Button usage blog ;-).

Cheers!

the ST12 is actually only a transaction on top of SE30 and ST05, it uses the basic tool internally.

The functionality in the SE30 is the USER/SERVICE button, which I did not cover in the basic approach.

But somebody else wrote already a blog on it, see

/people/olga.dolinskaja/blog/2009/12/11/abap-runtime-analysis-se30--how-to-analyze-abap-program-flow

It is further down. Same holds 1:1 for ST12. The nice features of the ST12 are the callstack approximations

of the ST12. The ST12 is nice tool, but not in the SAP standard, therefore only available on demand.
