process chain optimization

Dear All,

Our transaction process chains have been running for 2-3 hours longer daily than a few months ago. Users are not able to have data in time.

What are programs or t-codes where we can do a comparison of a process chain on various days.

I am currently working with /ssa/bwt program but since we have about 35 sub chains (some of them huge) within our transaction chain, comparison gets difficult when objects don't run in the same order (in many cases due to failure and correction).

Idocs getting stuck, we are checking. But for a direct one by one step wise comparison on volume of data, any t-code, program?

Regards,
Cleo

    Hi Cleo ,

    Go to transaction ST13  ( Tool name : BW-TOOLS ) execute

    Select process Chain Analysis

    Please check if this satisfies your need

    Thanks ,

    Hi Cleo,

    Can you have look in to this table RSPCPROCESSLOG

    Copy instance id and log id from respective process step, right clik, display messages.enter at above table selections.

    Hi Cleo,

    make sure you have implemented all the notes/bug fixes from the following 3 'Composite SAP Notes' on your BW Landscape, including any manual steps...

    1827854 - Enqueue/Lock during parallel data loads

    2096765 - Composite note for hanging Infopackage processes in Process Chains

    2093582 - Composite note for hanging DTP processes in Process Chains

    This will significantly increase the performance of your process chains and also prevent most of the bugs associated with the failures. You can see which bug-fixes are relevant to your SP Level also.

    Please give points if this resolves your problems once you have completed your analysis via transaction ST13,

    thanks,

    Hi,

    If you just want to compare the runtimes of process chains, including sub chains, then easy thing to would be

    - run Tx ST13 (same as /SSA/BWT program)

    - provide all the required chains in selection, including all the sub chains

    - provide date range for which you want to analyze (say last 1 month)

    - execute

    - copy the columns - process chain name, log id, date of execution and runtime

    - paste into Excel and create a pivot table over that

    You can easily apply some filter or create graph to even visually check and compare run of one or more process chains with their previous runs.

    Hope this helps,
