/SAPAPO/SDRQCR21 Performance issue

hi all,

we're facing high RFC load on backend OLTP box when a job with report /SAPAPO/SDRQCR21 is run.

ST12 trace suggests, as seen in the screenshot.

any hints ?

    Hello Kris,

    The load is actually not on OLTP box, the chunk that you highlited in your screenshot is actually on APO side. Of course, whenever your run the above program it makes an RFC call to do a comparison between R/3 and APO to correct the inconsistency. Did you try using different block size (Block Size Prod/Loc. Combin.) in the selection screen of the program ? Also, try to schedule the with multiple steps with each step being run at Plant level.

    Hope this helps.

      im not sure of ST12 trace results for RFC function calls but,

      your ST12 traces show 88% of time passed in that RAPO_SD_REQ.... function.

      So if this ST12 trace shows the details of duration of that function ( to reach a total of 845 sec) , check it (a DB access ? a loop ?, ...)

      Else (if ST12 do not show that function detailled times), maybe when tracing this, you have to activate also a trace on the remote system to get the detailled times of that function.

      You can maybe trace the user used to call the function.

      Just some ideas to help.
