Slow process of ABAP code

Dear gurus

My this codes take to much time to execute.

How to resolve it ?.

Hi,

I find there is nothing to be done regarding the BAPI calls.

But, I think you should rewrite your UPDATE statement (especially because of the "nested SELECT"). I would rather process all entries in internal table using large SELECT (if required with working internal tables) and update the whole Z-table in one-pass.

Best regards,

Guillaume

Why 2 times CALL FUNCTION 'BAPI_GOODSMVT_CREATE' ?

Once is enough.

Hi,

Point 1:

Please check the code. You are reading RETURN table with TYPE = 'E' and if sy-subrc is not initial (i.e; BAPI fails) again you are calling the BAPI with the same data.

Point 2:

In the loop you are updating the DB table which will impact the performance. Avoid update in loop.

Regarding 1.: If it's not initial, then he didn't find a E message and thus it was ok.

Regarding 2: update inside a loop is not per definition wrong. It's the inner select on MSEG that's causing a sequential read

[RaymondGiuseppi]

1) The first call with test flag is not actually required, perform the call without test, and use a BAPI_TRANSACTION_ROLLBACK when an error is raised.

2) Do you actually need the "IN ( select MBLNR from MSEG WHERE werks =

wa_itab_final-plant AND charg = wa_itab_final-charg )." clause, check for MSEG indexes and other code to perform. (use SE30, ST05) - only werks and charg can give huge result/cpu without MATNR field
