Help with a FM running in background task

Former Member — Thu, 29 May 2014 12:55:37 GMT

Hi guys

I have problem with FM runing in background task!!

ıts suppsed to update the table zmm_t_so_001, it works well when run without background task

I have ran FMs like BAPis in background before and it was ok

Here is the code!!

Function Module --- ZZ_TEST_BACKGROUND

function zz_test_background.

break solend.

data(lr_satinalma_header) = new zmm_t_so_001( ).

call method zcl_mm_so=>get_next_number_appid

importing

appid = lr_satinalma_header->appid.

lr_satinalma_header->belnr = value #( ).

lr_satinalma_header->kalnr = value #( ).

*Aktarım durumu Yeni

lr_satinalma_header->bstyp = value #( ).

*Aktarım durumu

lr_satinalma_header->akdur = 'YK'.

lr_satinalma_header->frgst = value #( ).

*Onay Tipi

lr_satinalma_header->ontip = value #( ).

lr_satinalma_header->ontur = value #( ).

lr_satinalma_header->erdat = sy-datum.

lr_satinalma_header->erzet = sy-uzeit.

lr_satinalma_header->ernam = sy-uname.

**Gonderim durumu

lr_satinalma_header->gondr = ' '.

**İnsert here!!

insert zmm_t_so_001 from lr_satinalma_header->*.

commit work.

endfunction.

then this Fm is called from the report here

report z_learnıng.

START-OF-SELECTION.

call FUNCTION 'ZZ_TEST_BACKGROUND'

in BACKGROUND TASK

the interesting part is it works ok when its ran without the BACKGROUND TASK

Hi Solen,

When FM in called in background task then it first registered for LUW wont execute immediately. After COMMIT WORK statement the registered FM will execute.

In your case, i not seeing commit work statement in calling program Z_learning to execute the FM.

Hi Solen,

Try and add COMMIT WORK after the CALL FUNCTION.

This will update the database and also your problem will be solved.

Hi ganesh

i also added commit after the FM but that also dint fix the issue

i was checking the remote comparison by chance i saw that there is s problem with RFC

So i come to think it might be the RFC that has problem maybe.

then just now i tried and it worked without code change

it didnt make sense to me but i guess it was RFC issue!!

thanks guys for suggections!!

Hi Solen,

As you mentioned that you are using RFC. Try

CALL FUNCTION '-----------' IN BACKGROUND TASK DESTINATION 'RFC_DEST'.

COMMIT WORK.

here keep RFC destination as your calling system itself.

May be this will solve your issue.

Interesting thing here,

1. The commit will happen automatically if the executable program completes sucessfully without runtime error.

2. if you call the FM in background its not necessary that it executes right then, it will be scheduled for execution, In my system the background job will be scheduled with the delay of 30 mins atleast in DEV. Not sure how it decides the time. Please check if the job is scheduled or not.

if yes you can change the start time

Hi Syed,

For 2 point i got a point from help,

"If the specified destination is not available when COMMIT WORK is executed, an executable program called RSARFCSE is started in background processing. By default, this tries to start the function modules registered for a SAP LUW in their destination every 15 minutes and up to 30 times. You can make changes to these parameters using transaction SM59. If the destination does not become available within the defined time, it is recorded in the database table ARFCSDATA as the entry "CPICERR". By default, this entry in database table ARFCSSTATE is deleted after eight days."

So adding destination with the background may help in getting that Job start automatically.

yah good one, i didn't know that.

but i told that the job it itself will be scheduled to start after 30 mins the start time will be +30 mins from the execution of the parent program, how that happens?
