Why do you use the I[N BACKGROUND TASK|http://help.sap.com/abapdocu_70/en/ABAPCALL_FUNCTION_BACKGROUND_TASK.htm] option (start after commit) and not a simpler [STARTING NEW TASK|http://help.sap.com/abapdocu_70/en/ABAPCALL_FUNCTION_STARTING.htm] task

Nevertheless, check via SM59 there are options on destination (default NONE) (in menu) to manage the RSARFCSE report (which contain the call to the FG you mentioned) (number of call, delay, etc.)

Raymond

Hi,

Create a programa to call the FM and put it on a job, or execute the programa in background..

As says "Create a programa to call the FM and put it on a job, or execute the programa in background"

I can't use any program for process FM in BKG job....

Create a report program, call your FM in this report....and execute this report in the background (or through a scheduled job).

does it not work for you?

You cannot call an RFC in a BG work process.

RFC always executes via a Dialog work process. The addition IN BACKGROUND TASK doesn't facilitate the RFC to be executed in a BG process. Read the documentation thoroughly.

Anyways can you elaborate what's your requirement & why you want the RFC to be executed in BG mode ?

Thanks suhas for your reply,

But as per below link we can process RFC in background job..

http://help.sap.com/saphelp_nw04/helpdata/EN/22/042585488911d189490000e829fbbd/frameset.htm

but my concern is other....as it's occupying both dialog and backgroud work process.

Can any one elaborate on background processing in context of my requirement?

Hi Anuj,

I tried the same scenario here, and below are my comments.

1. When we call the RFC FM in Background Task, then it will occupy DIALOG work process, and not background work process.

2. The second process which you are seeing, i.e. SAPLERFC, that is required by the server to start the RFC. however, this gets displayed only for some time (to start the background task), after that it disappears.

Thanks Amit for your findings...

But i want to ask what does background task means..

Either it means to start FM in a particular time in Dialog work process OR it means to start FM in a particular time in only BACKground work process.

Anuj jain.

Hi Anuj,

It unfortunately means:

start FM in a particular time in Dialog work process

The BACKGROUND word in abap syntax is misleading.

For true background processing, i.e. background WORK PROCESS (of type BGD in SM50)

ONLY ABAP PROGRAMS or Commands or External Programs

can be run under background work process. (as per SM36)

Here we are trying a function module, which is not supported. This is as per my understanding.

amit m.

RFCs always use dialog work process, that's the golden rule for RFCs

BACKGROUND TASK is kind of misnomer. This is used to implement the tRFC (transactional RFC) model. If you read the SAP documentation it's very well documented.

Anyway thanks to Amit n suhas for their valuble time.

Thanks Amit and Suhas for your support ....

Now i'm sure that we can't process Any RFC directlly in background work process but can i process any FM (not RFC) in background work process ...like

calling FM inside RFC and call that FM in background work process.

Call RFC in diallog

function.

call function FM(nt RFC) in background

endfunction.

will it work????? .....

Hi again,

As per my understanding we cannot do that, even though the FM is normal and not RFC enabled.

Below are my comments.

1. FMs can be CALLED synchronously or asynchronously ONLY. There is no option of background work process. It will work only with dialog work process.

2. For background work process, we NECESSARILY have to use a SEPARATE Z PROGRAM, and inside that call the FM.

3. We can BACKGROUND a Z Program, not the FM.

Hope this helps.

Amit Mittal.

Hi Anuj;

I got some infomation on the background processing of RFM.

From your calling statement, it belongs to transacational RFM calling.

Call Function rfm_name

in background task

...

you need to write a 'Commit work' after a serial of such calling which are in same LUW. And only after the statement, the LUM willl start its background processing in the target system. But note that, it does not allowed interactive dialog processing with target system and debugging..

Hope this help you..

"you need to write a 'Commit work' after a serial of such calling which are in same LUW. And only after the statement, the LUM willl start its background processing in the target system. But note that, it does not allowed interactive dialog processing with target system and debugging"

i'm already using commit work in my code...but RFM nt working in background
