Background Processing & Update Task

[Former Member]

Are "background processing" and "update task" processing the same? I have a function which is timing out and I need to have it run in the background. If I used the CALL FUNCTION <name> IN UPDATE TASK, would that provide the same resource level and time allowance as having the logic run via a SUBMIT?

Hi,

no, they are not same. The update techniques are described [here|http://help.sap.com/saphelp_nw04/helpdata/en/41/7af4cba79e11d1950f0000e82de14a/frameset.htm]. You can call FM in background task directly using RFC.Have a look at ABAP documentation for calling RFC functions.

The ABAP documentation for calling RFC functions states: "Note that your RFC calls with CALL FUNCTION are processed in work processes of type DIALOG." This doesn't sound like it will address the time-out issue.

Yeap, it looks like you are right. I got confused by option BACKGROUND TASK.

Hi,

This is the F1 documentation for calling a FM in Update task

Flags the function module func for execution in the update task. It is not executed at once, but the data passed with EXPORTING or TABLES is placed in a database table and a subsequent COMMIT WORK then causes the function module to be executed by the update task.

This is the F1 documentation for calling a FM in background task

Flags the function module func to be run asynchronously. That is, it is not executed at once. Instead, the data passed using EXPORTING or TABLES is placed in a database table and the next COMMIT WORK executes it in another work process.

Hope this helps

Regards,

Call function in Background Task and set the Flag = 'X' in the FM .

After calling FM use the satetment

WAIT UNTIL FLag = 'X' UP TO 5 SECONDS.

If sy-subrc = 0.

SUBMIT RSBDCSUB....

endif.

I went with creating a new program to be run in a background process to call the function.
