Schedule a pgm in background using function modules from same program

Former Member — Wed, 11 Jun 2008 18:05:07 GMT

Hi Guys,

How to schedule a program in background(using function modules) from same program itself.

When click 'execute' button in report, it should schedule same program in background.

As per my knowledge, this will create an infinite loop if we schedule it normally from same program. How we can restrict the program to schedule it only once.

Hope you guys have already faced the same..

Pls help...

Regards,

Saj

Yes definatly it will create infinite loop unless you set some variables ... and check them when you submit the program.

Like:


PARAMETERS: P_RUN AS CHECKBOX.  " when it is on, it will create a job

start-of-selection.
IF P_RUN = 'X'.

* call funcation JOB_OPEN

  SUBMIT <PROG>  "WITHOUT P_RUN = 'X'
   with jobname jobcount

* call function JOB_CLOSE

ENDIF.

You can use SY-BATCH to differentiate between your First Call and the Rest of the Calls.

Since you will call the Program in Foreground for the First time SY-BATCH will be initial and the Report will be scheduled in Background.

Now the Scheduled Report (Background) , will inturn check for the field SY-BATCH. Since SY-BATCH will be filled this time, your code of Submit Via Job will be skipped. So there will be no Recurrsion in the code.
