Set a flag in the end of the program . and check it before executing the same thing. If it is set, exit

Hi Rajiv,

Thanks for your reply,

but i want to execute my program in the background.

so i used SUBMIT stmt to schedule background by calling job_open, job_close.

between job_open and job_close i submited the program with job name and job count.

when i open the sm37..there it is showing lot of spool requests..

what is the problem i couldn't understand..can anybody tell me.

Thanks in Advance,

Hi Venkat,

try to look at this solution:

*Prevent the program from having more   
*the one instance running the same time.
*Create this macro in TRMAC using SM31  
*Insert the following single line in the
*program right after the REPORT state-  
*ment:   

ZCHK_MYSELF_RUNNING SY-REPID.  

DATA: PRG LIKE INDX-SRTFD. 
PRG = &1  .   
CALL FUNCTION 'ENQUEUE_ESINDX'         *
     EXPORTING RELID = 'ZZ'            *
          SRTFD = PRG                  *
          SRTF2 = 0                    *
     EXCEPTIONS FOREIGN_LOCK = 1       *
           SYSTEM_FAILURE = 2          .   

IF SY-SUBRC NE 0.     
  WRITE: 'ERROR:',PRG,'is already running'.
  EXIT. 
ENDIF.    

I once found it on the web but I didn't test it yet.
