Background Job

Former Member — Thu, 22 Apr 2004 06:37:46 GMT

Hi,

Lets say I am executing a report program. Now I would like to start a Background Job, which should start once this internal session is complete, is there any means of achieving the same.

Like in this case once the report is done, it should start executing the background job.

Regards,

Pavan

What is it you want to run as a background job, a report?

Hi Pavan,

Possibly you can set the background job to start after an event is triggered. You can Raise the event from your program. The job will be started when this event is triggered.

Hi Thathagata,

Unfortunately I cannot use raise event.

Hi Pavan,

In such a scenario possibly you can configure the two reports as two steps of the job. Completion of Step 1 would lead to Step 2. Just try configuring such a job in SM36.

Possibly this could solve your problem.

Hi Martin,

Thanks a lot for your reply.

But report one is executed online, by the user. The scenario is as such, User is executing some program, which locks particular entries.

Now I need to execute the subsequent report immediately the first program ends, so that the locks are not acquired by someone else, and the second program has to run only after the first program ends.

Regards,

Pavan

Hi Pavan,

are the programs Z-reports? Then you could lock the objects by yourself and start the second report in the first.

Otherwise you could use submit-statements for calling standard reports in a selfwritten program.

Martin

If both programs are Z reports then you could simply use the SUBMIT statement at the end of the first report.

Otherwise if the first one is an SAP report then one way to do it would be to create a wrapper report, by this i mean a report that will have the same selection screen(copy sap program) as the SAP report for the user to enter his/her details into. The report then calls the SAP report using the user selection then imediatly calls the zreport. Only down side would be that the user would have to execute a different transaction than they may be used to(i.e. that associated to the wrapper report).

Hope this helps

regards

Mart

Actually the work arounds are fine guys. I am completely happy with the work arounds, in fact we have also achieved a work around, using lock objects as indicated by martin.

But what exactly i am looking for was, just like we could schedule a batch job on termination of another job. Is there some way we can identify the current session as well, and say that on the termination of this session start the next one.

Pavan
