Create a Variant for the Program and

Schedule JOB in background:

Go to SM36 create a Job

click on Start Condition

Click on DATE and TIME enter date scheduled Start and END times

click on Period Values

Click on HOURLY/WEEKLY etc

CLick on RESTRICTIONS also to use further criteria.

so your job will be scheduled and run as per your requirement.

and in SM37 Transaction check the status of that JOB

Check this link for scheduling jobs..

Hi Vamsi,

<b>First Check in the Foreground your program is working for the application server file or not</b>

When you will Execute your program in Background internal table "ZPERNR" will be populated from the file that is there on the application server.

After that what you want to do with the internal table.I think you have not sent the whole code.

In background FM GUI_UPLOAD willl not work.

If you want to debug your code put wait for 100 seconds at the place where you want to dubug your code.Go to transaction code SM50 your job will be running there.

Select Your job

Go to Menu Bar Program/Mode - > program - > Debugging.

In this way you can debug your code.

First Check in the Foreground your program is working for the application server file or not

I could not make out what are you doing with the contents of in_file?

In other words, how do you conclude that this prg is not working in background.?

You can not use gui functionality in batch programs cause there is no gui. You have to choose another place for your files and access them via open statement or with ftp functionality,
