Displaying ALV Grid in Background Job
Author: Prashant Patil
Original: https: //www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/5898

Many a times there is a requirement to display ALV Grid (not ALV List) in the background Job. I have checked the SDN Forum for the same and it has been mentioned that ALV Grid cannot be displayed in Background, but the list output of ALV is possible. So user won’t have the actual Grid interface but the List interface.

There is a workaround to display ALV Grid in Background Job. The only restriction is you can’t schedule the job through SM36. You need to execute the transaction of the report program, fill in the selection screen data and hit Execute.

The job would be executed in background. User will be able to see the Job Log and Job Status after executing the program. User doesn’t have to go to SM37 to view the job status/log. Once the Job Status is changed to “COMPLETED”, user can click on “DISPLAY SPOOL” to view the ALV Grid.

Limitations:
1. Can’t schedulea background job
2. The session should be active until the background job is completed. If the session is closed, then user won’t be able to check the output in ALV Grid. User would be able to check the output through spool or SM37

Advantages:
1. If the spool width is greater than 255 characters, then the entire width could be seen in the output because the output is directed to an ALV Grid and not to spool
2. Interface of ALV Grid is available instead of ALV List even though it’s a background job.
3. Program won’t give the TIME OUT error

Steps Required:
1. Once you execute the program, the following screen would be displayed


2. Click “Display Job Status” to check the Status of the Background Job


3. Click on “Display the Job Log” to check the Log


4. Click on “Display Job Status” to check the Job Status


5. Click on “DISPLAY SPOOL” to check the spool content once the Job Status is changed to “COMPLETED”. Output is displayed in ALV Grid


Programs:
1. Two different programs needs to be created

ZPROGRAM_ONE: This is the 1st program, where the selection screen and all the data validations would be done. Error handling for invalid data should be done in this program.

Once the data validation is done, this program would call the 2nd program ZPROGEAM_TWO. Build the logic to display ALV Grid in this program. The logic will only display ALV in foreground and it won’t be reflected in the spool.

ZPROGRAM_TWO: This program would fetch all the data and do all the processing. If you want the spool output along with ALV Grid output, then build the logic in this program to display ALV Grid.

Code:
