Display ALV Grid on List Generated by WRITE

By | January 18, 2017 | Tricks | 12,056 | 8

Ever wondered how to generate the ALV Grid on the list generated by WRITE statement. Lets see today how we can do that.


Many years ago I wrote an article (I used to refer them as Post, that time) on how to display the ALV on the selection screen. The idea on displaying the ALV on selection screen is simple – Get the data, create the docking container and display that on the selection screen generated by the program. Read more on that at Display ALV report output in the SAME Selection Screen

For this new way, I was researching how to apply the similar concept on the List generated by the WRITE. I should be fare here – I didn’t thought of working on this until, reader Kousik Mishra raised the question on how to achieve it.

The output is something similar to this:



I will skip the journey as I referred to the earlier post and fast forward to come to the point. The key here is to display the output on the screen generated by the list. When we use the WRITE statement, system uses the specific screen to display that list. The screen is 0120 of the program SAPMSSY0. So, while generating the docking container, I have used that to display the ALV grid.

Code Lines

Here is the complete code:

Output with ALV functions applied

Just to make sure all other functions on ALV also works

    This is another good approach to display ALVs. Additional functions such as clicking on header, highlighted texts in header etc can be achieved…

  • Kousik Misra

    Thanks a lot Naimesh. Such a quick response..
    Now i will try the same way and will let you know if i face any issue.

  • Steve Oldner

    Pretty interesting. So this is a container on the write screen? Wonder if field cat changes and events would work here also?

  • Kousik Misra

    Whoa!…everything is working fine now. Thanks a lot Naimesh.

  • @ Steve – Yes they would all work as they are on top of the “legal parent” – Docking container :)

    @ Mohit – Correct. You can either use that as Top of the page, or use the ALV to display certain logs for predefined formatted output (not created by SAPSCript but still using the old WRITE)

    @ Kousik – You welcome!

    Hi Nimesh,

    Your blogs are awesome continuously helping beginners as well as experienced a lot before going through ur articles OOPS concepts are night mare for me but now i feel quite comfortable your way of explaining concepts are very descriptive, logical and you put lot of efforts and research into it and it shows.

    *Requesting you to please come with more and more blogs covering different different SAP ABAP concepts frequently

    Thanks & Br

  • Wow.. this is interesting. Never thought of this approach earlier. Thanks for the share.

    Hi Naimesh,

    I have a requirement (Intercative Report) in that output i have to display the header and Item and when the user will select in any header row it will be display corresponding item details in the same screen down side.

    What i try. I have created the report in that it is displaying the both header and corresponding item details but in one shot there is no interactive.

    Thank & Regards,
    Rupesh Chouhan.
