ALV display using OOPS method

Former Member — Wed, 05 Mar 2008 11:44:56 GMT

For displaying ALV we are using oops method .

for this method we need to fix size of container in screen

When user changes screen resolution user wont get fullscreen display

for ALV.

To overcome this problem if we design a screen using maximum screen

size. Then scrollbar dosnt work for all resolution

Steps for the Reconstruction

1 For resolution 1024 x 768 design Full screen ALV container

User will get fullscreen display

2. Now change resolution 1280 x 1024 display same alv report.

Report dosnt utilize full screen

3. For resolution 1280 x 1024 design full screen container.

display ALV report in this container. It will work perfect

for 1208 x 1024

4. Now change resolution back to 1024 x 768

ALV will display in full screen but scroll bar dosnt scroll till

last column

Please let me know if you have any suggestions to have full screen ALV container for all screen resolutions.

FALSE.

If you need a container then define it as resizable in the screen painter.

If you do not require a container because the only screen element is the ALV grid which should cover the entire dynpro then I always use a docking container and set its extension value extremely high (99999). The docking container is then linked to the empty dynrpo (see sample report ZUS_SDN_ALV_FULLSCREEN ).

Hi Uwe,

Thanks for your reply. I used docking container and i get the desired result in different screen resolution. I had 2 more questions:

1. Is docking container generally used for background transactions? or it can be used for frontend also.

2. We are facing issues for subtotals, is it not possible to use sort functionality with subtotals if we use docking containers?

Thanks

Sameer
