Scroll event - Webdynpro abap ALV

Hi Experts,

We are dealing with very large datasets - 10million records and using ALV to display it based on selection screen input.

Performance is very poor - we came to know context paging accessing data's from one of the Thomas Jung's Blog post - handling data in packets based on the scrolling of Table ui

We are planning to implement the same for Webdynpro abap ALV.

Is there any event available to capture the scrolling of ALV table or we need to use onfunction of ALV event itself.

Please help us.

Thanks

Sathish

If you have such a large dataset then don't use the ALV. You will the extra overhead of the cross component context binding to the ALV component. If you are working with such large datasets then you should certainly use the table UI element. This is also the only UI element that will allow such UI element paging.

In NetWeaver 7.02 we do implement the concept of context paging via a special supply function. Only then would such an approach be possible with the ALV.
