ALV OO dynamic

[Former Member]

Good,

could somebody tell me how I could make a dynamic ALV Object Oriented dynamic.

It is not known how many columns are displayed in a fixed manner.

I have done ALV OO, but not dynamic.

If someone could say something. Please.

Ideally, some code, so if you show me a link to it, perfect.

Thanks

Hello Jonnatan,

Dynamic alv is given as an example in the below link....

saptechnical-->Tutorials>ALV-->ALVMainPage

where "/" stands for "/".

you could also get more help on all kinds of alv in the above site

use ".com" after saptechnical

THanks ,

Also look (and use search tool) in sdn wiki

- [Dynamic Internal Table |http://wiki.sdn.sap.com/wiki/display/Snippets/DynamicInternalTable]

- [How to create dynamic internal table structure on the basis of dynamic ALV layout change at run time. |http://wiki.sdn.sap.com/wiki/display/Snippets/HowtocreatedynamicinternaltablestructureonthebasisofdynamicALVlayoutchangeatrun+time.]

Thanks a lot.

I have used this code:
