ALV Hierarchial

Hi,

I have a requirement like, when we click on one of the records in the grid display (first screen) I have to call a screen with 2 alv screens in the same screen. Among this 2 screens one is Hierarchial alv. I am using 'REUSE_ALV_GRID_DISPLAY' in the first screen and when double click I am calling a screen with 2 custom containers in it. For the first custom container I am using 'CL_GUI_ALV_GRID' to fill the data. Now I have to fill second container with Hierarchial alv. I have tried to find a class for hierarchial ALV. If anybody know how to do this, Please suggest me.

Thanks,

Ram
