FM REUSE_ALV_GRID_DISPLAY can't capture check box

[calvinkarlo]

Hi ,

My Requirement: I need to display an ALV grid report along with checkboxes. Further, I need to provide an option wherein the user can checkboxes and select the records that I need to process.

The problem is that I am not able to capture the ticked checkboxes. This means that I am not able to capture which of the records have been selected by the user.

I am not using Object Oriented ALV.
