REUSE_ALV_VARIANT_DEFAULT_GET

You will have layouts saved with your ALV Grid / List. This function module will return the layout name which is marked as default for the ALV list / grid.

REUSE_ALV_VARIANT_F4

This function will show a pop up with the list of layout associated with a ALV grid / list. The user can select any one from the list.

Ravi
