1.Introduction
In the abap how to refresh alv internal table in the alv by click ‘x’? I will demostrate it in next example. The purpose is that add the other logic in ohter alv field.
2 Example

3 Summary
3.1 Add the code
We add it and the data can be changed.
data lw_guid type lvc_s_glay.lw_guid-edt_cll_cb = 'X'.
3.2 Take function.
The FM ' REUSE_ALV_GRID_DISPLAY ' is not use event .
3.3 Input field
As long as you input field in the alv, we will write logic in the field. Otherwrise it is empty.
