ALV - Save Layout button -> "User-Specific" checkbox

Hi Experts,

I have a requirement to do following for a custom program:

1. The user will have the possibility to check or not “user-specific”

I have fixed this by setting parameter I_SAVE to 'A' in method SET_TABLE_FOR_FIRST_DISPLAY.

2. By default, the “user-specific” check box must be ticked.

Does anyone have a solution for the second requirement?

or Kindly advise if this request is not possible.

Thanks in Advance,

Aljay
