Make rows as non editable in ALV

Hi Experts,

I have a standard ALV table where records are fetched from backend table. Here I have a field Approved as check box.

My requirement is I need to make all the rows as non editable, if the Approved checkbox is checked. How can I achieve this.

I went through the below discussion, but still am not clear of how to achieve it.

How to set some rows in ALV to be editable or some non editable.

I know to set a field as non editable in WD, but don't know how to set some specific rows as non editable in alv.

Please help me.

With Regards,
