OOPS ALV : Cannot change initial cell which is editable

Hello Experts,

I am using OOPS to display an ALV. It has 1 column (POSTP) - CHAR(1) editable.

The problem is when the ALV is displayed, and the user clicks on POSTP to change it, he cannot change it without pressing Backspace/Delete button. (i.e. The field is not selected, The cursor is at the beginning of the field)

Important : After moving to the next field, the next field is highlighted, and the user can directly change it without pressing any other button.

I have tried changing the field-cat/layout values, but it didn't work.

Is there a way to explicitly highlight the field after ALV is displayed

Any help is appreciated.

Kind Regards,
