Set focus on cell in ATS Table

Hi Friends,

I try to set the focus on a field in a if_fpm_guibb_list.

I use Methode request_focus_on_cell in if_fpm_list_ats_ext_ctrl.

And I set lead Index to new line and set selected_line _changes to 'X'.

When I look in the table what contain the new position, it contains the Data for the new position.

But the cursor is not jumping to the Cell.

Is there something in addition what I have to do?

Thanks in advance

Joerg.
