Use of Container for Application Log in ALV GRID

Hi,

I have created 2 custom containers on the screen one for 'display of data' and

the other for 'Display of error messages'.

CREATE OBJECT g_grid
    EXPORTING
      i_parent          = g_cust_cont_data       " this is data container
      i_applogparent    = g_cust_cont_log.    " this is for error messages

I am getting the data displayed properly in the upper grid, and whenever error occurs

they are shown up in the bottom grid, if there are no errors, the bottom container is invisible.

My problem is even if no error occurs then also the log container should be visible,

please sugegst me soultion.hope my question is clear.

Regards,

Sowjanya
