ALV grid refresh - column name change

Hi all,

I'm using function module REUSE_ALV_GRID_DISPLAY to display an ALV, where I added two buttons. Those buttons will take a specific action, that I'm managing in USER_COMMAND form, and after they will update the ALV grid.

I'm using the following code to refresh the alv grid:

rs_selfield-refresh = 'X'.
rs_selfield-col_stable = 'X'.
rs_selfield-row_stable = 'X'.

This all works fine to refresh the alv grid, but strange behaviour happens: the alv column names are changing from the data element short text to the data element long text.

Any ideas why this is happening?

Thanks in advance.

Best regards,

Sónia Gonçalves
