ALV OM: how to rename exception column?

Hi gurus,

please help me with the following issue: I can't rename exception column.

Here is my code:

lr_columns->set_exception_column( value = 'USAGE' ).
lr_column ?= lr_columns->get_column( 'USAGE' ).
lr_column->set_short_text( 'Usage' ).
lr_column->set_medium_text( 'Usage' ).
lr_column->set_long_text( 'Usage' ).

but the alv still show 'Exception':

Regards, Maria
