Select Option Field Description?

Dear All,

I am using Select options for kunnr. I dont want sandard descrption for kunnr, (std : customer ), instead i want to use some label.

But, after using I_IS_AUTO_DESCRIPTION = abap_false also, std description is coming. How to delete/invisible std dictionary description?

Please help.

    lr_field = lv_r_helper_class->CREATE_RANGE_TABLE( 'KUNNR' ).
    lv_r_helper_class->ADD_SELECTION_FIELD(
      i_id              = 'KUNNR'
*      I_DESCRIPTION     = 'C Code'
      I_IS_AUTO_DESCRIPTION = abap_false
      i_value_help_type = if_wd_value_help_handler=>co_prefix_ovs
      I_SUGGEST_VALUES  = abap_true
      it_result         = lr_field ).

thanks,

Venkat.
