I need to change the description from follon doc to billing documents? Can I?

SELECT vbeln FROM vbfa INTO TABLE gt_vbeln WHERE vbelv = p_so_v.



           SORT gt_vbeln.

           DELETE ADJACENT DUPLICATES FROM gt_vbeln.



      CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

        EXPORTING

          retfield               = 'P_BD_V'

         value_org              = 'S'

        TABLES

          value_tab              = gt_vbeln

         return_tab             = gt_return2

       EXCEPTIONS

         parameter_error        = 1

         no_values_found        = 2

         OTHERS                 = 3

                .



      LOOP AT gt_return2 INTO gs_return2.

      p_bd_v = gs_return2-fieldval.

      ENDLOOP.

If I do the F4 on vbeln of  vbfa, the description comes to be 'Document'. How can I change the description, Please suggest.

Regards

Mani
