How could i change the label text of the standard text in custom report.

Hi,

I need a small suggestions.

In my Selection screen i put one field as sales order, When ever user click on That f4_help i need to show No of sale orders and customer name i need to add in the f4_help.

But right now data is showing like, Sale order and Name1.

But i need customer name in place of Name1. How could i changes it. If i take field as Customername(35) type c.

It's not working. Without changing the standard label can i show the result.

TYPES: BEGIN OF  ST_VBAK,

        VBELN TYPE VBAK-VBELN,

*       CUSTOMERNAME(35) TYPE C,

*       KUNNR TYPE VBAK-KUNNR,

        NAME11 TYPE KNA1-NAME1,

        END OF ST_VBAK.

DATA: IT_TVBAK TYPE TABLE OF ST_VBAK,

       WA_TVBAK TYPE ST_VBAK.

SELECT  VBAK~VBELN KNA1~NAME1 AS CUSTOMERNAME  FROM VBAK INNER JOIN KNA1 ON VBAK~KUNNR = KNA1~KUNNR  INTO TABLE IT_TVBAK.
