Error en ALV

[dfma59]

Tengo el sigiente problema:
cuando corro el reporte me imprime la cabecera con sus posiciones , pero cuando le doy alguno de los botones de la barra de sap como el back,el cancelar y el finalizar me duplica las colunmas de la cabecera.

es un reporte de RH.

El codigo es el siguiente:

si alguien pudiera ayudarme.

No entiendo bien tu problema.... si pulsas exit, back o cancelar, por qué te preocupa que se duplique la cabecera?
De todas formas tu problema se debe a que debes refrescar el ALV despues de cada selección o modificación en los datos.
