Hola Jarpi, tu problema se soluciona simplemente añadiendo las líneas:

CALL TRANSACTION 'FB01' USING it_bdc MODE modo.

CLEAR it_bdc[].
Refresh: it_bdc[].


ANTES de cerrar el loop, así el índice de la cabecera aumentara y mandarás todos los datos de tu tabla a la transacción FB01.

LOOP AT it_tabla.
