Hola a todos. He realizado un pequeño programa. Le he modificado un poco los botones del ALV para que cuando le doy a 'PROCESAR' me genere un fichero. Éste es el codigo:
El problema es que en cuanto le doy al boton de GENERAR me da un error del siguiente tipo:
Err.tmpo.ejec. MOVE_TO_LIT_NOTALLOWED_NODATA
Assignment error: Overwriting a protected field.
The program tried to assign a new value to the field "<L_BOX>" even though
it is protected against changes.
La verdad es que no se que hacer...alguien se ha encontrado con lo mismo alguna vez????
Gracias!
