Hola a todos.
Tengo un reporte que me consulta las facturas generadas y me muestra la fecha de creación, el cliente, etc.
En este reporte agregue un campo editable para que el usuario ingrese la fecha en que se entrego la factura al cliente y esa fecha se guarda en una tabla Z, cuando muestro el reporte yo consulto esa tabla Z para ver si a la factura ya le agregaron la fecha de entrega y mostrarla, si no la tiene pues no muestro nada y así el usuario coloque la fecha de entrega.
La cuestion es como hago para que ese campo sea solo editable cuando la factura no tenga fecha entrega, si ya tiene fecha de entrega que no se editable.
No se si me explico 
PD: Estoy aprendiendo ABAP hace poco.
