¿Qué causa este problema?

For creation and processing of the object, key fields must not be
initial. The configuration tool prevents you from closing the window
because you have declared a key field as 'Invisible' without filling the
field by means of a formula. Therefore, the key field would always be
'initial'.

¿Cómo arreglar este error?

Assign a value to the key field declared as <LS>Invisible</> using a
formula at the time of creation (intialise or complete).
