¿Qué causa este problema?

The foreign key was not fully defined in the ABAP/4 Dictionary
maintainance. Full maintenance means that exactly one field from
the table to be checked is assigned to each key field in the
check table. The fields that are assigned to one another must refer to
the same domain. The field assignment must always contain the check
field (the field with which the foreign key was defined), the position
of this field being irrelevant.

El sistema emite un mensaje de error y no le permitirá continuar con esta transacción hasta que se resuelva el error.

Respuesta del sistema

The ABAP/4 Dictionary table can only be activated if the foreign key has
been defined fully.

¿Cómo arreglar este error?

When maintaining the foreign key, all key fields from the check table
must be assigned to fields from the table to be checked (foreign key
table).
