• Message number: 184

• Message text: Clé externe &-& modifiable uniquement dans table incluse

Quelle est la cause de ce problème?

You switched in change mode to a foreign key for an included table in
name range CI_ (or SI_) or an append structure.

Réponse du système

The foreign key is only displayed. It cannot be changed.

Comment corriger cette erreur?

Only change foreign keys for such structures in the structure itself.
The change then affects the included tables as well.
In general it is possible to define the included foreign key in the
included table differently from the included table.
The special cases described above can however be seen as
application-specific or customer-specific elements of a table,
which should avoid modifying the standard table. Foreign key
maintenance in the standard table would however be a modification.
