What causes this issue?

A foreign key which previously existed is deleted. This can have the

The key of the value table was changed structurally, i.e. the positions
and/or the number of key fields changed (type or length changes without
changing the position or the number of key fields do not cause foreign
keys to be deleted).
The value table was removed from the domain of the check field.
Another domain was entered for the data element of the check field.
The foreign key was purposely deleted from the ABAP/4 Dictionary.

How to fix this error?

If the foreign key was automatically deleted and you do not want this,
then you will have to create the foreign key again.
It might be necessary to adjust the field definitions of the dependent
table to the new value table.
