¿Qué causa este problema?

All tables that are inserted in a lock object have to be linked to each
other by foreign key. There are a number of restrictions for the links:
The foreign key relationships of the tables of the lock object must
form a tree. The tables are the nodes of the tree. The links of the
tree mean "are the check table for".
The foreign key fields must be key fields of the foreign key table.
The foreign key relationships defined between the base tables of the
lock object for a field of one of the base tables may be checked
against more than one other field. A field therefore may neither occur
twice as foreign key field in a relationship nor may it be checked
against two differenet fields in two different foreign key
relationships.
There is a restriction for cross-structure foreign keys. If a field is
assigned to a field lying outside the check table, the table from which
this field originates must lie in a sub-tree that has the check table
of this foreign key relationship as root.

Respuesta del sistema

Based on the defined relationships, no more tables may be added.

¿Cómo arreglar este error?

Define suitable foreign key relationships for the tables you use.
