¿Qué causa este problema?

Every secondary table of a lock object must be connected to a base
table above it in the hierarchy by a join condition. This join
condition must be implemented by a foreign key. This foreign key must
have the secondary table as foreign key table and the base table above
it in the hierarchy as check table. No base table field may be checked
against several different key fields by the join condition (as foreign
key field).
The base table field named does not conform to this requirement.

Respuesta del sistema

Construct the hierarchy of the lock object correctly. Observe the
<DS:TX.DDDOK_ENQU_REQUIREMENTS>requirements for the join conditions of
