How To Fix ESH_OM_OBJ_MODEL_RP2322 - Reverse/source cardinality "&3" does not fit to foreign key definitions

ESH_OM_OBJ_MODEL_RP2322 - Overview

• Message type: E = Error

• Message class: ESH_OM_OBJ_MODEL_RP2 - Object Model Repository (2)

• Message number: 322

• Message text: Reverse/source cardinality "&3" does not fit to foreign key definitions

What causes this issue?

All key fields of node &v2& of object type &v1& are specified in the
foreign key definition of the composition.
Join operators other than = are currently not supported in search. So
although at least one join operator is not =, only a cardinality
"Exactly one" or "Up to one" makes sense in search.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

In the modeler for search and analytics adjust the reverse cardinality
or the foreign key definition.
When importing data adjust the source cardinality or the foreign key
definition.
