How To Fix ESH_OM_OBJ_MODEL_RP2325 - Cardinality "&3" does not fit to foreign key definitions

ESH_OM_OBJ_MODEL_RP2325 - Overview

• Message type: E = Error

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

• Message number: 325

• Message text: 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 association.
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?

Adjust the cardinality or the foreign key definition if necessary.

• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_RP2325 - Cardinality "&3" does not fit to foreign key definitions ?

  The SAP error message ESH_OM_OBJ_MODEL_RP2325 indicates a problem with the cardinality of a relationship in the object model, specifically that the cardinality defined does not match the foreign key definitions in the database. This typically occurs in the context of the SAP Enterprise Search (SAP ESH) or when working with the Object Model in SAP.
  
  Cause:
  
  Mismatch in Cardinality: The cardinality defined in the object model does not align with the foreign key constraints in the underlying database tables. For example, if the object model defines a one-to-many relationship but the foreign key in the database only allows for a one-to-one relationship, this error will occur.
  Incorrect Configuration: There may be an error in the configuration of the object model, where the relationships between entities are not correctly defined.
  Changes in Database Schema: If there have been recent changes to the database schema (like adding or modifying foreign keys), the object model may not
