How To Fix ESH_OM_OBJ_MODEL_RP2700 - Reverse/source cardinality "&3" does not fit to foreign key definitions

ESH_OM_OBJ_MODEL_RP2700 - Overview

• Message type: E = Error

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

• Message number: 700

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

What causes this issue?

Not all key fields of node &v2& of object type &v1& are specified in the
foreign key definition of the composition or at least one foreign key
definition has the join-operator =.
Thus maybe the reverse/source cardinality "&v3&" may not make sense.

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.

• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_RP2700 - Reverse/source cardinality "&3" does not fit to foreign key definitions ?

  The SAP error message ESH_OM_OBJ_MODEL_RP2700 indicates an issue with the cardinality of a relationship in the object model, specifically related to foreign key definitions. This error typically arises in the context of the SAP Enterprise Search or SAP HANA modeling, where relationships between different entities (or tables) are defined.
  
  Cause:
  The error message suggests that there is a mismatch between the expected cardinality of a relationship and the actual foreign key definitions in the database. Cardinality refers to the number of instances of one entity that can or must be associated with each instance of another entity. The error message indicates that the reverse or source cardinality defined in the model does not align with the foreign key constraints that have been set up in the database.
  Possible Causes:
  
  Incorrect Cardinality Definition: The cardinality defined in the object model does not match the foreign key constraints in the underlying database tables.
  Modeling Errors: There may
