How To Fix ESH_OM_OBJ_MODEL_RP2703 - Cardinality "&3" does not fit to foreign key definitions

ESH_OM_OBJ_MODEL_RP2703 - Overview

• Message type: E = Error

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

• Message number: 703

• Message text: 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 association
Thus maybe the 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?

Adjust the cardinality or the foreign key definition.

ESH_OM_OBJ_MODEL_RP2703 - Details

• The SAP error message ESH_OM_OBJ_MODEL_RP2703 indicates a problem 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 the 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 cardinality defined in the foreign key constraints. Cardinality refers to the number of instances of one entity that can or must be associated with instances of another entity. Common cardinalities include:
  
  One-to-One (1:1)
  One-to-Many (1:N)
  Many-to-One (N:1)
  Many-to-Many (N:N)
  
  In this case, the cardinality "&3" does not align with what is defined in the foreign key constraints, which could be due to:
  
  Incorrect Foreign Key Definition: The foreign key relationship may not be defined correctly in the database schema.
  Modeling Errors: There may be errors in the data model
