/IWBEP/SBOD431 - Details

• The SAP error message /IWBEP/SBOD431 Complex Property is not supported for Referential Constraint typically occurs in the context of SAP Gateway and OData services when there is an attempt to define a referential constraint on a complex property in an entity type. In OData, complex types are used to represent structured data, but they do not support referential integrity constraints like simple types do.
  
  Cause:
  The error arises when:
  
  You are trying to create a referential constraint (like a foreign key relationship) on a complex property within an entity.
  The OData service does not support referential constraints on complex types, as they are not designed to be linked in the same way as simple types.
  
  
  Solution:
  To resolve this error, consider the following approaches:
  
  
  Change the Data Model:
  
  If possible, modify your data model to avoid using complex properties for referential constraints. Instead, use simple properties (like primitive data types) that can be linked through foreign keys.
