• What is the cause and solution for SAP error message /IWBEP/SBOD351 - Dependent Property &1 for referential constraint must not be complex type ?

  The SAP error message /IWBEP/SBOD351 indicates that there is an issue with a dependent property in a referential constraint within your OData service. Specifically, it states that the dependent property must not be of a complex type. This error typically arises when you are trying to define a relationship between entities in your OData model, and one of the properties involved in the referential integrity constraint is incorrectly defined as a complex type.
  Cause:
  
  Complex Type Definition: In OData, a complex type is a type that can contain multiple properties and is not a simple scalar value (like string, integer, etc.). If you are trying to use a complex type as a dependent property in a referential constraint, it will lead to this error.
  Incorrect Model Configuration: The error may also arise from incorrect configuration of the entity types and their relationships in the data model.
  
  Solution:
  
  Check Entity Definitions: Review the definitions of the entities involved in the referential constraint. Ensure that the dependent property is defined as a simple type (e.g., string, integer) and not as a complex type.
  Modify the Data Model: If the dependent property is indeed a complex type, consider changing it to a simple type or restructuring your data model to avoid using complex types in referential constraints.
  Update the OData Service: After making the necessary changes to the entity definitions, regenerate the OData service and check if the error persists.
  Referential Constraints: Ensure that the referential constraints are correctly defined. A dependent property should reference a key property of the principal entity, which should also be a simple type.
  
  Related Information:
  
  OData Model: Familiarize yourself with the OData model and how entity types, complex types, and relationships are defined.
  SAP Documentation: Refer to the official SAP documentation for OData services and entity relationship modeling for best practices and guidelines.
  Debugging Tools: Use SAP tools like the ABAP Development Tools (ADT) or transaction codes like SE80 to inspect and modify your data model.
  
  By addressing the definition of the dependent property and ensuring it is a simple type, you should be able to resolve the error message /IWBEP/SBOD351.
