• What is the cause and solution for SAP error message /IWBEP/CM_V4_RUNTIME015 - Resolving of navigation not possible - more than one target key provided ?

  The SAP error message /IWBEP/CM_V4_RUNTIME015 indicates that there is an issue with the navigation in an OData service where more than one target key is provided for a navigation property. This typically occurs when the OData service is trying to resolve a navigation path, but the system encounters multiple keys that could potentially match the target entity, leading to ambiguity.
  Cause:
  
  Ambiguous Navigation: The navigation property in the OData service is defined in such a way that it can point to multiple entities, but the request does not specify which one to use.
  Incorrect Entity Relationships: The relationships between entities may not be correctly defined, leading to multiple possible targets for a navigation property.
  Data Model Issues: The underlying data model may have issues, such as duplicate keys or incorrect associations.
  
  Solution:
  
  Check Navigation Properties: Review the OData service definition and ensure that the navigation properties are correctly defined. Make sure that each navigation property has a clear and unambiguous target.
  Review Entity Relationships: Verify the relationships between entities in the data model. Ensure that the associations are correctly defined and that there are no duplicate keys or ambiguous relationships.
  Modify the Request: If the request is being made programmatically, ensure that it specifies the correct key for the target entity. If multiple keys are being sent, modify the request to include only the relevant key.
  Debugging: Use transaction codes like /IWFND/ERROR_LOG to check for additional error details or logs that can provide more context about the issue.
  Update OData Service: If necessary, update the OData service to handle the navigation more effectively, possibly by adding filters or modifying the service definition to clarify the navigation paths.
