• What is the cause and solution for SAP error message SADL_EXPOSURE036 - Target entity &1 is not annotated as root entity ?

  The SAP error message SADL_EXPOSURE036 indicates that the target entity specified in your request is not annotated as a root entity in the context of the SAP Data Access Layer (SADL). This typically occurs when you are trying to expose a non-root entity in a service definition or when you are trying to access an entity that is not properly configured in the OData service.
  Cause:
  
  Entity Annotation: The target entity is not defined as a root entity in the metadata. In SAP, root entities are those that can be directly accessed via OData services.
  Service Definition: The service definition may not include the target entity as a root entity, which means it cannot be directly accessed or exposed.
  Model Configuration: There may be issues with the way the data model is configured, leading to the entity not being recognized as a root entity.
  
  Solution:
  
  
  Check Entity Annotations:
  
  Open the relevant CDS (Core Data Services) view or entity definition.
  Ensure that the target entity is annotated with @OData.draft.enabled and @OData.root if applicable. This annotation indicates that the entity can be accessed as a root entity.
  
  
  
  Modify Service Definition:
  
  If you are using a service definition (e.g., in an OData service), ensure that the target entity is included in the service definition as a root entity.
  You can do this by modifying the service definition in the SAP Gateway Service Builder (transaction code SEGW).
  
  
  
  Regenerate the Service:
  
  After making changes to the annotations or service definition, regenerate the service to ensure that the changes take effect.
  Use transaction code /IWFND/MAINT_SERVICE to register and activate the service.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no dependencies or relationships that might prevent the entity from being treated as a root entity.
  
  
  
  Testing:
  
  After making the necessary changes, test the OData service to ensure that the target entity can now be accessed without errors.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on CDS views, OData services, and SADL.
  SAP Community: Engage with the SAP Community forums for discussions and solutions related to similar issues.
  Transaction Codes:
  
  SE11: Data Dictionary to check the structure of the entity.
  SE80: Object Navigator to view and edit the CDS views.
  SEGW: Service Builder for OData service definitions.
  
  
  
  By following these steps, you should be able to resolve the SADL_EXPOSURE036 error and successfully expose the target entity as a root entity in your OData service.
