• What is the cause and solution for SAP error message SADL_ENTITY_RUNTIME024 - Association &1 of view &2 is not available in the exposed data model ?

  The SAP error message SADL_ENTITY_RUNTIME024 indicates that there is an issue with an association in a data model that is being used in a Service Layer or OData service. Specifically, the error states that the association &1 of the view &2 is not available in the exposed data model. This typically occurs in the context of SAP Gateway or when working with the SAP ABAP programming model for SAP Fiori applications.
  Cause:
  
  
  Missing Association: The association defined in the CDS (Core Data Services) view is not included in the data model that is being exposed. This can happen if the association is not properly defined or if it has been excluded from the exposure settings.
  
  
  Incorrect Annotations: The annotations in the CDS view may not be correctly set up to expose the association. For example, the @OData.association annotation might be missing or incorrectly defined.
  
  
  View Activation Issues: The CDS view or the associated views may not be activated properly, leading to inconsistencies in the data model.
  
  
  Changes in Data Model: If there have been recent changes to the data model, such as renaming or removing associations, the service might still be referencing the old structure.
  
  
  Solution:
  
  
  Check CDS View Definition: Review the CDS view definition to ensure that the association is correctly defined and that it is intended to be exposed. Make sure that the association is included in the @OData.publish annotation.
  
  
  Update Annotations: Ensure that the necessary annotations for exposing the association are present. For example:
  @OData.association: { ... }
  
  
  Activate the CDS View: If there are any changes made to the CDS view or its associated views, make sure to activate them. You can do this in the ABAP Development Tools (ADT) or in the SAP GUI.
  
  
  Check Service Definition: If you are using an OData service, check the service definition in the SAP Gateway Service Builder (transaction code SEGW) to ensure that the association is included in the service.
  
  
  Regenerate the Service: If the service definition has changed, regenerate the service to ensure that it reflects the latest changes in the data model.
  
  
  Test the Service: After making the necessary changes, test the OData service to ensure that the association is now available and functioning as expected.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for Core Data Services and OData services for detailed information on how to define and expose associations.
  SAP Community: The SAP Community forums can be a valuable resource for troubleshooting specific issues and finding solutions shared by other developers.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11 (Data Dictionary), SE80 (Object Navigator), and SEGW (Gateway Service Builder) for managing and troubleshooting data models and services.
  
  By following these steps, you should be able to resolve the SADL_ENTITY_RUNTIME024 error and ensure that your associations are correctly exposed in the data model.
