• What is the cause and solution for SAP error message SADL_EXPOSURE079 - Transactional association &1 of &2 to many is not annotated with @&3 ?

  The SAP error message SADL_EXPOSURE079 indicates that there is a problem with the annotation of a transactional association in your SAP system. This error typically arises in the context of SAP Gateway or OData services when defining associations in your data model.
  Cause:
  The error message states that a transactional association (which is a type of association that allows for operations like create, update, or delete) is not properly annotated with the required annotation. The placeholders in the message represent:
  
  &1: The name of the transactional association.
  &2: The name of the entity or data model.
  &3: The required annotation type (usually @Transactional or similar).
  
  This error usually occurs when:
  
  The transactional association is defined in the data model but lacks the necessary annotations that inform the framework how to handle it.
  The annotations are either missing or incorrectly specified in the metadata of the OData service.
  
  Solution:
  To resolve this error, you need to ensure that the transactional association is properly annotated. Here are the steps you can take:
  
  
  Check the Data Model: Review the definition of the entity and its associations in the data model. Ensure that the transactional association is defined correctly.
  
  
  Add Required Annotations: 
  
  Open the relevant CDS (Core Data Services) view or the data model where the association is defined.
  Add the required annotation to the transactional association. For example, if the annotation is @Transactional, it should be added like this:
  association [0..*] to AnotherEntity as _AnotherEntity
    on _AnotherEntity.key = AnotherEntity.key
    @Transactional
  
  
  
  
  Activate the Changes: After making the necessary changes, activate the CDS view or the data model to ensure that the changes take effect.
  
  
  Regenerate the OData Service: If you are using an OData service, regenerate the service to reflect the changes made in the data model.
  
  
  Test the Service: After making the changes and regenerating the service, test the OData service to ensure that the error is resolved.
