• What is the cause and solution for SAP error message SADL_EXPOSURE055 - Base view &1 of &2 must not be consumption view, annotation @&3 ?

  The SAP error message SADL_EXPOSURE055 indicates that there is an issue with the definition of a base view in the context of the SAP Data Access Layer (SADL). Specifically, it states that the base view you are trying to expose as a consumption view is not allowed to be a consumption view itself. This typically occurs when you are trying to expose a view that is already defined as a consumption view, which is not permitted.
  Cause:
  
  Incorrect View Type: The base view you are trying to expose is defined as a consumption view, which is not allowed. In SAP, a base view should be a data source that can be used to create consumption views, but it cannot itself be a consumption view.
  Annotation Misconfiguration: The annotations in the view definition may not be correctly set, leading to the system interpreting the view as a consumption view.
  
  Solution:
  
  Check View Definition: Review the definition of the base view (&1) and ensure that it is not defined as a consumption view. You can do this by checking the annotations in the view definition.
  Modify Annotations: If the base view is incorrectly annotated, you may need to remove or modify the annotations that classify it as a consumption view.
  Create a New Base View: If necessary, create a new base view that is not defined as a consumption view and use that for your exposure.
  Consult Documentation: Refer to the SAP documentation for SADL and the specific annotations to ensure that you are using the correct definitions and configurations.
  
  Related Information:
  
  SAP Data Access Layer (SADL): This is a framework that allows you to expose data models as OData services. Understanding how base views and consumption views work within this framework is crucial.
  Annotations: Familiarize yourself with the various annotations used in SAP CDS views, especially those related to consumption and exposure.
  SAP Community and Notes: Check the SAP Community forums and SAP Notes for similar issues and solutions provided by other users or SAP support.
  
  By addressing the view definition and ensuring that the base view is correctly configured, you should be able to resolve the SADL_EXPOSURE055 error.
