  The SAP error message SADL_ATC_CHK_CONTEXT004 typically indicates that there is an unsupported annotation in the context of a Projection CDS (Core Data Services) view. This error often arises when certain annotations that are not compatible with the projection view are used, leading to issues in the data model or the way the data is being accessed.
  Cause
  The error can be caused by several factors, including:
  
  
  Unsupported Annotations: The Projection CDS view may contain annotations that are not allowed or not supported in the context of a projection. For example, annotations related to aggregation, grouping, or certain types of associations may not be valid in a projection view.
  
  
  Incorrect Usage of Annotations: Annotations that are valid in other types of CDS views (like Consumption views) may not be applicable in projection views.
  
  
  Modeling Errors: There may be a misunderstanding of how to properly define a projection view, leading to the inclusion of annotations that are not appropriate for the intended use case.
  
  
  Solution
  To resolve the SADL_ATC_CHK_CONTEXT004 error, consider the following steps:
  
  
  Review Annotations: Check the annotations used in your Projection CDS view. Remove or modify any annotations that are not supported in the context of a projection. Common unsupported annotations include those related to aggregation or complex associations.
  
  
  Refer to Documentation: Consult the SAP documentation for CDS views to understand which annotations are valid for projection views. The official SAP Help Portal provides detailed information on CDS annotations and their contexts.
  
  
  Simplify the View: If possible, simplify the Projection CDS view by removing complex logic or unnecessary annotations. Focus on the essential fields and their mappings.
  
  
  Use Alternative View Types: If you need to use unsupported annotations, consider using a different type of CDS view, such as a Consumption view, which may allow for more complex annotations.
  
  
  Check for Updates: Ensure that your SAP system is up to date, as newer versions may have improved support for certain annotations or features.
