• What is the cause and solution for SAP error message SADL_GEN_DRFT_MSG051 - CDS-View &1 is not VDM.viewType #BASIC ?

  The SAP error message SADL_GEN_DRFT_MSG051 indicates that there is an issue with a Core Data Services (CDS) view in the context of the SAP ABAP programming model. Specifically, the error states that the CDS view you are trying to use is not of the expected view type, which in this case is VDM.viewType #BASIC.
  Cause:
  This error typically occurs when:
  
  The CDS view you are trying to access is not defined as a basic view (VDM.viewType #BASIC). It might be defined as a different type of view, such as a composite view or a projection view.
  The view is not properly annotated or does not meet the requirements for being treated as a basic view in the context of the SAP Business Application Studio or the ABAP programming model.
  There may be a mismatch in the expected structure or annotations of the CDS view.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the CDS View Definition:
  
  Open the CDS view in the ABAP Development Tools (ADT) or the relevant development environment.
  Verify that the view is defined with the correct annotations and is intended to be a basic view.
  
  
  
  Review Annotations:
  
  Ensure that the CDS view has the necessary annotations for it to be recognized as a basic view. For example, it should have the @VDM.viewType: #BASIC annotation.
  If the view is intended to be a basic view, add the appropriate annotation if it is missing.
  
  
  
  Check View Type:
  
  If the view is intentionally a different type (e.g., a composite view), you may need to adjust your code or logic to use a different view that is of type BASIC.
  
  
  
  Rebuild and Activate:
  
  After making any changes, make sure to activate the CDS view and any dependent objects. Sometimes, changes may not take effect until the objects are reactivated.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for Core Data Services and the ABAP programming model to ensure that you are following best practices and guidelines for defining CDS views.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no dependencies or references to other views that might be causing the issue. Sometimes, the problem may stem from a related view that is not correctly defined.

  VDM (Virtual Data Model): The Virtual Data Model is a set of guidelines and best practices for creating CDS views in SAP. It categorizes views into different types, such as basic, composite, and consumption views.
  SAP Notes and Community: If the issue persists, consider checking SAP Notes or the SAP Community for similar issues and solutions shared by other developers.
  
  By following these steps, you should be able to identify the cause of the error and implement the necessary changes to resolve it.
