  The SAP error message SD_CDS_PROJECTION002 typically occurs in the context of Core Data Services (CDS) views in SAP S/4HANA, particularly when dealing with annotations related to projections. This error indicates that the value of a specific annotation is not set correctly, and it must be either #PROJECTION_LIST or #NONE.
  Cause:
  The error is caused by an incorrect or missing configuration in the CDS view definition, specifically related to the projection annotations. The projection annotations are used to define how data is selected and presented in the CDS view. If the annotation value is not set to one of the expected values (#PROJECTION_LIST or #NONE), the system will throw this error.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the CDS View Definition:
  
  Open the CDS view in the ABAP Development Tools (ADT) or the relevant transaction in SAP.
  Look for the annotations related to projections. Ensure that the annotation is correctly defined.
  
  
  
  Correct the Annotation Value:
  
  If the annotation is incorrectly set, change it to either #PROJECTION_LIST (if you want to specify a list of fields to be projected) or #NONE (if you do not want to project any fields).
  Example of correct annotation usage:
  @AbapCatalog.sqlViewName: 'Z_MY_CDS_VIEW'
  @AccessControl.authorizationCheck: #CHECK
  @EndUserText.label: 'My CDS View'
  @Projection: #PROJECTION_LIST
  define view Z_MY_CDS_VIEW as select from my_table
  {
      key field1,
      field2,
      field3
  }
  
  
  
  
  Activate the CDS View:
  
  After making the necessary changes, activate the CDS view to ensure that the changes take effect.
  
  
  
  Test the CDS View:
  
  Execute the CDS view to verify that the error has been resolved and that the view behaves as expected.
