• What is the cause and solution for SAP error message SD_CDS_PROJECTION009 - Definition of a Where-Condition is not supported in Projection View ?

  The SAP error message SD_CDS_PROJECTION009 indicates that there is an issue with the definition of a where-condition in a projection view within the Core Data Services (CDS) framework. This error typically arises when you attempt to use a where-condition in a projection view, which is not supported by the CDS framework.
  Cause:
  The primary cause of this error is that projection views in CDS are designed to define a specific structure of data without applying any filtering or conditions. When you try to include a where-condition in a projection view, the system raises this error because it violates the intended use of projection views.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Remove the Where-Condition: If the where-condition is not essential for the projection view, you can simply remove it. This will allow the projection view to function correctly without any filtering.
  
  
  Use a Different Type of View: If you need to apply filtering, consider using a different type of CDS view, such as a Basic View or a Composite View. These types of views allow for more complex logic, including where-conditions.
  
  
  Refactor the View: If you need to keep the projection view but also require filtering, you can create a separate view that includes the necessary where-conditions and then join or use that view in your projection view.
  
  
  Check Documentation: Review the SAP documentation for Core Data Services to understand the limitations and best practices for creating projection views. This can help you design your views correctly from the start.
