• What is the cause and solution for SAP error message DDUT200 - ===================== Convert Tables to CDS Views ======================= ?

  The SAP error message DDUT200, which indicates the need to "Convert Tables to CDS Views," typically arises when you are trying to use a database table in a context where a Core Data Services (CDS) view is expected. This is particularly relevant in the context of SAP S/4HANA, where the use of CDS views is encouraged for better performance, flexibility, and integration with modern SAP technologies.
  Cause:
  
  Legacy Tables: The error often occurs when legacy database tables are being used in a scenario that requires a CDS view, such as in analytical applications or Fiori apps.
  Incompatibility: Certain functionalities in SAP S/4HANA, such as OData services or analytical queries, may not support direct access to database tables and instead require CDS views.
  Development Environment: If you are working in a development environment that has been configured to use CDS views, attempting to access a standard table directly can trigger this error.
  
  Solution:
  
  Create a CDS View:
  
  Use the ABAP Development Tools (ADT) in Eclipse to create a new CDS view.
  Define the CDS view based on the existing database table. You can use the @AbapCatalog.sqlViewName annotation to specify the SQL view name and the @AbapCatalog.compiler.compareFilter annotation to manage the comparison filter.
  Example:
  @AbapCatalog.sqlViewName: 'Z_MY_CDS_VIEW'
  @AbapCatalog.compiler.compareFilter: true
  define view Z_MY_CDS_VIEW as select from my_table {
    key field1,
    field2,
    field3
  }
  
  
  
  Use the CDS View: After creating the CDS view, replace the references to the original table in your application or report with the new CDS view.
  Check for Existing CDS Views: Before creating a new CDS view, check if there are existing CDS views that already provide the required data. This can save time and effort.
  Testing: After implementing the CDS view, test it thoroughly to ensure it meets the functional requirements and performs well.
  
  Related Information:
  
  CDS Views: Core Data Services (CDS) is a framework that allows you to define semantic data models in a database-agnostic way. CDS views can be used for reporting, analytics, and application development.
  Performance: CDS views are optimized for performance in SAP HANA, leveraging the capabilities of the in-memory database.
  Annotations: CDS views support various annotations that can enhance their functionality, such as defining UI elements, authorization checks, and more.
  Documentation: Refer to the official SAP documentation on CDS views for detailed guidelines on creating and using them effectively.
  
  By following these steps, you should be able to resolve the DDUT200 error and successfully convert your tables to CDS views.
