• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK055 - Include View &1 does not contain alias 'Persistence' ?

  The SAP error message CFD_REGISTRY_CHECK055, which states "Include View &1 does not contain alias 'Persistence'," typically occurs in the context of SAP's Core Data Services (CDS) views or when working with the ABAP programming model for SAP Fiori applications. This error indicates that the specified include view does not have the required alias for persistence, which is necessary for the system to recognize it as a valid data source.
  Cause:
  
  Missing Alias: The include view specified in the error message does not define an alias named 'Persistence'. This alias is essential for the system to understand how to handle the data from the view.
  Incorrect View Definition: The view might not be defined correctly, or it may not be intended for persistence.
  Changes in the Data Model: If there have been recent changes to the data model or the underlying database tables, the include view may not have been updated accordingly.
  
  Solution:
  
  
  Check the Include View Definition:
  
  Open the include view in the ABAP Development Tools (ADT) or the relevant transaction (like SE11 or SE80).
  Ensure that the view includes the alias 'Persistence'. This can typically be done by adding the following line in the view definition:
  @AbapCatalog.sqlViewName: 'Your_SQL_View_Name'
  @AbapCatalog.compiler.compareFilter: 'Your_Comparison_Filter'
  define view Your_View_Name as select from Your_Table_Name
  {
      key field1,
      field2,
      ...
  }
  
  Make sure to include the alias in the appropriate section of the view definition.
  
  
  
  Activate the View: After making changes, ensure that you activate the view. This step is crucial for the changes to take effect.
  
  
  Check Dependencies: If the include view is used in other views or programs, ensure that all dependencies are correctly defined and activated.
  
  
  Review Documentation: If you are unsure about the correct structure of the include view, refer to SAP documentation or guidelines for creating CDS views and include views.
  
  
  Consult with Colleagues or SAP Support: If the issue persists, it may be helpful to consult with colleagues who have experience with CDS views or reach out to SAP support for further assistance.
