• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK453 - Union suffix &1: CDS View &2 has different Text Handling than CDS View &3 ?

  The SAP error message CFD_REGISTRY_CHECK453 indicates a mismatch in text handling between two Core Data Services (CDS) views. This error typically arises when you are trying to create a union of two CDS views that have different text handling configurations. 
  Cause:
  The error occurs because the two CDS views involved in the union have different definitions for how they handle text fields. Specifically, the text handling can differ in terms of:
  
  Language-dependent vs. language-independent text handling.
  Different text field types or structures.
  
  When you attempt to create a union of these views, SAP checks the compatibility of the text handling. If they do not match, the system raises this error.
  Solution:
  To resolve this error, you need to ensure that both CDS views have consistent text handling. Here are the steps you can take:
  
  
  Review the CDS Views: Check the definitions of both CDS views (&2 and &3) to identify how text fields are defined. Look for any discrepancies in the text handling.
  
  
  Align Text Handling:
  
  If one view uses language-dependent text fields (e.g., TEXT or TEXT_L), ensure that the other view uses the same type.
  If one view uses a specific text structure, modify the other view to match that structure.
  
  
  
  Modify the CDS Views: If necessary, update the CDS views to ensure they have the same text handling. This may involve changing the annotations or the way text fields are defined.
  
  
  Test the Union: After making the necessary changes, test the union again to see if the error persists.
  
  
  Documentation: Document the changes made for future reference and to maintain consistency in your CDS views.
  
  
  Related Information:
  
  CDS Views: Core Data Services (CDS) are a way to define semantically rich data models in SAP. They allow for the definition of views that can include complex logic, associations, and annotations.
  Text Handling in CDS: Text handling in CDS views can be defined using annotations such as @ObjectModel.text or @ObjectModel.text.element. Understanding these annotations is crucial for ensuring compatibility.
  SAP Notes and Documentation: Check SAP Notes or the official SAP documentation for any updates or additional guidance related to CDS views and text handling.
  
  By ensuring that the text handling is consistent across the CDS views involved in the union, you should be able to resolve the CFD_REGISTRY_CHECK453 error.
