• What is the cause and solution for SAP error message CFD_GENERATION036 - Denormalized Text Fields for &1 forbidden as union suffix not initial ?

  The SAP error message CFD_GENERATION036 indicates that there is an issue with the use of denormalized text fields in a union operation within a Core Data Services (CDS) view. Specifically, the error states that denormalized text fields for a certain entity (represented by &1) are forbidden when the union suffix is not initial.
  Cause:
  This error typically arises when you are trying to create a union of two or more CDS views that include denormalized text fields (e.g., fields that are not in a normalized format) and the union suffix is not set to its initial value. Denormalized text fields are often used for performance reasons, but they have specific restrictions when it comes to unions in CDS views.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Union Suffix: Ensure that the union suffix is set to its initial value. If you are using a union operation, the suffix should be empty or not specified.
  
  
  Review Denormalized Fields: If you need to include denormalized text fields in your union, consider whether you can refactor your CDS views to avoid using these fields in the union. You may need to create separate views or modify the existing ones to comply with the restrictions.
  
  
  Modify the CDS View: If the denormalized text fields are not essential for the union operation, you can remove them from the CDS view definition that is causing the error.
  
  
  Consult Documentation: Review the SAP documentation for Core Data Services and the specific restrictions related to denormalized text fields and unions. This can provide additional context and guidelines for structuring your views.
  
  
  Testing: After making the necessary changes, test the CDS view to ensure that the error is resolved and that the view behaves as expected.
