• What is the cause and solution for SAP error message CFD_GENERATION020 - No text association for field &1 as CDS view &2 is used in RDS service ?

  The SAP error message CFD_GENERATION020 indicates that there is a missing text association for a specific field in a Core Data Services (CDS) view that is being used in a Rapid Data Services (RDS) service. This typically occurs when the CDS view is expected to provide a text representation for a field, but the necessary text association has not been defined.
  Cause:
  
  Missing Text Association: The field in question does not have a corresponding text association defined in the CDS view. This means that the system cannot find the necessary information to display a user-friendly text for that field.
  Incorrect Field Mapping: The field might be incorrectly mapped or not included in the CDS view.
  Changes in Data Model: If there have been recent changes to the data model or the CDS view, it might have led to the removal or alteration of the text association.
  
  Solution:
  
  
  Define Text Association: 
  
  Open the CDS view in the ABAP Development Tools (ADT) or the relevant development environment.
  Ensure that the field has a proper text association defined. This can be done using the @ObjectModel.text.association annotation in the CDS view definition.
  Example:
  define view Z_MY_CDS_VIEW
  as select from my_table
  {
    key field1,
    field2,
    @ObjectModel.text.association: '_TextField'
    field3
  }
  
  Make sure that the text association points to a valid text table or a field that contains the descriptive text.
  
  
  
  Check Field Mapping: 
  
  Verify that the field is correctly mapped in the CDS view and that it is included in the select statement.
  
  
  
  Activate the CDS View: 
  
  After making changes, activate the CDS view to ensure that the changes take effect.
  
  
  
  Test the RDS Service: 
  
  After making the necessary changes, test the RDS service again to see if the error persists.
