SADL_GW_DT_CDS004 - Details

• The SAP error message SADL_GW_DT_CDS004 indicates that the data source you are trying to use is not a transactional Core Data Services (CDS) view. This error typically arises when you attempt to use a CDS view that is not designed for transactional operations in a context that requires a transactional data source.
  
  Cause:
  
  Non-Transactional CDS View: The CDS view you are trying to access is not defined as a transactional view. Transactional views are designed to support operations like Create, Read, Update, and Delete (CRUD).
  Incorrect Data Source: You may be using a data source that is intended for analytical purposes or reporting, rather than for transactional processing.
  Misconfiguration: There might be a misconfiguration in the way the CDS view is set up or how it is being called in your application.
  
  
  Solution:
  
  
  Check the CDS View Definition: Verify the definition of the CDS view in the ABAP Development Tools (ADT) or in the SAP GUI.
