Smart SAP Assistant

• What is the cause and solution for SAP error message SADL_GW_DT_CDS029 - CDS view &1 cannot be draft-enabled due to underlying transactional view. ?

  The SAP error message SADL_GW_DT_CDS029 indicates that a Core Data Services (CDS) view cannot be draft-enabled because it is based on an underlying transactional view that does not support draft functionality. This typically occurs in the context of SAP Fiori applications that utilize draft handling for data persistence.
  Cause:
  The error arises when you attempt to enable draft functionality for a CDS view that is based on a transactional view (or a view that does not support draft capabilities). Draft handling in SAP is designed to work with specific types of data models, and if the underlying data source does not support this feature, the draft functionality cannot be enabled.
  Solution:
  To resolve this issue, consider the following steps:
  
  
  Check the Underlying View: Review the underlying transactional view that your CDS view is based on. Ensure that it is designed to support draft functionality. If it is not, you may need to create a new view or modify the existing one.
  
  
  Create a New CDS View: If the underlying transactional view cannot be modified to support drafts, consider creating a new CDS view that is based on a different data source that does support draft functionality.
  
  
  Use a Different Approach: If draft functionality is not essential for your application, you may choose to proceed without enabling drafts. This would involve removing any draft-related annotations from your CDS view.
  
  
  Consult Documentation: Refer to the SAP documentation for guidelines on enabling draft functionality in CDS views. This can provide insights into the requirements and limitations of draft-enabled views.
  
  
  Check for Updates: Ensure that your SAP system is up to date, as newer versions may have improved support for draft handling or additional features that could help resolve the issue.
  
  
  Related Information:
  
  Draft Handling in SAP: Understand the concept of draft handling in SAP Fiori applications and how it is implemented in CDS views.
  CDS Annotations: Familiarize yourself with the annotations used in CDS views, particularly those related to draft handling, such as @ObjectModel.draftEnabled.
  SAP Community and Support: Engage with the SAP Community or SAP Support for additional insights and potential solutions from other users who may have encountered similar issues.
  
  By following these steps, you should be able to address the error and either enable draft functionality or adjust your approach accordingly.
