• Message number: 323

• Message text: CDS view & cannot be renamed as &; DDL source & already shipped

What causes this issue?

The DDL source has already been shipped. Since enhancements to this
source can exist in external systems or can point to the view entity
generated from it and thus presuppose its existence, renaming is not
allowed.

System Response

The object is inconsistent and activation is refused.

How to fix this error?

Undo the renaming process. If necessary, you should create a new DDL
source with the name you want. Enhancements in subsequent systems, of
course, do not point to this new object.

• What is the cause and solution for SAP error message DDLS323 - CDS view & cannot be renamed as &; DDL source & already shipped ?

  The SAP error message DDLS323 indicates that there is an issue with a Core Data Services (CDS) view that you are trying to rename. The error message states that the CDS view cannot be renamed because the Data Definition Language (DDL) source has already been shipped. This typically means that the CDS view is part of a transport request that has already been released and moved to a different system (e.g., from development to quality assurance or production).
  Cause:
  
  Transported Object: The CDS view you are trying to rename has been transported to another system, and therefore, it is locked for changes in the current system.
  Dependencies: The CDS view may have dependencies or references in other objects, which can prevent renaming.
  System Status: The system may be in a state where changes to certain objects are restricted due to transport management settings.
  
  Solution:
  
  
  Check Transport Status: Verify if the CDS view is part of a transport request that has been released. If it has, you will need to either wait for the transport to be imported into the target system or make the necessary changes in the original development system.
  
  
  Unrelease the Transport: If you have the necessary authorizations, you can try to unrelease the transport request. However, this is generally not recommended as it can lead to inconsistencies.
  
  
  Create a New Version: Instead of renaming the existing CDS view, consider creating a new version of the view with the desired name. You can then update any dependent objects to reference the new view.
  
  
  Check Dependencies: Review any dependencies or references to the CDS view. If other objects depend on it, you may need to address those dependencies before renaming.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to CDS views and transport management for any specific guidelines or best practices.
  
  
  Contact SAP Support: If the issue persists and you cannot resolve it, consider reaching out to SAP support for assistance.
