• What is the cause and solution for SAP error message AC121 - Transport entries only possible when your changes are saved ?

  The SAP error message AC121 ("Transport entries only possible when your changes are saved") typically occurs when you attempt to transport changes in the SAP system without having saved those changes first. This error is related to the transport management system (TMS) in SAP, which is used to move development objects between different environments (like Development, Quality Assurance, and Production).
  Cause:
  
  Unsaved Changes: You have made changes to an object (like a configuration or a program) but have not saved those changes in the system.
  Transport Request: You are trying to add these unsaved changes to a transport request, which is not allowed until the changes are saved.
  
  Solution:
  
  
  Save Your Changes: Before attempting to create or add to a transport request, ensure that you have saved all your changes. You can do this by:
  
  Clicking the "Save" button in the SAP GUI.
  Using the keyboard shortcut (usually Ctrl + S) to save your changes.
  
  
  
  Check for Unsaved Changes: If you are unsure whether you have saved your changes, you can check the status of the object you are working on. If it indicates that there are unsaved changes, make sure to save them.
  
  
  Create a Transport Request: Once your changes are saved, you can proceed to create or add to a transport request without encountering the AC121 error.
  
  
  Related Information:
  
  Transport Management System (TMS): Understand how TMS works in SAP, including how to create transport requests and manage them.
  Development and Transport Process: Familiarize yourself with the development process in SAP, including the importance of saving changes and the role of transport requests in moving changes between environments.
  SAP Notes and Documentation: If you encounter persistent issues, check SAP Notes or the official SAP documentation for any updates or specific guidance related to your version of SAP.
  
  By ensuring that all changes are saved before attempting to transport them, you can avoid the AC121 error and streamline your development and transport processes in SAP.
