• What is the cause and solution for SAP error message WD094 - After deleting reusable units, please use new version. ?

  SAP Error Message:
  
  WD094 – "After deleting reusable units, please use new version."
  
  Cause:
  This error occurs in the Web Dynpro ABAP environment when you delete reusable units (such as components, component controllers, or other reusable Web Dynpro artifacts) that are part of a Web Dynpro application or component, but the system detects that the application/component is still referencing the old version of these units.
  In other words, after deleting reusable units, the Web Dynpro application/component metadata or usage references are out of sync because the system expects you to create or use a new version of the application/component that reflects these changes.
  
  Explanation:
  
  Reusable units in Web Dynpro are components or controllers that can be reused across different applications or components.
  When you delete such units, the existing application/component that used them still references the old versions.
  SAP requires you to create a new version of the application/component to ensure consistency and to avoid runtime errors.
  This mechanism prevents inconsistencies and ensures that the Web Dynpro runtime environment uses the correct and updated versions of all reusable units.
  
  
  Solution:
  
  
  Create a new version of the Web Dynpro component or application:
  
  Go to the Web Dynpro component or application in the SAP development environment (SE80 or Web Dynpro Explorer).
  Use the "Create New Version" function to generate a new version of the component/application.
  This new version will no longer reference the deleted reusable units and will be consistent with the current state of your development objects.
  
  
  
  Adjust references if necessary:
  
  After creating the new version, check all references and usages of reusable units.
  Make sure that any usage of reusable units points to existing and valid units.
  
  
  
  Activate the new version:
  
  Activate the new version of the component/application.
  Test the application to ensure that it works correctly without referencing deleted units.
  
  
  
  Transport the new version:
  
  If you are working in a multi-system landscape, transport the new version to the quality and production systems.
  
  
  
  
  Related Information:
  
  Transaction SE80: SAP Object Navigator, where you can manage Web Dynpro components and applications.
  Web Dynpro Explorer: Another tool to manage Web Dynpro development objects.
  SAP Note or documentation on Web Dynpro version management.
  Best practice: Always create a new version of Web Dynpro components/applications after structural changes like deleting reusable units.
  This error is a safeguard to maintain consistency in Web Dynpro applications and prevent runtime errors due to missing or deleted reusable units.
  
  
  Summary:
  
  Cause: Deletion of reusable units without creating a new version of the Web Dynpro component/application.
  Solution: Create and activate a new version of the Web Dynpro component/application to reflect the changes.
  Result: Ensures consistency and prevents runtime errors related to missing reusable units.
