• What is the cause and solution for SAP error message W3_API004 - MiniApps are no longer supported ?

  SAP Error Message:
  
  W3_API004 MiniApps are no longer supported
  
  Cause:
  This error occurs because MiniApps, a legacy technology used in older SAP web applications, have been deprecated and are no longer supported in the current SAP NetWeaver or SAP UI frameworks. SAP has phased out MiniApps in favor of newer, more robust technologies such as SAPUI5/Fiori apps.
  When an application or a component tries to invoke or load a MiniApp, the system throws this error indicating that the requested MiniApp cannot be processed.
  
  Explanation / Background:
  
  MiniApps were small, lightweight web applications used in older SAP Web Dynpro or BSP (Business Server Pages) environments.
  SAP has moved towards modern UI technologies like SAPUI5 and Fiori, which provide better user experience, responsiveness, and integration capabilities.
  As part of this transition, support for MiniApps has been discontinued in newer SAP NetWeaver releases and SAP Gateway services.
  
  
  Solution:
  
  
  Migrate MiniApps to SAPUI5/Fiori Apps:
  
  Identify the MiniApps currently in use.
  Redesign and redevelop these applications using SAPUI5 or Fiori frameworks.
  SAP provides tools and guidelines for migrating legacy UI technologies to SAPUI5.
  
  
  
  Check for Configuration or Custom Code:
  
  Review any custom developments or configurations that might still be referencing MiniApps.
  Remove or update these references to point to supported UI technologies.
  
  
  
  Update SAP Components:
  
  Ensure that your SAP system and UI components are updated to the latest support packages.
  Verify that no legacy MiniApp components are deployed.
  
  
  
  Consult SAP Notes and Documentation:
  
  Look for SAP Notes related to MiniApps deprecation.
  SAP may provide migration guides or patches to assist in the transition.
