• What is the cause and solution for SAP error message WXP175 - Data was changed. Save before exiting ?

  SAP Error Message:
  
  WXP175 - Data was changed. Save before exiting
  
  Cause:
  This message appears in SAP Web Dynpro applications when the user attempts to navigate away from a screen or exit a transaction without saving the changes made to the data. The system detects that the data in the current context has been modified but not yet saved, and it prompts the user to save these changes before leaving to prevent data loss.
  
  Explanation:
  
  In Web Dynpro applications, the data context is bound to UI elements.
  When a user modifies data (e.g., input fields), the context node is marked as changed.
  If the user tries to exit or navigate away without saving, the framework triggers this warning.
  This is a safeguard to ensure that unsaved changes are not lost unintentionally.
  
  
  Solution:
  
  
  Save the Data:
  
  Before exiting or navigating away, save the changes by clicking the Save button or triggering the save action.
  This commits the changes to the database or backend system.
  
  
  
  Discard Changes:
  
  If you do not want to keep the changes, explicitly discard or reset the data before exiting.
  Some applications provide a Cancel or Reset button to revert changes.
  
  
  
  Check Application Logic:
  
  If this message appears unexpectedly, verify that the application properly handles save and exit logic.
  Developers can implement confirmation dialogs or automatic save prompts.
  
  
  
  User Training:
  
  Inform users about the importance of saving data before exiting.
  Encourage them to use the save functionality regularly.
