• What is the cause and solution for SAP error message /UI5/APP_API155 - No. of changes skipped &1 (content unchanged) ?

  The SAP error message /UI5/APP_API155 No. of changes skipped &1 (content unchanged) typically occurs in the context of SAP Fiori applications and the UI5 framework. This message indicates that a certain number of changes or updates to the application were not applied because the content being modified has not changed. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  No Changes Detected: The error message suggests that the application attempted to apply changes to the UI5 model or data binding, but the data being updated is identical to the existing data. As a result, the framework skips these changes to optimize performance.
  Data Binding Issues: If the data binding is not set up correctly, or if the model is not updated properly, it may lead to this message.
  Caching: Sometimes, caching mechanisms may prevent the application from recognizing changes, leading to this message.
  
  Solution:
  
  Check Data Changes: Ensure that the data you are trying to update has actually changed. You can log the data before and after the update to verify this.
  Force Update: If you are certain that the data has changed but the application is not recognizing it, you can force an update on the model. For example, you can call refresh() on the model to reload the data.
  yourModel.refresh(true);
  
  Review Data Binding: Ensure that the data binding in your UI5 application is correctly set up. Check if the model is properly bound to the controls and that the data is being updated in the model.
  Debugging: Use debugging tools to step through the code and identify where the changes are being skipped. This can help you understand the flow of data and where the issue might be occurring.
  Clear Cache: If caching is suspected to be the issue, try clearing the browser cache or any application-level cache that might be holding onto old data.
  
  Related Information:
  
  SAP UI5 Documentation: Refer to the official SAP UI5 documentation for more details on data binding and model updates.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.
  Performance Optimization: Understand that skipping unchanged updates is a performance optimization feature in UI5, and it is generally beneficial for application performance.
  
  By following these steps, you should be able to address the error message and ensure that your SAP Fiori application functions as intended.
