• What is the cause and solution for SAP error message HTTP_CSP_UI_MSG002 - To Whitelist ?

  The SAP error message HTTP_CSP_UI_MSG002 typically indicates that a certain URL or resource is not whitelisted in the Content Security Policy (CSP) settings of your SAP system. This can prevent certain functionalities from working correctly, especially in web applications that rely on external resources.
  Cause:
  The error occurs when the application tries to access a resource (like a script, image, or stylesheet) that is not included in the CSP whitelist. CSP is a security feature that helps prevent various types of attacks, such as Cross-Site Scripting (XSS) and data injection attacks, by controlling which resources can be loaded and executed in the browser.
  Solution:
  To resolve this error, you need to update the CSP settings in your SAP system to include the necessary URLs or resources. Here are the general steps to do this:
  
  
  Identify the Resource: Determine which resource is being blocked. This information is usually provided in the error message or can be found in the browser's developer console.
  
  
  Access the CSP Configuration:
  
  Log in to your SAP system.
  Navigate to the transaction code SICF (Internet Communication Framework).
  Find the service that corresponds to your application.
  
  
  
  Modify the CSP Settings:
  
  In the service configuration, look for the "CSP" tab or section.
  Add the necessary URLs or domains to the whitelist. This may include domains for external libraries, APIs, or other resources that your application needs to access.
  
  
  
  Save and Activate: After making the changes, save the configuration and activate the service.
  
  
  Test the Application: Refresh your application in the browser to see if the error persists. If it does, double-check the URLs you added to ensure they are correct.
  
  
  Related Information:
  
  CSP Directives: Familiarize yourself with the different CSP directives (like script-src, img-src, etc.) to understand how to properly configure the whitelist.
  Browser Developer Tools: Use the developer tools in your browser (usually accessible via F12) to monitor network requests and see which resources are being blocked.
  SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional guidance on configuring CSP in your specific version of SAP.
  Security Considerations: Be cautious when whitelisting resources, as overly permissive settings can expose your application to security vulnerabilities.
