  The SAP error message "CRM_PML_UIU021 Non-secure content was filtered. Click here to display full content" typically occurs in the context of web applications, particularly when using SAP CRM (Customer Relationship Management) systems that are accessed via a web browser. This error is related to the browser's security settings, which block mixed content (i.e., a combination of secure HTTPS and non-secure HTTP content).
  Cause:
  
  Mixed Content: The error arises when a secure page (loaded over HTTPS) tries to load resources (like images, scripts, or stylesheets) over an insecure connection (HTTP). Modern browsers block this non-secure content to protect users from potential security risks.
  Browser Settings: Some browsers have strict security settings that automatically filter out non-secure content.
  Configuration Issues: The SAP system or the web application may be configured to reference non-secure resources.
  
  Solution:
  
  Use HTTPS for All Resources: Ensure that all resources (images, scripts, stylesheets) are loaded over HTTPS. This may involve updating the URLs in the SAP application or configuration settings to use HTTPS instead of HTTP.
  Browser Settings: 
  
  In some browsers, you can allow mixed content temporarily for testing purposes. However, this is not recommended for production environments due to security risks.
  For example, in Chrome, you can click on the padlock icon in the address bar, go to "Site settings," and change the "Insecure content" setting to "Allow."
  
  
  Check SAP Configuration: Review the SAP system configuration to ensure that it is set up to use secure connections. This may involve checking the web dispatcher or any reverse proxy settings.
  Update Links: If you have control over the content being served, update any hardcoded links to use HTTPS.
  Consult Documentation: Refer to SAP documentation or support for specific guidance on configuring your SAP CRM system to avoid mixed content issues.
  
  Related Information:
  
  Browser Compatibility: Different browsers may handle mixed content differently. Always test your application in multiple browsers to ensure compatibility.
  Security Best Practices: Always prioritize using HTTPS for all web applications to protect user data and maintain security standards.
  SAP Notes: Check for any relevant SAP Notes or updates that may address this issue or provide additional configuration guidance.
  
  By addressing the mixed content issue and ensuring that all resources are served securely, you should be able to resolve the error message and improve the overall security of your SAP CRM application.
