• What is the cause and solution for SAP error message HTTP_CHW_UI_MSG013 - Set Whitelist active ?

  The SAP error message HTTP_CHW_UI_MSG013, which states "Set Whitelist active," typically relates to the configuration of the HTTP Content Security Policy (CSP) in the SAP system. This error often occurs when the system is trying to enforce security policies that restrict the loading of resources from certain domains, and the required whitelist settings are not properly configured.
  Cause:
  
  CSP Configuration: The error indicates that the Content Security Policy (CSP) is not set up correctly, and the necessary domains are not included in the whitelist.
  Missing Whitelist Entries: The application may be trying to load resources (like scripts, styles, or images) from domains that are not included in the whitelist.
  Security Settings: The security settings in the SAP system may be too restrictive, preventing the application from functioning correctly.
  
  Solution:
  To resolve the HTTP_CHW_UI_MSG013 error, you can follow these steps:
  
  
  Access the SAP System: Log in to your SAP system with the necessary administrative privileges.
  
  
  Navigate to the CSP Configuration:

  Find the relevant service for your application (e.g., /sap/bc/ui5_ui5).
  
  
  
  Edit the Service:

  Look for the "CSP" settings or "Whitelist" settings.
  
  
  
  Add Required Domains:

  Ensure that you include both the protocol (http/https) and the domain name.
  
  
  
  Activate the Whitelist:
  
  Ensure that the whitelist is activated. There should be an option to set the whitelist as active.
