• Key Concepts: 
  Maintenance mode is a feature of the BC-CST-IC Internet Communication Manager (ICM) component of SAP. It allows administrators to temporarily disable certain services or functions of the ICM, such as HTTP, HTTPS, and FTP, while still allowing other services to remain active. This allows administrators to perform maintenance tasks without disrupting the normal operation of the system. 
  
  How to use it: 
  To enable maintenance mode, administrators must first log into the SAP system and navigate to the ICM configuration page. From there, they can select the “Maintenance Mode” option and enter a description of the maintenance task they are performing. Once enabled, all services or functions that have been disabled will remain disabled until maintenance mode is disabled. 
  
  Tips & Tricks: 
  When enabling maintenance mode, it is important to remember to disable it once the maintenance task has been completed. This will ensure that all services and functions are restored to their normal state. Additionally, it is important to remember that any changes made while in maintenance mode will not be saved until maintenance mode is disabled.
