• Key Concepts: 
  Extended memory is a feature of the SAP Memory Management component (BC-CST-MM) that allows for the allocation of additional memory to an application. This additional memory is used to store data that would otherwise be stored in the main memory, thus freeing up space in the main memory for other tasks. The extended memory can be used for both read and write operations, and can be accessed by multiple applications at the same time.
  
  How to use it: 
  In order to use extended memory, an application must first be configured to use it. This is done by setting the “extended_memory” parameter in the SAP Memory Management configuration file. Once this parameter is set, the application can then access the extended memory by using the appropriate API calls.
  
  Tips & Tricks: 
  When using extended memory, it is important to ensure that the amount of memory allocated is sufficient for the task at hand. If too little memory is allocated, then performance may suffer as a result. Additionally, it is important to ensure that the extended memory is properly managed and monitored, as it can become fragmented over time if not properly managed.
