This feature allows for faster access to data, as the data is stored in memory and can be accessed quickly. The dynamic cache also helps to reduce the amount of database requests, which can help to improve system performance. 
  
  How to use it: 
  In order to use the dynamic cache, you must first activate it in the ABAP Dictionary. This can be done by selecting the “Activate Dynamic Cache” option in the ABAP Dictionary. Once activated, the dynamic cache will automatically cache data from database tables when they are accessed. 
  
  Tips & Tricks: 
  When using the dynamic cache, it is important to ensure that the data being cached is up-to-date. To do this, you can set a refresh interval for the dynamic cache, which will ensure that any changes made to the database tables are reflected in the cached data. Additionally, you can also manually refresh the dynamic cache if needed.
