• What is the cause and solution for SAP error message RS2HANA_AUTH305 - Cache of class &1 cleared ?

  The SAP error message RS2HANA_AUTH305 indicates that the cache of a specific class has been cleared. This message is typically related to the authorization cache in SAP BW (Business Warehouse) when working with SAP HANA as the database. The cache is used to improve performance by storing authorization checks, and clearing it can be necessary for various reasons, such as changes in authorization roles or user assignments.
  Cause:
  
  Changes in Authorizations: The cache may be cleared when there are changes made to user roles or authorizations in the system.
  System Maintenance: Regular maintenance activities or updates may trigger the clearing of the cache.
  Performance Optimization: Sometimes, clearing the cache is done to ensure that the latest authorization settings are applied and to avoid stale data.
  
  Solution:
  
  Recheck Authorizations: After the cache is cleared, ensure that the relevant users have the correct authorizations assigned. You can do this by checking the roles and profiles assigned to the users.
  Monitor System Performance: After clearing the cache, monitor the system performance to ensure that it is functioning as expected. If performance issues arise, further investigation may be needed.
  Rebuild Cache: The cache will automatically rebuild as users access the system and their authorizations are checked again. There is typically no manual intervention required to rebuild the cache.
  Consult Documentation: If the message appears frequently or causes issues, consult SAP documentation or support for further guidance on managing authorization caches.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SU01 (User Maintenance) to check user authorizations and roles.
  Authorization Objects: Familiarize yourself with relevant authorization objects that may be affected by the cache clearing.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to authorization caching in your version of SAP BW or HANA.
  Performance Tuning: Consider performance tuning strategies if you notice significant slowdowns after cache clearing.
