  The SAP error message /UI2/GLOBAL_CACHES018 indicates that the navigation tree cache for the SAP NetWeaver Business Client (NWBC) has been invalidated for all users in the current client. This typically occurs when there are changes made to the navigation tree configuration or related objects that require the cache to be refreshed.
  Cause:
  
  Configuration Changes: Changes in the navigation tree configuration, such as modifications to roles, authorizations, or the structure of the navigation tree.

  Solution:
  
  Refresh the Cache: Users can refresh their NWBC session to rebuild the navigation tree cache. This can often be done by logging out and logging back in.
  Check Configuration: Ensure that any recent changes to the navigation tree or related configurations are correct and do not have errors.
