  The SAP error message XM021 ("Tool already logged on") typically occurs when a user attempts to log into a tool or application that is already logged in with the same user credentials. This can happen in various SAP environments, including SAP GUI, SAP BusinessObjects, or other SAP-related tools.
  Causes:
  
  Multiple Sessions: The user may have multiple sessions open with the same credentials, leading to a conflict.
