SAPGUI: Maximum Number of Connected Terminals Reached

Share this article :


When user tries to log on to the SAP System, an error message is issued: “Maximum number of connected terminals reached”


The maximum number of connections per instance is determined by parameter rdisp/tm_max_no (default setting: 200).  When this number is reached, no further logons are possible.


• Increase the parameter rdisp/tm_max_no.

• Restart the affected instance.

• Kick any old users from the system.


• If you do not log off properly (for example, switching off the PC without logging off), the connection is retained until it is exited because of a timeout (see note 27320).  As a result, the number of open connections may be greater than the number of users logged on to the system.

• SAP note 22099
