 ### Error - Misconfigured SAP System
 **Cause:** This issue occurs when multiple ASCS (MESSAGESERVER and/or ENQREP) instances present in the configured SAP, which isn't a valid configuration. Ensure that there exists only one ASCS instance for the SID.

 2. Run "ps -ef | grep sapstartsrv", and take note of the command line related to the sapstartsrv process from the affected instance;
 3. Run "sapcontrol -nr <$$> -function StopService". Run the "ps" command again (see the previous step), and ensure that the sapstartsrv process was stopped (<$$> is the number of the affected instance);
 4. Access the folder "/usr/sap/'SID'/SYS/global/sapcontrol".
