The standard range for SAP instance numbers is 00 to 97. For 98 and 99, they are saved for;
- 98: Reserved for the Diagnostics Agent.
- 99: Reserved for the SAProuter.
You can find the SAP instance number using any of these methods:
Using SAP Logon
Open SAP Logon. Right-click your system and choose Properties and look for System Number in the connection details.
Using Transaction Code
Open transaction code SM51, under the application server instance, you can see the instance number.
Go to System -> Status and you will see the instance number under the server name.
Using Operating System level
Log in to your server (like Windows). Go to the folder: usr/sap/SID and look for a folder starting with D or DVEBMGS:
- D00: The instance number is 00 (common for additional servers).
- DVEBMGS01: The instance number is 01 (common for the main central instance).
Using SAP MMC
Open SAP MMC. Look at the end of the server name; the number you see there is your instance number (for example, 0 means 00 and 1 means 01).
