How to change the default SAP GUI client number

How do you change the default SAP GUI client number when you initially click on the environment to log in? One of the experts said you need to change an instance profile parameter on the R/3 system. The parameter is:

login/system_client
The default value is 000.

You need to make the change, save the instance profile and activate it. Then, stop and start the R/3 instance for the change to take effect. How and where can I do that?

Hi,

The expert gave you the right solution. In order to change the instance profile parameter, use the TCODE RZ10 and select the instance profile for which you want to perform the changes. Now open the instance profile in change mode and add the parameter login/system_client with the required client number. Save your change and activate. Now, stop and start the R/3 instance for the change to take effect.
