Hi Sunny....
The purpose of the site user is to provide an additional level of security for access to SAP Business One data when important administrative actions are performed. While the actions of an SAP Business One regular user or superuser apply at company or database level, the actions of the site user are valid at the customer site level, where one site can comprise a license server as well as multiple other servers.
The site user ID serves as site-level authentication for performing the following activities:
Configuring database credentials
Creating companies
Configuring services: for example, registering database servers and configuring their access credentials in the License Manager security settings
Registering add-ons
Upgrading companies
Updating read-only user passwords
A site user password is required for authentication against the license server during the following situations:
Configuring services using SAP Business One Service Manager
These services are SBO Backup, SBO DI Server, License Manager, and SBO Mailer.
Installing SAP Business One servers
Creating new companies on SAP Business One clients
In the License server you provide your license sever ip....
Hope helpful
