Creating Domains
Use Domain Maintenance (36.10.1) to define domains in the current database. You create two types of domains:
Primary domains reference the current database.
Connection domains point to domains located in other databases.
Most functions update data within a specific domain. For example, each domain has its own base currency, chart of accounts, and control settings. All business documents—such as sales orders, purchase orders, and work orders—reference a specific domain.
A few system maintenance functions update data shared by all domains. These include functions such as printers, users, menus, messages, and currency codes.
Programs Updating System-Wide Data lists these functions.
The Header Display Mode setting in Security Control (36.3.24) determines if the current domain name displays in program title bars in the character and Windows user interfaces. When the domain name displays, programs that update shared data display All Domains in the title bar. Programs that update domain-specific data display the domain short name and currency instead.
