The Domain object has a key position. It describes the value range for table columns. Domains permit data elements to be defined centrally and used in any tables, programs, and forms. Thus, you can introduce a list of data elements for an area of application.
Relationships between a domain and other objects:
1. Column Refers to Domain
2. Module Uses Domain
3. User Owns Domain
1. A column can be defined by a DOMAIN; a DOMAIN can be used for a number of column definitions (N[0]-1).
2. A module can be used for a number of DOMAIN definitions; a DOMAIN definition can be used in a number of modules (N[0]-M[0]).
3. A user can own several DOMAIN definitions; a DOMAIN definition is owned by exactly one user (1-M[0]).
