Some fields are associated with Select Value lists
from which you can choose an appropriate value. The lists of defined
values are known as domains (sometimes referred to as value
lists).
You can work with the following types of domains:
- ALN
- A list of alphanumeric values.
- Crossover
- A special table domain in which the system brings back another
value (or values) from the specified record.
- Numeric
- A list of numeric values.
- Numeric range
- A list of numeric values that you define by specifying a range.
- Synonym
- These are special, reserved domains in the system. You cannot
add or delete synonym domains. You can add new synonym values that
are presented to the user.
- Table
- A list of values generated from a table.
Internal and non-internal domains
Some domains
are used by the business logic of the system. These domains are called internal domains.
If
you attempt to edit an internal domain, you encounter the following
restrictions:
- You can modify only the description of the internal domain and
internal domain values.
- You cannot add or delete a row of values from an internal domain.
- You cannot delete an internal domain.
