Tables contain a set of entries against which data can be validated.
A table comprises a table definition and a number of table entries that represent the valid values. CAS provides a facility for creating and maintaining table definitions and entries.
Each table entry can have an abbreviated value, description, and up to ten associated data fields.
Valid values in a table can be specified explicitly as table entries or can be drawn from the following sources:
You can define an exit procedure for a table that performs installation specific processing during table entry maintenance—for example, to validate table entries or restrict the deletion of entries.
