Check Parameters (OOM)

Check parameters are sets of conditions which data must satisfy to remain valid. They are attached to attributes and domains. They are principally used in a CDM or a PDM. They are of importance only when importing a CDM or importing a PDM into an OOM. They are not used in the OOM alone.

There are three types of check parameters you can therefore use in an OOM:

Parameter type	Description
Standard parameters	Common data constraints defining a data range
Additional check parameters	SQL expression defining a data constraint using variables instantiated with standard parameter values
Validation rule	Business rule defined as a server expression

Setting Standard Check Parameters for Objects in an OOM
Standard parameters indicate common data constraints.
Defining Additional Check Parameters for Objects in an OOM
You can use the following variables as check parameters for domains and attributes:
