Source constraints

Overview

Source constraints define validation or exclusion rules for rows that come from a selected source. Use them when source data needs a documented condition before it is imported or used by downstream objects.

Function

The Source constraints dialog shows the constraints for one source in an editable grid. Each row can be tied to a source column, marked so matching rows are not imported, and given a rule statement, message statement, and business description.

When a new row is added, AnalyticsCreator associates it with the selected source. Choose Save to store the grid changes and refresh the list. Choose Cancel to close the dialog without saving pending edits.

Access

Open Source constraints from the source navigation tree commands or from the Constraints button on the Source page. A source must already be saved before constraints can be edited.

How to access

Sources -> source -> Constraints -> List source constraints or Add source constraint. Existing constraint -> Edit source constraint.
