Set up dynamic queries

Use a dynamic query to find one or more records in the database. The found records are the input for further processing.

You can use a dynamic query on:

  • An enrichment rule of type Data query.
  • An action rule of type Data query.
  • A condition that is applied to a validation rule, duplicate check rule, or action rule.
  • A configurable lookup of type Dynamic query. You can apply the configurable lookup on a validation rule of type Configurable lookup.

To define a query range, you can use a function.
