Static and Dynamic Selections

A selection can be either static or dynamic. A static selection is a fixed set of IDs that does not change. For example, if a record that originally met the criteria of the query on which the selection is based changes so that it does not currently meet the criteria, the record ID is still included in the selection each time it is processed. A dynamic selection analyzes membership each time it is used in a function, so records may be added or removed from it each time it runs.
