The logging behavior determines when recorded information is entered into a specific bucket.
Different behaviors could be created for different types of buckets or the same bucket, however - only one behavior can be applied to a bucket.
For example:
Overtime opportunity hours record to the Overtime bucket.
Special event overtime opportunities that are greater than 4 hours in duration, record to the Special Event bucket.
All special event opportunity hours also record to the Overtime bucket.
In the example above, there are two buckets with two distinct behaviors. The Overtime bucket logs all hours associated with an overtime opportunity which includes special event opportunities regardless of the duration whereas the Special Event bucket logs only special event opportunities greater than four hours.
Buckets must be recalculated when field parameters in either a bucket or behavior change.
