Adding values from logs
To simplify the list creation process, you can gather values from the set of dimension values that are automatically stored in the database logs for 14 days. When a sufficient sample accrued in the log files, you may download those values, edit them, as needed, and then import back into the dimension whitelist, blacklist, or group list.
Note: After you initially create a dimension, it may take a variable length of time before the
database logs begin to be populated with a meaningful number of values. If no values for the
dimension were detected in the transaction stream or if the logs were recently purged, the list
of available values may be empty. See Recommended workflow for creating dimension populated by logged values.
