Sometimes, a Data Load on a target, usually a Datamart, is scheduled to run very frequently.
Also, several Data Loads with the same target could run in sequence (refresh, enrichment, etc.). In these cases it would be useful to disable the automatic Index Maintenance job scheduling and schedule it manually at the end of the sequence.
