A base report is a report that was designed by Dynafact and came with DMS.  These reports are used as they are; they cannot be customized nor can they be deleted unless the report's status as a base report is changed.  In order to customize a base report, it is recommended that you make a copy of a base report, and then customize the copied report. Using this method, you can use the base reports as templates for creating new customized reports.
