Track Changes to Tasks
SugarCRM provides the ability to "Audit" several built-in modules. This allows system administrators to monitor changes to key fields, e.g. name, status fields, and user assignment. Unfortunately this ability is not enabled for the Tasks module. This SugarCRM add-on fixes that by tying the Tasks module into the existing Audit system.
Audit Any Task Field
Right from within SugarCRM Studio you can select any field in the Tasks module and set it to be audited. Now whenever someone makes a change to that field you'll know who did it and when.
