Setting Up a Default Task Status
Before a Call Status can be changed to COMPLETE, the status of all tasks attached to an appointment must be marked as COMPLETE, SKIPPED, or N/A. Use the Service Call Tasks window to update the task statuses. If any task status remains set to OPEN, a warning message will appear when you attempt to complete the call.
In addition, a default Task Status must be selected in Service Options, to create MCC calls.
Select Microsoft Dynamics GP > Tools > Service Management > Module Setup > Service Options. Select a default Task Status. This status will be automatically selected for tasks when they are added to appointments.
