Consider the following scenario in Microsoft Dynamics SL:
- In Service Dispatch in Service Call Entry (SD.200), enter in a new Service Call for any customer and Save.
- Open the Invoice button at the bottom and enter any required fields in Invoice Entry (SD.202) screen and Save.
- Open Invoice T&M Details (SD.203) and enter a Billable line for an Inventory Item (item would be non-stock and user specified cost).
- Enter a Quantity and Unit Cost and tab through the Service Date. You will notice the Unit Cost is reset to zero.
