Usage Codes define the conditions a resource was used under. For example, if a person works a standard eight-hour day, their Usage Code is 'Normal'.  Usage Codes can be added for People, Equipment and Other Resources. Usage Codes are different from Rate Codes (the amount of money a resource costs for a certain quantity) and Work Roster Codes (the dates a person starts and ends working).
