Charge Class (CHRG) defines how charge class values are used on Job Charge (JC) documents. Charge classes are different types of goods and services whose use is added to the cost of a job. This window is shared by extended projects in the baseline system and contains the standard rate for each charge class. On non-accounting Job Charge (JC) documents, the system computes the full cost charged to a job by multiplying the number of units entered on the Job Charge (JC) document by the standard rate in this window. A standard cost per unit is established for each charge class. Examples of entries on this window are labor at $10 per hour; computer use at $.03 per printout page; and mileage at $.15 per mile.
