- Classic USAS:
- User works within the current processing month
- Cannot process checks or receipts for the next month until current month is closed
- Amounts stored in "Accumulator" fields
- Month-to-Date
- Fiscal-to-Date
- Calendar-to-Date
- Accumulators cleared by ADJUST process monthly, and at end of fiscal and calendar years
- Future Purchase Orders allowed via special "future" processing
- Don't actually get posted as a purchase order until the future month becomes the current month
- It is a standard practice for ITC's to create a copy of USAS data files prior to closing with ADJUST. If audit adjustments are needed for the prior year, they may be made in the copy of the files and reports re-generated.
- USAS-R
