The End-of-Period Submenu contains programs that should be run to close the module correctly at the end of each period. The Item Activity Report provides a printout of all item activity (receipts, adjustments, sales, transfers, etc.) for the period. This information is reset after the period is closed, so it must be printed at this time. The Serial/lot Number Removal Register prints a list of all serial/lot numbers that have been sold and optionally removes them from the system. The System Clean Up F/M (SMF993) removes ledgercards for all items before a specified date - failure to run this program may result in an overly large ledgercard file. The End-of-Period Update closes the current IC period, rolls usage figures back one period, recalculates ordering controls, and resets month-to-date sales figure for all items. Items with unusual usage for the period are flagged.
