When finishing a purchase order and an item(s) order quantity exceeds a 12 month supply (adjusted by backorder quantity, open order quantity, allocated quantity, on hand quantity, quarantine quantity, and missing on hand quantity) of an item(s), CODIS will alert the user. The intention of the alert is to help prevent accidentally ordering an erroneous quantity that would result in an overstock situation. The following screen shot displays items on the purchase order whereas the quantity ordered exceeds the previous 12 months movement. The setup date of the stock file record is also displayed. Enter “Y” to accept the purchase order ‘as is’. Enter “N” to return to the purchase order if you need to change the order quantities. Enter “A” to change the warehouse code(s) used in the ‘sanity check’ calculation (useful in combining warehouse movement).
