There are three ways to work with Purchase Order numbers.
Use Max Calculation - Masterpiece will look at the existing PO numbers in your system to find the highest current number and will then add 1 to that number.
Use NextID Table - This option should be used if you are working on a Network. Each time you start a Purchase Order, Masterpiece uses a table (storage area) to record the number used. When working on a network, two or more workstations may be doing POs at the same time. Thus, it is important that two operators do not use the same number.
Note that if you start a purchase order and then cancel it, the number is still "USED UP" so there can be skips in the numbering.
When this option is selected you can also use the EDIT PO NUMBER check box. See Below.
No Calculation - This option tells Masterpiece not to bother looking for the next number because you will enter it manually for each Purchase Order. This is useful if you ALWAYS work off of preprinted manual invoices and the system is being used only as a "back office" station.
As mentioned above, when you use the NextID table to allocate purchase order numbers, some numbers may not be used because of cancelled records. If this box is selected, the operator has the option of manually entering the unused numbers to "use them up."
