Purchase Order Number.
This field in the Suggested Order Report window is the number that identifies this PO. You can let the system assign a PO number. It assigns PO numbers automatically if the Assign PO Numbers Automatically field in Options Configuration (or Function MPC) is Y.
Or, you can enter your own PO number, even if Options Configuration is set to Y.
The number of characters you can enter in this field depends on how option 8857 "Allow up to a 10 character vendor PO#?" is set in Options Configuration. If set to Yes, you can enter up to ten letters and numbers. If set to No, you can enter up to five letters and numbers.
