If the symptoms include a different item code and description are printing on the Purchase Order than is being shown what is on the screen, the culprit is most likely an item that was previously copied from another item. When this happens, the vendor code and description on the vendor tab is also copied. Many times people forget to look at this tab after the copy is done. This leaves the item with the new code and description but the old vendor code and vendor description. Since it's the vendor code and description that print on the PO, it makes for a confusing situation.
