Re: Attaching Client's PO to Invoice We have been hoping this would become available since the addition of attachments to Purchase orders. This would be fabulous - and since already applied to POs surely not a difficult add on to Invoices Please action ASAP :) Duplicate Purchase order number This morning I created a new purchase order, ie 00024196 but while i had the PO open and was still writing in the order, another user was able to create a new order with the same number 00024196 (on purchases register screen we both clicked "NEW PURCHASE" allocating the next available number When i went to send my PO to the supplier the PO number changed to00024197 Why did thePO number i was already using still come up to them as the next available? And how can the PO number be locked to all other users as soon as it is opened/allocated I cant see anything in the SET UP menu to lock it Solved
