Invoicing of Purchase Orders

If the Charge Type on the Job has the option 'Billing from PO' ticked, then it is assumed that the user wants the option to invoice Purchase Order lines for which an invoice has yet to be received from the Supplier.
These lines are then included in the transaction list for invoicing.
Purchase Order lines are subject to the same Preview process as job transactions, if Previewing is being used.
With no previewing the Purchase Orders included are those with a PO Date less than or equal to the Invoice To Date. Using the 'Include Futures' selection option will include all later dated PO's.
When a PO Line is invoiced to the Client under this process it is flagged with the Invoice No. When the Suppliers invoice is subsequently processed against the PO, this AP Invoice, and its associated Job Transactions, are also flagged with the Invoice No from the PO indicating it has already been invoiced to the Client, and on what Invoice No. It cannot therefore be invoiced twice. Note that the Selling value of the transaction remains at the selling value of the PO line, even if the supplier's invoice came in at a different value to the PO.
