AP - Append Multiple Receipts into One Invoice

Dear All

we are using iSupplier. we create ASN -> Receipt - > Pay of receipt auto invoice -> Interface to AP - > Created Invoice

we have a scenario, where we created a ASN. Due to bulk shipment (Say 9 containers), we created a GRN for 2 containers, costed, taken to stock for urgent delivery to customers.

At this juncture pay on receipt auto invoices creates an Invoice in AP.

Now the logistics received the remaining 7 containers and taken to stock. now when the pay of receipt auto invoice, it creates a new invoice, rather we expect it to append in the same invoice.
