Hello Samara,
I have provided a brief summary of our processes below.
* PO is raised
* PO is converted to a bill when goods or services are received.
* Suppler invoice is matched to the Bill.
* Supplier invoice number is added in the field "Supplier Inv No. Refer screen shot previously provided below.
However, there does not appear to be any way to enter the supplier invoice date in MYOB.
When preparing reports of o/s supplier invoices, we MANUALLY add invoice dates in the exported Excel files.
There are no messages when matching and we are not aware of the Import/Export Assistant.
Regards,
Jeff
