You need to create a address id to the supplier.

Hi Lisa,

One time supplier’s address needs to be specified when the invoice is created. 

You can select RMB in the invoice and select..’One-time Specific Information’

Then define the relevant address details.

After this you should be able to Authorize the invoice for payments.

Hope this helps.

Hi Lisa,

If you are planning to use this supplier for frequent purchase transactions, it might be hard for you to maintain the record as one-time supplier. The idea of one-time functionality is to provide a master supplier to record one time purchases (less frequent), because there is no point to create a complete supplier master record in your AP, if you are not dealing with the supplier again. You can create a single one-time supplier and keep addresses separately for one time purchases. Under single supplier, you can keep bank accounts of the different supplier. So, one-time supplier will act as a master (dummy) supplier.
