RE: how to sell items from purchase order in ax2012
It depends on whether you sometimes want an item to come into stock, or whether you always drop ship. e.g. non-stock item is one option.
If its ad hoc then why not just do a virtual receipt and shipment? If there is lot of such transactions then consider RPA to automate back to back updates of the various transactions and documents.
The physical control is what needs to be managed.
You can change address but its difficult to advise without understanding what information is passed to the vendor and when - so that he knows where to send the goods.
Does he supply your invoice or his with the shipment? " with which prices ?
We don't know the arrangement - impact of Charges, Customs clearances to do?
Who will calculate your sales tax? Do you or the vendor manage the delivery , booking in ?
Are your POs change controlled?
Does the item have any QA checks defined?
Should the purchase be part of your month end inventory close calculation?
Are there any batch control or sellable days considerations?
Will the customer comumnicate direct with the vendor re changes to order data or quantity?
How will returns be handled?
