I have an existing AX 2009 customer looking to move to Dynamics 365. They currently use the application integration framework to generate an xml version of their sales delivery notes and invoices for certain customers. The xml is generated using the "send electronically" button on the invoice journal and delivery note journal forms and the xml file is written to a folder on the server from which it is then picked up by a 3rd party EDI provider for onward processing.
I'm trying to work out how best to replicate this in Dynamics 365. I can see that the invoice journal form has a "send" button that looks to use an electronic reporting configuration defined in the parameters. However I can only see configurations for specific country invoice formats available in LCS. For the delivery note (packing slip) the journal form no longer has a button to send electronically at all.
What is the correct way to send an ASN and sales invoice electronically in Dynamics 365?
