When you submit a transportation tender, it's added to the Outbound message queue if an applicable document flow exists with direction Outbound and type Transportation tender. When this record is processed, the custom 'Transportation tender to Carrier' (204) message runs. As a result, this message gets the data from the transportation tender as defined in the outbound message queue record, and creates and sends an EDI tender message file to your carrier.
Set up a custom 'Transportation tender to Carrier' (204) outbound message with a:
Source connector of type D365 F&SCM.
Source document of type D365 F&SCM. It should get the data from the Transportation tender in D365 F&SCM.
Target connector of your choice to exchange files.
Target document for example of type XML or JSON.
