For EDI ordering with a vendor, you also need their Delivery Codes setting up as well as the EDI setup details.
To setup Vendor Delivery Codes:
First, you will need to ask the vendor to provide you with their Delivery Codes so you can use them when ordering via EDI.
Go into the Vendor company record
Click into the Vendor tab
You will see an area in the bottom right called Delivery Codes (In Trading Currency)
Click Add
Enter the Code the vendor has given and the Description of what this code is, such as Next Day Delivery
In the System Type drop down, you can select either Standard, Pick Wrap and Label or Direct Delivery
Set as Default - This tick box is where you can set a default delivery code for this vendor
You can also add a cost which will be pulled on to a purchase order for this vendor when chosen
