I am looking to import file attachments from our legacy system to D365 F&O for various documents (Customer, Vendor, Sales order, Purchase order, Return order) during conversion/go live. I understand that I can export docuref attachments to a package format by way of DMF for any of the provided document handling data entities, and then import them because the resource folder will then contain the file to import. In my case, I do not have the file attachment in D365 already. What is the procedure to import docuref file attachments using DMF when the files do not already exist in D365? Is it a manual manipulation of a package export, resource folder and the manifest?
Thanks,
Steve
