DMT - Loading AP PO-based Invoices?

I know this is a rehash of existing topics on using DMT to load AP Invoices that are PO and receipt based, but I wanted to ask: Has anyone had any success in creating PO-based invoices yet in DMT using just the AP Invoice Combined template? If so, do you have templates you could share for doing this? I just saw where others have used the AP Invoice Receipt template to select receipt lines for the invoice, but I could still use what templates and order of use to run the alternative process. I’ve had no luck so far in creating a PO-based invoice due to the “Invalid Uninvoiced Receipt” error.
