DMT AP Invoices Combined -- "APInvHed record not found"

Trying to use AP Invoices Combined in 10.2.300 (both DMT v. 38 and v.39 released yesterday).
I keep getting the same error message:

“Table: APInvHed Msg: APInvHed record not found.”

Presumably, this was a known bug (JIRA DMT-286) that was supposed to fix the issue in version 39.
Just curious if others are using this template with success, b/c I cannot get confirmation from Epicor Support if it actually works or not.
According to Epicor, they say I have to manually create the A/P Invoice Header records first (which is not an acceptable solutions with hundreds of imported invoices on a weekly basis).

Hello Tom, dou yoy have a answer about this error “Table: APInvHed Msg: APInvHed record not found.”?

v.41 seems to be creating the headers for me though I never tried on previous versions.

Just for the record, I was receiving this error and was about to rip my hair out. I was moving the column everywhere and if I don’t follow the exact DMT column order it didn’t work. This one seems pickier than most.

Thank you for that hint! The column order was causing the issue for me as well.
