now having this same issue, with a different file, different saved CSV Import. Same error. 🤔

To confirm, are you using the "Multiple Files to Upload" import method?

Nope, single file.

Do you have one of the required fields for creating new Vendor Bills mapped? ("Doc. No." or "Invoice #", etc) Transactions CSV Import Error: You must map…>

Yes, mapped correctly

did you have it edited by someone else aside from you? i get this error sometimes when it's processed and saved in excel by other folks. Excel does something funky to the csv and it won't work right.

I created a completely clean csv from scratch. Twice.

@Jacob Jackson I'm seeing a similar issue this morning. CSV imports that have always worked now say it requires the ID or External ID when I used to be able to import to the document number
