Getting this error "The valid account classes are Rev, Freight, Tax, and Rec. (UNEARN)

Hi,

We are trying to upload AR invoice using FBDI template.

We are passing the REV and UNEARN Account classes for the invoice.

But the invoice upload is failing with the below error -

"The valid account classes are Rev, Freight, Tax, and Rec. (UNEARN)"

Can you please help us with this issue.

Thanks,

Shikha Singh
