Hi Norman,

Thanks for the error message - that is useful.

With that template layout and import information, I was successful in importing the invoice with Payables 8.1A.

Do you have the option 'Header fields on each record' selected? If so, this is a problem because you have the 'H' and 'D' portions on separate rows. Having this checkbox selected gives the error you reported. Because you (correctly) have H a dn D lines on separate rows, you should not use the 'header fields on each record' option when importing. This option is really for Excel-format files, where all the H and D fields are on the same row, and the H values are repeated for each detail.
