The standard D365 allows only vendor financial dimension inheritance for 1 offset expense line (when you enter your invoice on a single line).

If you create an invoice with more than 1 expense line in the same voucher (that is common), you need to populate manually the vendor financial dimension because the automatic inheritance is not working.

There is no functional or business explanation that an invoice with multiple expense lines (for the same voucher) cannot inherit the vendor financial dimensions. Most of the time, the customer create a customization to automatize this inheritance, that is not normal.

Thanks for your help.
