When there are several cost rows on one invoice that should be approved by different people it normally takes long time for the invoice to get handled. One problem is that the whole invoice gets locked when one user opens it, it would be better if only specific cost rows could be locked depending on which user that opens the invoice.
It is also annoying that I always, as soon as I open the inbox have an invoice marked and thereby locks it for other user to handle. If I open the invoice and realize I need to check something before handling my cost row and do not close Medius while doing that I have locked the invoice for my colleagues that might be ready to handle their part. I think I should have to make some sort of action on the invoice before it gets locked for others to work with.
