I have set up a new company with e-invoicing, ERP version 8.4 2018-01-26 build 84191204, and now

when we are trying to save an sales order, or invoice I get message Inkorrekt Bank 1 format check company settings. I can not see anything wrong in company setting regarding Bank 1.

The strange thing is that if I tick "do not send e-invoices" in customer register then it is ok
to save invoice or sales order!

Can someone explain where I can find the problem?


Thanks in advance!
