Hi Magnus!  We have another issue also related to interest/fee voucher creation in Visma.NET This time its account specific, as it works fine for one of our customers, but does not work for the other.  We suspect its some setting in Visma.NET that isnt active in account that gives error, but we havent been able to figure it out.  Here is the error message we get:  {"message":"VismaId: f948dfa5-350c-49c7-bdf9-5e40729a2804. Error creating document. Error: TaxCategoryID '0' cannot be found in the system."}   Is this what we must do?  1. Check the customers Vat Zone - Get /controller/api/v1/customer/{customerNumber} 2. Get the Vat zones applicable Vat Id's -Get /controller/api/v1/vatZone/{vatZoneId} 3. Get the invoice lines Vat categories applicable Vat Id's -Get /controller/api/v1/vatCategory/{taxCategoryId} 4. The Vat Id needs to be a value found in both lists. - Get /controller/api/v1/vat/{vatId} Can you point us towards where to set up the Visma.NET account so its possible to export to it?  ...
