SendInvoices TYPE_14_30 (entity self-declaration) — error 105 in dev environment

[tpharaoh]

Hi,

I'm trying to submit an expense via SendInvoices with InvoiceType::TYPE_14_30 (entity document / expense self-classification) in the dev environment and consistently get error 105:

User VAT number XXXXXXXXX is not authorized to issue invoices of type 14.x

The same credentials work fine for income invoices (TYPE_2_1, TYPE_2_2, etc).

The alternative approach — using SendExpensesClassification to classify an existing vendor invoice by its MARK — works perfectly in dev.

My question: is it a known limitation of the AADE dev environment that 14.x types are not supported? Or is there some activation/authorization step needed on the developer portal?

Reference code:

$header = new InvoiceHeader();                                                                                                                                                                                                                                             
$header->setSeries('EXP');

Thanks!

Hi, thanks for reaching out

The SendExpesnesClassification would likely work well in production environment too. I can't tell you much about 14.30.
However, I've noticed that for all my intra-community invoices, my accountant issues an invoice of type 14.3.

In this invoice the issuer is Hetzner.

'issuer' => [
    "vatNumber" => "812871812",
    "country" => "DE",
    "branch" => "0",
    "name" => "HETZNER"
]

The counterpart is me, the invoice type is 14.3 and the invoice lines are as in the image below (note that invoice lines already contain classifications):

Hetzner sent me the invoice with zero taxes (118.10) and of course wihtout classifications. My accountant issued an extra invoice of type 14.3, where he added the related tax amount and filled the classifications.

Hope that helps

So the error I am getting is simply related to dev environment? Thanks
