VAT number validation fails since last week

Good morning forum,

Start last week we have an issue with the VAT validation. When executed (by entering a valid VAT in a customer card) we get an XML error.

It states that the call is not successful because System.Xml.XmlDocument.Load has failed. I've looked at the operation of the service http://ec.europa.eu/taxation_customs/vies/services/checkVatService and that seems all in order when called from Postman. I looked also at the template that is used for this call, but can't find a way to see the actual template that is used in this call.

Do any of you experience the same problem?

From some days the service doesn't accept Content-Type multipart/form-data; charset=utf-8.
The problem can be fixed temporarily as follows:

[EventSubscriber(ObjectType::Codeunit, Codeunit::"VAT Lookup Ext. Data Hndl", 'OnSendRequestToVatRegistrationServiceOnBeforeSendRequestToWebService', '', false, false)]
local procedure VATLookupExtDataHndl_OnSendRequestToVatRegistrationServiceOnBeforeSendRequestToWebService(var SOAPWebServiceRequestMgt: Codeunit "SOAP Web Service Request Mgt."; var TempBlobBody: Codeunit "Temp Blob")
begin
SOAPWebServiceRequestMgt.SetContentType('text/xml; charset=utf-8');
end;

Hi Stefano, I understand that you use this code to overrule/amend the existing code that is triggered by this event. I'm fairly new to BC programming but I think you put this in an AL extension and load it in Dynamics?

Yes you need to create an AL extension to apply the above fix.

Microsoft is aware of this problem, no ETA for an official fix now (so recommendation is to fix it as per my answer above).

Hi Stefano,

thx for this workaround. Unfortunately this Event doesn't exist in older BC OnPrem versions. :(

At least I can fix this for my Saas Customers. ;)

Solution for older NAV versions is described here (it’s basically the same):

We have on BC V18 OnPrem Customer. The mentioned Eventpublishe doesn’t exist and we don’t want to customize the Base App.

Good afternoon;

Exact same issue and message when trying to check VAT for EU (worked before) both for customers and vendors cards.

The issue was forwarded to our BC support partner, hoping for a quick fix, because we fear it may jeopardize the sepa paying slip.

thanks,

For some bc on prem versions ( like v16 ) where the event is not available but its not NAV which is easier to modify the base app , is there any other way to temporarily fix this bug without having to modify the base app?

Adding NorthW, yzhums in the conversation as well!

Hi, I'm sorry I haven't tried it.
You can copy the original button and create a new one. But since some local methods can't be called, I don't know if this is possible without trying it.

I hope this will give you some hints.

Thanks.
