[Shopify] Test failure in UnitTestUpdateTaxRegistrationIdForVATRegistrationNo for Belgian customers

[onbuyuka]

Problem

The unit test UnitTestUpdateTaxRegistrationIdForVATRegistrationNo in Shpfy Tax Id Mapping Test codeunit was failing when running on the Belgian (BE) localization.

The test was attempting to validate a VAT Registration No. on a Customer record, but Belgian localization requires customers to use the "Enterprise No." field instead of "VAT Registration No." for Belgian customers. This triggered the validation error:

"You must use Enterprise No. for Belgian customers."

Root Cause

When the Company Information has Country/Region Code = 'BE', the Customer.VAT Registration No. field validation rejects VAT Registration numbers because Belgian regulations require the use of the Enterprise No. field instead.

Solution

Added a condition in the test to detect when running on Belgian localization and handle it by:

1. Setting the customer's Country/Region Code to 'DE' (Germany) to bypass the Belgian-specific validation
2. Regenerating a valid VAT Registration No. for the German country code

Changes

• ShpfyTaxIdMappingTest.Codeunit.al: Added conditional logic to handle Belgian localization in UnitTestUpdateTaxRegistrationIdForVATRegistrationNo test

if CompanyInformation."Country/Region Code" = 'BE' then begin
    Customer."Country/Region Code" := 'DE'; // VAT Reg No. not allowed for BE Customers
    Customer.Modify();
    NewTaxRegistrationId := LibraryERM.GenerateVATRegistrationNo(Customer."Country/Region Code");
end;

Fixes AB#618120

are we then losing code coverage here in BE?

Consider moving the code into CreateCustomerWithVATRegNo
