CreateCustomerWithNonBlockedCustomerCategoryWithFreeGiftsAvailable is a helper function that creates a customer with a non-blocking customer category set, and it's implemented as follows:

local procedure
    CreateCustomerWithNonBlockedCustomerCategory
        WithFreeGiftsAvailable(var Customer: record Customer)
begin
    LibrarySales.CreateCustomer(Customer);
    with Customer do begin
        Validate(
            "Customer Category Code_PKT",
            CreateNonBlockedCustomerCategory
                WithFreeGiftsAvailable());
        Modify();
    end;
end;

Note that, like our previous helper function, CreateCustomer (see test examples 1 and 2), this test function also makes use of the standard CreateCustomer function in the standard library LibrarySales codeunit (130509).
