Alternative Payment Parameter

[dave5105]

Hi

Im trying to make an eBill QR-Code with your generator. Ist this possible and how?

I can't figure out how to deliver the last part mentioned as (Alternatives Verfahren Parameter - AltPmt)
The SWICO structured BillInformation is correctly printed and coded, but I need this addiotional line
to make it compatible for eBills.

It's described on Page 6, chapter 3 here:
https://www.ebill.ch/dam/downloads/qr-code/d0543-de-01-spez-nutzung-alternatives-verfahren-ebill-swiss-qr-code.pdf

Would be grateful for some advise/help/examples

The SWICO bill information and the eBill information use different parts of the QR bill: SWICO information goes into the structured reference, and the eBill information goes into the alternative schemes.

I haven't tried it, but it should be possible like this:

bill.setAlternativeSchemes(new AlternativeScheme[]{
    new AlternativeScheme("eBill", "eBill/R/41010560425610173")
});

Let me know if it works.

Thank you for the advise.
I tried but failed.

I don't know whats wrong with the AlternativeSheme List. Your proposal throws errors before and when compiling.
Maybe you will figure out something with the whole code. The var Typ and eBillInfo hold the info's, "Mitteilung" contains the \S1...

It's difficult to say what's wrong in your code. There is nothing related to alternative schemes. Use this code as an example:

        // Setup bill
        Bill bill = new Bill();
        bill.setAccount("CH4431999123000889012");
        bill.setAmountFromDouble(199.95);
        bill.setCurrency("CHF");

        // Set creditor
        Address creditor = new Address();
        creditor.setName("Robert Schneider AG");
        creditor.setAddressLine1("Rue du Lac 1268/2/22");
        creditor.setAddressLine2("2501 Biel");
        creditor.setCountryCode("CH");
        bill.setCreditor(creditor);

        // more bill data
        bill.setReference("210000000003139471430009017");
        bill.setUnstructuredMessage("Abonnement für 2020");

        // Set debtor
        Address debtor = new Address();
        debtor.setName("Pia-Maria Rutschmann-Schnyder");
        debtor.setAddressLine1("Grosse Marktgasse 28");
        debtor.setAddressLine2("9400 Rorschach");
        debtor.setCountryCode("CH");
        bill.setDebtor(debtor);

        // Swico information
        SwicoBillInformation info = new SwicoBillInformation();
        info.setInvoiceNumber("10201409");
        info.setInvoiceDate(LocalDate.of(2019, 5, 12));
        info.setCustomerReference("1400.000-53");
        info.setVatNumber("106017086");
        info.setVatDate(LocalDate.of(2018, 5, 8));
        info.setVatRate(BigDecimal.valueOf(7.7));
        bill.setBillInformation(info.encodeAsText());

        // eBill alternative scheme
        bill.setAlternativeSchemes(new AlternativeScheme[]{
                new AlternativeScheme("eBill", "eBill/R/41010560425610173")
        });

        // Set output format
        BillFormat format = bill.getFormat();
        format.setGraphicsFormat(GraphicsFormat.SVG);
        format.setOutputSize(OutputSize.QR_BILL_ONLY);
        format.setLanguage(Language.DE);

        // Generate QR bill
        byte[] svg = QRBill.generate(bill);

It producdes this output:

I've just realized the problem. Your using the .NET version but have started a discussion in the Java section. (I'm aware it can be confusing.)

In .NET, it looks like so:

Bill bill = new Bill
{
     ...

    AlternativeSchemes = new List<AlternativeScheme>(
        new[] {
            new AlternativeScheme { Name = "eBill", Instruction = "eBill/R/41010560425610173" }
    })
};

[dave5105]

Thank you very much for you help. I had another issue, not sure actually why, but I could solve it myself.
It's related to eBill and maybe also Postfiance specific, but the eBills are rejected as Invalid if there is an UnstructuredMessage present...
This element/field has to be empty if the AlternativeShemes are used. Achselzuck

Just in case someone has something similar...

And sorry for having posted it in the wrong place. I hadn't realized it either.

[manuelbl]

I'm not aware of any such constraint but I will do my own investigations.
