Dear Susanne,

There are 3 places where you have to populated Organisation ID, one is at the header of the file:

<TransmissionHeader>

    <TransmissionDateTime>2011-05-19T10:30:32</TransmissionDateTime>

    <Version>IATA:ISXMLInvoiceV3.2</Version>

    <IssuingOrganizationID>098</IssuingOrganizationID>

    <BillingCategory>Passenger</BillingCategory>

  </TransmissionHeader>

  <Invoice>

In this case Air India is sending the file.

<Invoice>

    <InvoiceHeader>

      <InvoiceNumber>BRPXAI1Y11</InvoiceNumber>

      <InvoiceDate>2011-05-19</InvoiceDate>

      <InvoiceType>Invoice</InvoiceType>

      <ChargeCategory>Pax Non Sample</ChargeCategory>

      <SellerOrganization>

        <OrganizationID>098</OrganizationID>

And in the second place at the header level of the invoice, for the from to billing entity.

So in your case you will need to populate twice with the billing entity, for those two fields.
