ISPG v3.2 chapter 5.10 discusses 3rd party invoices. A few questions...
1. Assuming an invoice has been raised by a 3rd party, what invoice numbering logic would be adopted? There may be a risk this could lead to invoice numbers clashing with one already used by the carrier itself (or vice versa)? So, how can the billing carrier ensure it complies with the requirement to generate unique invoice numbers across all billing types (Pax, Misc, Cargo, UATP) in a year?
2. If 3rd party invoice is from IATA for Call Day adjustments, can we still download the Call Day Adjustment Report from ICH-WEB in order to manually add account postings? Or will the IS-XML file be the only CDA report we will receive under SIS?
3. Whilst asking about ICH-WEB, please can you confirm if any of the ICH-WEB functionality will be removed after we have migrated to SIS?
Thanks, Russell (BD)
