Who generates Invoice Number if using IS web?

If a non-migrated airline uses IS WEB to reject a billing from a migrated airline, how will the Invoice Number be generated? Is it the airline who key in the Invoice Number directly on IS WEB, or SIS will generate Invoice Number after (or before?) rejection memos being entered?

If Invoice Number is generated by SIS, how does SIS avoid the possibility of duplicate Inv Number with this airlines’ internal system?

Example

Assuming XX is non-migrated and YY is migrated. During the time between Sep 2011 and Mar 2012, XX may reject YY in two ways in the same billing period. One is via IS-WEB for the YY’s billings from SIS, the other is paper rejections to those billings before SIS.

So, how do you avoid duplicate Inv Number from XX to YY?

If such a case takes place, what will ICH do? What will be shown on Form 1, (consolidate them or list them as two) ?

Dear Binbin,
SIS does not generate Invoice Numbers. Regarding your question, Invoice Numbers have to be populated when the rejection is made in IS-Web.
 

ICH will have a duplication detection functionality during the migration period in order to catch invoices being submitted to SIS and ICH via F12 at the same time.

 
Best regards
