It is possible change the initial numbering in Global Intercompany transaction source ?

Dears All,

As I put in the discussion title, I will like know if is possible change the initial numbering in Global Intercompany transaction source, this necessity born because we are using AGIS for to do intercompany invoices, in the time when we run the Payables Open Interface Import program we are getting the next error "Duplicate Invoice Number", it is because we have one invoice (Manually created) with the same operating unit, supplier, supplier site and invoice number than the invoice generated via AGIS. We generated an analysis and we find that we have the same numeration for manually entered invoices
