EDI Standard used in SRM-SUS for Purchaser - Vendor Document Exchange?

Hi Forum,

For exchange of electronic documents like ASN, PO, PO Response, Confirmations etc. between buyer and seller, which EDI standard is used in SRM-SUS?

Say there are two different vendors one from North America using ANSI X 12 as EDI Standard and other from Europe using EDIFACT, how is the document exchange handled for these two different seller / edi standard in same SUS system?

Thanks,

Anubhav
