How are Payment Terms defaulted in Copy Orders?

Payment Terms are set on the PO based on the payInDaysNumberOfDays passed in the PO cXML. Below set of files are part of the Payment Terms data in Ariba (can be obtained by exporting).

1. PaymentTerms.csv
2. PaymentTermsStep.csv
3. PaymentTermsStepDetails.csv

Values from the PO cXML must match the values from PaymentStepDetails.csv file for the Payment terms to get loaded in Ariba P2P. Format for Payment Terms in the cXML:

<PaymentTerm payInNumberOfDays="30">
<Discount>
<DiscountPercent percent="3.000"/>
</Discount>
</PaymentTerm>

Detailed information on setting up the payment terms are discussed here: How do I edit payment terms in Ariba Administrator?
