In some cases, papiNet has defined pairs of e-Documents to support this. For example

• PurchaseOrder & OrderConfirmation

In other scenarios, papiNet has defined two e-Documents to facilitate this functionality

• BusinessAcceptance, to enable the receiver to reply with a technical confirmation that the e-Documet has been received
• BusinessAcknowledgement, to enable replying with a confirmation that the e-Document has been received into the receiver's business IT system
