National Product Catalogue - Message Integrity Guidelines v1.0

Retaining the integrity of the message is critical to e-Procurement as any compromise in integrity leads to the whole process being brought into question. Similarly, it is important that the message is received intact by the intended recipient. This guideline describes processes and activities that will assist in ensuring the integrity of the message, and steps to take if the integrity is compromised or the delivery process does not function correctly.

As part of that, it also describes the stages involved in e-Procurement messaging from initiation of the business document through to completion of processing by the receiver and how integrity will be retained throughout the process.
