Summary

Do we have document on how we can use Supplier Punchout solution using CMK & OBN(OSN)

I would like to know what all things we need to keep in mind while implementing supplier punchouts using CMK & OSN.

Are there any documents available for CMK messaging?

Do we need to use SOA for CMK messaging? Is the knowledge of XML sufficient to implement SOA web services used for collaboration messages?

Do we need to use BI publisher for Procurement notifications exchanged via collaboration messaging framework?

We want to understand the solution from technical angle?

Would appreciate inputs on same.
