what feature of bitcoin would an ERP system use? if the idea is just "Oracle NetSuite, but denominated in bitcoin," I think Netsuite already has you covered: bitcoin is supported as a foreign currency...
What I mean is: ERP systems that run on top of Bitcoin (Layer-1) as a Layer-2/3. I don't know if this is technically possible, but if a company could run it's entire enterprise off of a Bitcoin-based ERP system, perhaps through some kind of mining-server (?) - I'm sure company's would be happy to stop paying to exorbitant fees (from SAP or Oracle) for a "ERP for Hashing BTC" arrangement. Again, I don't know if this is even technically possible - but it would be a great alternative for many companies.
