Hi
PTC ESI will support integration between Windchill ,SAP and Oracle Apps only. ESI will not support MES.
I heared PTC and GE(MES) togather developing Windchill and MES intergration project. I dont know when its will be release to market!
Let us wait and see..!!
We are also doing same to same ( Windchill and MES integration) project for our customer with customization only. We are in starting phase only.
