Hi Juergen,
I was trying my hands on SAP EWM using this installation guide: http://help.sap.com/SCENARIOS_BUS2010/helpdata/EN/48/eb3ced3119740ee10000000a421937/frameset.htm
Here it has a section on model and planning version management. It has refered to the transaction /sapapo/mvm. Can you please guide how to proceed ?
Thanks and Regards
Oritra
