Is SCM IDES needs to integrate with ECC IDES to practice EWM component


To practice EWM component, Should I integrate both SAP systems (SCM 7.0 EHP1 IDES and ECC 6.0 IDES)?

I am thinking that i have to install both SCM 7.0 and ECC 7.0 SAP systems to work on EWM component. Am I correct? If I am wrong how best i can sort out this issue.

Please give me a suggestion. Finally requirement is that I have to practice EWM (Extended Wherehouse Management). I hope you understand my requirement. Please get back to me if you don't understand my question.
