Production Process in IS Retail

Hi Experts,

My client having business scenario like manufacturing plant and own Retail chain.

Is it possible to achieve both Manufacturing scenario and Retail in same IS retail system or do we need separate server for manufacturing (ECC) and separate for IS?

If manufacturing possible in IS retail, BOM/Routing creation are same as ECC or different.

Please any one provide the step how to achieve production process in IS retail.

Thanks in Advance.
