Hello Abhi
Most of the information is in the Help Online
There is a lot of information there.
Anyway, answering your question, if the department has a phisycal storage location that manages stock, a MM storage Location must be created. It usualy happens in Surgery, Emergency and Intensive Care Units.
Please, let me know if you have a more questions, it's very difficult to explain the whole integration in a few lines
With best regards
