Hello Renjith,
From functional point point of view, you need to understand at which level is the planning performed. It will help you in understanding if the new location (plant) needs to be configured as planning plant.
From configuration point of view, you will have to do the below basic settings in SPRO
1) Enterprise Structure -> Definition -> Plant Maintenance -> Maintain maintenance planning plant
2) Enterprise Structure -> Assignment -> Plant Maintenance -> Assign maintenance planning plant to maintenance plant
Apart from above mentioned setting, their are many other paramters which you will require to set in SPRO. Another important thing would be Order Type; if you intend to use the existing order type, then, you will have to extend the order for new maintenance plant else you can configure a new order type.
Cheers!!
