Hello Sagar,
PP Functionality will depends on the
1.Material master (MRP1 ,MRP2,MRP3,MRP4 and Work scheduling view)
2. BOM
3.Work centers
4. Routing
Basically in MRP1: MRP Type and Lot size will play a major role i.e. How the planning has to happen and how system will generate the praposals
please refer the below thread for better understanding

MRP2 : Procurement type, Inhouse production time and schedule margin key and planning calendar will play a major role (please read individual field usage with the help (F1)
MRP3: Strategy Group and Availability check will play a major role
Please refer the below thread for better understanding of different planning strategies and functionality

MRP4 : It depends on the business requirement i.e. for REM and PV usages we will use the MRP4 View
Work scheduling View : Production scheduling profile (Auto GR and Auto release of the production order), Serial number profile
Suggesting you to read the each field functionality through F1 and try to search in google how to use and practice the same
