Interaction/Services from FS-PM to PRODUCT Engine system

Question

Hi All,
While debugging the new business i went through the class /PM0/CL_APH_PM_CALCULATION_PRO and the adapter Interface /PM0/IF_APR_PM_ADAPTER_PRO and got some basic understanding on how a FS-PM system interacts with Product Engine. Also Product Engine interfaces are assigned to corresponding classes at Policy and Contract level only.
Now my queries are as below. Kindly provide more information on these.Appreciate your help at the earliest.
1) All I have understood is that while using PRO/msg.Pm services in a TMF, A Method CALL_IM_INDIVIDUALLY sets the parameters to request data from PRO system and we handle the results using the method HANDLE_RESULTS_IM. But inside this method it is getting the data at a high level (either Policy or Contract) it is using the method "call_pcmodcontract". When i need customized fields at the Insured object level,Premium payer level which is at lower level which methods i can use.
2) Are these methods /PM0/IF_APR_PM_CALCULATION~GET_RESULT_* and /PM0/IF_APR_PM_CALCULATION~PC* are like getters and setters(Request and Response) Methods at PRO system ??
3) If i need to get the customized fields information from PRO system usually which methods i need to call.(Need more information on this).
4) Explain the usage of these methods PCACCOUNTREPVAL,PCADJUSTMENT,PCMIGRATION,PCMODCONTRACT,PCRATING,PCREVERSAL.
5) Usually i see most of the time that only these methods are implemented PCRATING and PCMODCONTRACT. Any Specific purpose of these methods ?
Appreciate your inputs on the above at the earliest. Thanks !
Best Regards,
