Hi Madan,
It's completely depends on client requirement.As per your requirement you need to use PI industry.Which is most feasible for your requirement. There is big difference between PI & discrete mafng master data.
Pls check Below points :-
1.In master recipe you can do MQC & coproducting costing which is not available in routing.
2.You can use order approval in PI which is not available in DM.
3.You can use advance fucntionality like PI sheet & X-step.
Please share your business requirement so that we will suggest you feasible solution.
