Planning interchangeable materials in MRP Live
As I mentioned in my previous blog https://blogs.sap.com/2017/03/24/industry-solution-functionalities-available-in-standard-s4-hana/ , several functionalities that were restricted to industry solutions are now available in S/4 HANA.
One of the most useful of those functionalities is the interchangeability of parts, that was restricted to the IS-ADEC industry solution in the past, and that can now be used in S/4 HANA. With the interchangeability of parts, MRP can together several materials that can be used to replace each other.
In the first S/4 HANA releases, unfortunately, this functionality was not fully integrated with MRP Live, which means that interchangeable materials could be planned with the MRP Live transaction MD01N, but MRP would internally use the old ABAP logic to plan them, instead of planning them with the HANA stored procedures. The positive side was that the same transaction could be used to plan all the materials, but the negative side was that the performance was not so great when planning with ABAP (note 2023766 – MRP Live/MRP Classic: Performance Information provides more details about this topic).
Now, with the introduction of the following note, planning of the interchangeable materials in MRP live is executed with the HANA stored procedures, which means a better performance for MRP live when planning interchangeable materials.

Note: If you are planning to implement this note, you should consider that there are manual steps, besides the implementation in transaction SNOTE.
If you are using MRP Live in EHP7 or EHP8 with the IS-ADEC industry solution, interchangeable materials should still be planned with the ABAP logic, since the HANA stored procedures are not yet enable to plant interchangeable materials. The following note should be implemented, in order to ensure that all the interchangeable materials will be planned with the ABAP logic in MRP Live:

Hi Caetano,
I have been looking for a possible solution but didn't get anything useful yet, I hope you can help me. Since configured the Supersession chain in S4 Hana 1610 and maintained Old and new parts via Tcode PIC01, However, PR is not generated In ATO scenario when I am running MD50, the system doesn't create PR and the same issue while running MD51 with PM.
2434791 note is already implemented at the time of go-live and MRP live is not being used yet, I tried to run but it gives a dump.
Please advise.
Thanks
Shashi
