Material Master Volumes / Sourcing Cockpit / PPS

Question

Hi,
I am currently working on an SRM + ERP (SRM 6 SP0 / ECC 6 / PPS1) implementation for the French State. We are doing a study on the feasibility of using direct procurement functionalities in SRM (sourcing cockpit etc).
Minisitries such as the French MOD however appear to have very large material master repositories.
Order of magnitudes, including clean up, reach the millions easily, so I have a hunch we can encounter performance problems.
How many different material numbers (ballpark) is it conceivable, technically, to put into one client knowing that:
1. we have to have all the materials in ECC and in SRM (regular replication),
2. we expect to have anywhere between 40 and 200 plants, each having 3-5 warehouses,
3. we will have about 25 company codes,
4. MRP functionalities will be very low (min max quantity, no BOMs),
5. we will not sell these materials,
6. we don't want to put WM in place,
7. transaction volumes expected - 1000 POs a day, each with at least ten line items,
8. we only do POs in SRM (GR IR are done in ECC),
9. we have specific developments such as systematic account determination in ERP (using T030 table) or a battery of different controls upon ordering the PO.
In my opinion, ERP tables such as MARC may have too many entries for a million or more materials to be used in our instance. Anyone can confirm this is a logical cut off point?
Also, we do not have MDM. Would this change the ballpark figure?
Thanks a lot and best regards
Mathieu

Answer 1

Wrong assignment of P org with P grp is the route cause, found the error and rectified which is working fine.
