SRM Organization Structure Defining for multiple company code
We are on SRM 7.0 and implementing plan driven procurement where requirement from ECC system will be transferred to SRM system in the form of external requirement.
The issue we have, in backend ECC system multiple company code and purchase organization exist. Also the Purchasing group are not unique for each purchaser.
For e.g. PGRP (010) is used by Company code 0101 as well as by company code 0102.
For e.g Purchaser (010) creates a PR for PORG 0101 (assinged to company code 0101) in ECC system
The same Purcahser (010) creates PR for PORG 0102 (assinged to company code 0102) in ECC system
Now in SRM sytem how the routing of PR will happen, as we can only define one purchasing group referring to backend i.e. 010
Also, how the SRM org structure is to be designed considering this requirement?
How many local channel one needs to be created considering the above requirement?
