SAP MDM Catalogue to be used in ECC

Hi Gurus,

Please give me your expert advise on the issue which i have explained through the points below:

1.Presently ,we are using MDM catalogue for SRM requisitions.

2.In future, there is plan to implement Plant Maintainenace module ,so the requisitions coming from this module will be handled in SAP ECC.Hence MDM catalogues will used in ECC as well.

3.We do have different contracts in ECC and SRM.So users accessing MDM catalogue in ECC should be be able to see the contracts of ECC only not of SRM and vise versa.

4.Herce there arises the need to segregate the data inorder to differentiate the data sets seen in SRM & ECC by creating catalogue views.

Can you please guide me on necessary configurations to be done in MDM to make the above happen?Please let me know if you need any further information on this.

Thanks & Regards,

Niti
