Can we use SAP Namespace assigned to us for ECC in S/4 HANA

[Former Member]

SAP has assigned us a Customer Namespace for use in SAP ECC 6.0.

Will we be able to use same namespace in S/4 HANA too? Or do we have to apply for a new Namespace for S/4 HANA?

The S/4HANA might have a different "Installation Number". As long as the "Installation Number" of your ERP ECC 6.0 and S/4HANA system belongs to the same SAP Customer number, you can simple create the required namespace keys for the new "Installation number" in the Namespace Application.

If the "Installation Number" in transaction SLICENSE is same in both systems, you can just take namespace keys in SE03 from ECC to S/4HANA.
