As in general the interface for embedded EWM has not been changed, most of the settings for the integration between the ERP and the EWM part of an S/4HANA system are similar or the same to that of a decentral deployment.
As there is just one system and one client, the ERP logical system is assigned to that client, for the EWM part only a dummy logical system for the distribution model is required. You need an RFC connection with the same name as the logical system name of the ERP.

A business system group is required, but only the logical system of the ERP is assigned to this, and there is only one business system, which is defined as "own" business system, but is also connected to the logical system of the ERP side.
Organizational Integration
The organizational integration settings are the same as with a decentral EWM, also in this scenario an interim ERP warehouse number is required for the connection.
