Integration

Interfaces to ERP (scenarios)
SAP EWM as a decentralized warehouse management component is fully integrated into the SAP SCM component. SAP EWM can also be centrally operated as an add-on to ERP, however the same interfaces as in the decentralized scenario will be active.
Communication between ERP and EWM for flow data is always taking place via  queued Remote Function Calls (qRFC ) or via Idocs (depending on the ERP release).The communication between EPR and EWM for master data is taking place via  the  Core Interface (CIF ). The interface is identical to the interface used at the connection to a remote SAP LES.

Global Trade Services (GTS)
The use of Global Trade Services serves the development of foreign trade processes and the consideration of trade  regulations. Within EWM, SAP GTS can be used to connect the delivery processing to the shipping procedure, to the storage, to the customs warehousing methods and to the SAP-GTS compliance testing.

Migration
SAP EWM provides the user a variety of different upload options for the migration. A pre-defined, easy-to-use CSV file can be used to integrate inventory, packaging specifications, storage bins and bin sorting into EWM.
