SAP EWM 9.5 Integration settings with SAP ERP or SAP S/4HANA

Objective –

To provide integration steps for SAP EWM and SAP ERP or SAP S/4HANA

Overview –

We will go through in details of EWM integration settings in S/4HANA 1909.

SAP EWM communicates with other applications of SAP S/4HANA via queued remote function call (qRFC).

 

Settings in SAP ERP (or SAP S/4HANA) for SAP EWM Integration – 

Setting Path Details
RFC User Creation Tools → Administration → User Maintenance  → Users Create RFC user with the help of BASIS team following the EWM 9.5 roles and authorization guide (Source provided in the reference section)
Define RFC Destination to SAP EWM Tools → Administration   → Administration   → Network → RFC Destinations (SM59)

1.  Create a new RFC destination with naming convention as <EWM System Name>CLNT<client> for example EWMCLNT100

2.  Select the connection type as ABAP System i.e. 3

3.  In technical Setting tab, enter Target Host and system number as message server and instance number resp. of SAP Logon system

4.  In ‘Logon and Security tab’, enter the userid and password of RFC User created in step 1

5.  Check if the connection is established by clicking on ‘Connection Test’.

6.      Verify if logon with the userid and password is working by clicking on ‘Remote Logon’.
