In  the DBS S4HC competence center integration PS session, some customer or partner will  ask how to call odata api  in s4hc  by java code .  I want to take this oppotunity to show the simplist way to do this .

The assumption is that the reader had already known how to create communication system, communication user and communication arrangment in s4hc . Known how to test odata api in postman .

In SAP API hub for S4HC, https://api.sap.com/package/SAPS4HANACloud?section=Artifacts , the sample code in JAVA , JS, Python etc will be listed . We can use them directly . Let me take billing document ODATA API as an example .

Step 1, get JAVA code in api hub .

Step 2, create gradle  project in Eclipse 

3 , How to get Authorization key in postman

The end .

Best regards!
