I am working on a POC currently where I need to call a BAPI inside S/4HANA On-Premise from a cloud application using Java. For this I am using SAP Cloud SDK.
For initial setup I followed these steps: https://developers.sap.com/tutorials/s4sdk-setup.html
I am trying to call BAPI_COSTCENTER_GETLIST1 from my application.
Here is the code snippet:
final BapiRequestResult resultGetCostCenters = new BapiRequest("BAPI_COSTCENTER_GETLIST1")
.withExporting("CONTROLLINGAREA", "BAPI0012_GEN-CO_AREA", "0001")
.withTable("COSTCENTERLIST", "BAPI0012_CCLIST").end()
.withTableAsReturn("BAPIRET2")
.execute(destination);
And here the declaration of destination variable:
Map<String, String> destinationProps = new HashMap<String, String>();
// Added a sample destination name. Solved NoSuchElementException error.
destinationProps.put("Name", "SampleDestination");
destinationProps.put("URL", "<system_url>");
destinationProps.put("Type", "HTTP");
destinationProps.put("Password", "<system_password>");
destinationProps.put("Authentication", "BasicAuthentication");
destinationProps.put("User", "<system_user>");
final Destination destination= new DefaultDestination(destinationProps);
But from execute(), one exception in being thrown which says
java.util.NoSuchElementException: No value present
Here is the complete stack trace
java.util.NoSuchElementException: No value present

I assume I am missing something very basic in it. Or probably I am doing it completely wrong. I could not find any well documented tutorial on this topic. So please correct me where I am going wrong.
Thanks in advance.
