Hi All,
I started developing a oData gateway service in Gateway system which is connected to ERP backend system.
Initially I would like to use the Gateway service as Wrapper. I have to pass few input parameters like UI5 launch pad login user id, date, selected value from the drop down.
The below are the steps I have done so far, stuck here and need some input and help here.
1. with the help some blogs I able to create a project and import the RFC. All input parameter fields I have choosen as keys shown in the picture and mapped. Out put parameters also mapped. I just need a read operaion with hard coded input parameter values as part of the oData testing in the first step. When I run the service with these values I have expected to see some data in the XML format But I am getting some errors when I run the service in SAP NetWeaver Gateway client.
The query , I have passed in SAP SEGW client:
/sap/opu/odata/SAP/ZNY_PT_ARQ_ACCOUNTS_GET_1_SRV/TimeAccounts1Set(ImEndda='9999-12-31T00:00:00',ImModus='R',ImPernr='12868',ImSelBegda='2014-11-21T00:00:00',ImSelEndda='9999-12-31T00:00:00',ImSelPernr='12868')
