Dear Community 

I'm working on implementation of SAP Build Apps application low code based on ABAP on cloud odata service . 

I have created the destination in SAP BTP destination as follows : 

And I have tried to make a get call over this destination as follows : 

Unfortunatly I'm blocked and it does not work : 

I tried many workaround and it does not work . 

And samething when I used basic authentification it does not work . 

your urgent help is highly appreciated

Hi,

Please use the relative url like '/destination/EMDEMO/sap/opu/odata/sap/ZSRV_EM_ORDERS_BIND' instead of the 'https://<backend>.ondemand.com/sap/opu/odata/sap/ZSRV_EM_ORDERS_BIND'

CORS blocking due to direct calling of the url.

Thanks,

Arun

Hi Arun Jacob

I basically wanted to follow the steps in this link : SAP Build Apps – REST API Integration - Customize ... - SAP Community 

My aim is to call function import for SAP ABAP cloud odata services and even if I correct it for the Get Part , I'm not sure how to proceed for function import . 

Thanks a lot for your quick reply 

Regards

In the metadata of the service, function import already implemented? Like '<FunctionImport Name="MyFunction" EntitySet="..." ReturnType="..." m:HttpMethod="POST" />'?
