With Parameter option not working for unmanaged RAP

[Rahuldeshmukh]

Hi All,

I am calling RFC FM from unmanaged RAP as below : 

io_request->get_parameters( ) - having empty values when I run the preview of service. 

I am providing values - Matnr , Comp code & Batch in the preview fiori selection screen.

But when I run the through gateway - using URI - /sap/opu/odata/sap/YRCXXX/YRFC(im_matnr='2013559',im_plant='1000',im_batch='1003045037')/Set

io_request->get_parameters( ) - has paraemeter values and fetches records from RFC.

preview probably won't work.

try to create an app to consume the service.
