Hi Experts,

I have one calculation view with 4 input parameters and it return one table as output.

I have consumed it in a .xsodata file. when I am exposing it with metadata as below its working fine.

xxxxxxxxxxx/TestXS.xsodata/$metadata.

but if I provide input parameters as below,

xxxxxxxxxxxxxxx/InputParams(param1='val',param2='val',param3='val',param4='val')

it throws the below exception

<messagexml:lang="en-US">Service exception: [2567] network error</message>

My odata definition is below

service namespace  "XXXX"

    {

   "XXXX.DATA_MODEL::Test_Calc" as "TestXS"

    key generate local "ID"

     parameters via entity "InputParams";

    } 

Please assist me for this.

Thanks in advance.
