Multiple Rows using Json Input from PostMaster

Hi,

New to SAP HANA Odata servicess, I am trying to insert multiple rows using POST method from POSTMASTER in below formats

1. Json

2. XML

When I Insert multiple rows using Json object, i get below error

{

    "Odata": [

        {

            "MY_COL1": "Sadsad124511",

            "MY_COL2": 124511

        },

        {

            "MY_COL1": "Sadsad124512",

            "MY_COL2": 124512

        }

    ]

}

Error:  <message xml:lang="en-US">Resource not found for the segment &#x0027;Odata$batch&#x0027; at position 0.</message>

I can insert single entries using Json

        {

            "MY_COL1": "Sadsad124511",

            "MY_COL2": 124511

        }

I have exposed table ZTRANS with two columns MY_COL1(String) MY_COL2(Int) as ODATA service, my service definition is as below

service  {

   "P0_MAPPING"."ZTRANS" as "Ztranslation";   

}
