How to CALL procedure having DDL statements through xsjs?

Hello Experts,

I have created one procedure on HCP, having DDL statements. It works fine when I CALL it from SQL console. But getting below error while calling through xsjs:

Error while executing query: [dberror($.hdb.Connection.executeProcedure): 258 - SQL error, server error code: 258. insufficient privilege: [258] "<schema_name>"."PROC_PM_FAILURE_PREDICT_COUNT": line 73 col 1 (at pos 2633): [258] (range 3) insufficient privilege exception: insufficient privilege: search table error: [2950] user is not authorized at ptime/query/plan_executor/trex_wrapper/trex_wrapper_body/trex_query.cc:1370]

XSJS:

//Get parameters

var tx_data_query = "";

function getTxtData(){

  var txlist = [];

    var connection = $.hdb.getConnection();

    var statement = null;

    var resultSet = null;

     try{

               statement = connection.loadProcedure('<schema_name>','PROC_PM_FAILURE_PREDICT_COUNT');

               resultSet = statement('US','Missouri','Cape Girardeau County','Cape Girardeau','Baby Care','All');

     } finally {

              connection.close();

    }

      return resultSet;

}

function doGet() { 

          try{ 

                    $.response.contentType = "text/plain";

                    $.response.setBody(JSON.stringify(getTxtData()));

          } 

          catch(err){ 

                    $.response.contentType = "text/plain"; 

                    $.response.setBody("Error while executing query: [" + err.message + "]"); 

                    $.response.returnCode = 200; 

          } 

} 

doGet();
