OdateModel.read method passing URL parameters

Hi experts,

Can you please help.

I have a HANA calc view with input parameters "param1" defined in the model.

This model is used as my  JSON Model.

when I try to read

ODataModel.read (spath,

{

URL parameters : { select column1, column2},

filters : my filters,

success : function (oData, response)

{

},

async :true

}

)

it is throwing error as "calculation model requires parameters :required variable "

My question :- How do I pass param1 defined in the model to the URL parameters .

I would like know the syntax .

Please help

Thanks
