VBC field is coming read-only in pick applet Query Mode

Hi Guru's,

We are creating a pick applet based on the VBC. One field is coming read only and another one is coming as editable in the query mode. We used the below code to initialize the VBC fields.

Same is working in the List Applet(With Same VBC and BS).

function Init (Inputs, Outputs, fields)

{

for (var i = 0; i < fields.length; i++)

   {

  var fieldname= fields[i];

    Outputs.SetProperty(fieldname, "");

   }

   return (CancelOperation);

}

Any advises please,

Regards
