Hi @avinashdubey103 ,

You can use below script i have tried in pdi its working.

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }

   var regexp = /^[1-9]\d*$/;

if (!regexp.test(newValue)) {
    alert('Please enter a positive numeric value greater than 0.');
    g_form.setValue('get_validation', '');
}




   
}

Please mark it as solution proposed and helpful if it serves your purpose.

Thanks,

Anand
