I have a report with XML Web service as data source. The output of XML Web service will be used to fill a multi-value parameter(Drop-down parameter) with values. As Mutli-value parameter does not allow null values, if the XML web service does not return anything, will it be possible to have some dummy value added in the XML query so that when the XML web service does not return any data, this dummy value can be used to fill the drop-down parameter. Kindly provide your inputs on this.
