This knowledge base article will assist you with how to create a Report Parameter in XML and then how to reflect it in a Parameter Window.
The report parameter may contain multiple values in the parameter dropdown. A dropdown parameter can be used when there is a condition on an object and data needs to be retrieved based on a set condition.
Follow these steps mentioned below, which are based on filter criteria when a user wants to display multiple columns in a report:
1. Set filter criteria in a report using iVend Report Designer.
2. Now add the following code snippet in the XML file of the Parameter report.

<Parameter name="ValueCalculation" objecttype="36" caption="Values At" multiselect="false" ValidValues ="ValueCalculation"/>
<ValueCalculation>
<CostPrice>CostPrice</CostPrice>
<RetailPrice>RetailPrice</RetailPrice>
</ValueCalculation>
3. Save the Parameter XML file.
4. Import the XML and .IRT file in the iVend Report Manager.
Refer to the screen image below that illustrates the dropdown parameter.
