Rule Input setting to null after refresh after interface gets refreshed

Question

There is an interface created which displays business elements in a tabular form, fetching details from a process report. The interface is expecting a rule input and filter the data based on rule input. 
 The issue I am facing is, once the interface page gets refresh, the rule input value is getting set to null. Any idea how to handle this scenario?

Rule inputs are used to exchange values between objects like Interface and Expression, interface and Process Model, etc. But they don't have a memory of their own. You will have to use local variables for this. 
 amikb0002 You can take a look at this documentation for better clarity - docs.appian.com/.../Local_Variables.html

amikb0002 I assume this clientName is a filter on the interface. You can use the below code as a sample to understand. 
 a!localVariables(
 local!clientName,
 rule!getDataFromProcessReport(
 clientName: local!clientName
 )
)
