How to get Selected Choice Label in a rule input Variable

Hi,

You can use displayValue function inside your saveInto param. That way, you will be able to identify the selected label and save it into the desired RI. 
For instance, let's suppose the RI in which you want to save is 'selectedLabel'. Now please refer to the code snippet below.

a!dropdownField(
  label: "Appliance Id",
  labelPosition: "JUSTIFIED",
  placeholder: "Select the appliance",
  choiceLabels: rule!LN_Concatenate_Appliance_Customer_Details(local!userId),
  choiceValues: rule!LN_Fetch_Appliance_Based_Customer_Id(local!userId).data.applianceId.applianceId,
  value: local!applianceId,
  saveInto: {
    local!applianceId,
    ri!Servicing.applianceId.applianceId,
    a!save(
      ri!selectedLabel,
      displayvalue(
        local!applianceId,
        rule!LN_Fetch_Appliance_Based_Customer_Id(local!userId).data.applianceId.applianceId,
        rule!LN_Concatenate_Appliance_Customer_Details(local!userId),
        null
      )
    )
  },
  showWhen: ri!isCustomerCare
)

Also, you might need to explicitly cast the params of displayValue in the desired data type for ease of use. 

Thank you so much! It worked. Yes, I just needed it for displaying in text, so casting wasn't required.
