How to call decision rule in interface

You can simply call the decision like below, store it into a local variable and then use that data to show in the interface.

rule!ALM_decisionRule(input1: "AKSHARA FOUNDATION" /*Desired input*/ )

Yes i tried this way but its not working 

Can you please share your code?

Can you please share your code?

a!localVariables(
  local!address:rule!ALM_decisionRule(input1: "AKSHARA FOUNDATION"),
  {
a!columnsLayout(
  columns: {
    a!columnLayout(
      contents: {
        a!sectionLayout(
          label: " ",
          contents: {
            a!boxLayout(
              label: "Donation Details",
              contents: {
                a!pickerFieldUsers(
                  label: "Donor *",
                  labelPosition: "ABOVE",
                  placeholder: "Enter the name of the Donor",
                  maxSelections: 1,
                  value: ri!donationDetails.donarName,
                  saveInto: ri!donationDetails.donarName,
                  readOnly: ri!isReadOnly
                ),
                a!sideBySideLayout(
                  items: {
                    a!sideBySideItem(
                      item: a!dropdownField(
                        label: "Organization Name",
                        labelPosition: "ABOVE",
                        placeholder: "Choose a value",
                        choiceLabels: local!address,
                        choiceValues: local!address,
                        value: local!address,
                        saveInto: ri!donationDetails.orgName,
                        disabled: ri!isReadOnly
                  
                      )
                    ),

here in place of input: "Akshara foundation" i tried giving fv!item also bt it didnt wrk

Sorry, I didn't get your full code (or) what you're trying to do exactly. But I've attached a sample of how the decision can be used.

a!localVariables(
  local!address: rule!ALM_decisionRule(input1: "AKSHARA FOUNDATION"),
  {
    a!sectionLayout(
      label: " ",
      contents: {
        a!boxLayout(
          label: "Donation Details",
          contents: {
            a!sideBySideLayout(
              items: {
                a!sideBySideItem(
                  item: a!textField(
                    label: "Organization Tax Id",
                    labelPosition: "ABOVE",
                    readOnly: true(),
                    value: local!address.output1
                  )
                ),
                a!sideBySideItem(
                  item: a!textField(
                    label: "Organization Address",
                    labelPosition: "ABOVE",
                    readOnly: true(),
                    value: local!address.output2
                  )
                )
              }
            )
          }
        )
      }
    )
  }
)

Actually here. in this code i am trying to pass the decision rule in place of choice values and choice labels so when a person selects the field he can see the options.

( In my decision rule the input1 values are me organisation name values and my ouput1 value is my taxid and my output 2 is my address) 

 a!sideBySideLayout(
items: {
a!sideBySideItem(
item: a!dropdownField(
label: "Organization Name",
labelPosition: "ABOVE",
placeholder: "Choose a value",
choiceLabels: local!address,
choiceValues: local!address,
value: local!address,
saveInto: ri!donationDetails.orgName,
disabled: ri!isReadOnly

)
),

Decision objects in Appian are meant to return specific output values based on the input value. You have designed your decision like it'll return only one output (tax Id & Address) for the given input name. So the output is always going to be a single map with two fields.

This data is not apt for passing as choice values in a drop-down. I'd recommend rethinking your design approach.

Yeah sure. Thank you
