Passing Parameters in a process model in Appian

The process parameters accept a dictionary. The key should be the exact variable name and the value should be ri!selectedSuiteName. So it should be something like 

a!startProcess(
  processModel: cons!ACC_PM_COMMENT_ON_TASK,
  processParameters: {
    selectedSuiteName: local!selectedSuiteName
  }
)

I have tried the same but I don't know why it's giving me warning as invalid process parameter, how to fix this ?

That is fine. But are you able to trigger the process when you click on it? Is the new instance generating?

Hi ,

You need to parameterize the process variable as Yes when you are triggering the Process model from the Interface

I didn't get it. How to parametrize the process variable as yes ?

The field "Parameter"

Go to Properties tab where you add process variable and when you add  process variable then there are four checkbox will be visible then you have to select the 1st checkbox(Parameter) and you are good to go.
