Thank you for response Evita, Unfortunately when I include my property in braces in this way I got an error: .pySteps(4).pyStepsCallParams.Field: Invalid expression or reference: line 1:0 no viable alternative at input '{' {.propOrig}" Regards, Dmytro

Hi Mahesh, Thank you for the sample case you've created. I am able to hardcode the property name in the Field field like ".Property1" in your example. But I want to set it dynamically, depending on input parameter. Please suppose I have an input parameter in this Activity "propertyName" of type String. I cannot directly set it in the Field as "param.propNameOrig", such attempt will throw an error: "The method addMessageWithKey(String, String) is undefined for the type String". But I'm able to get this property as ClipboardProperty and its reference as a String in the previous Java step like: ClipboardProperty prop = workPage.getProperty(tools.getParamValue("propertyName")); String propRef = prop.getReference(); Now how I can pass this property in Field? I can't use local or param for prop becuase of its type. I guess I need to use some function like @Utilities.getPropertyByItsName(local.propertyName), but I cannot find the appropriate one.
