I intended to use NamedTypedValue to work with the parameters but eventually I still need to execute the function.

Another option since you mentioned the public API: forum.appian.com/.../TypedValue.html

Thanks Sathya but I meant to ask that whether it is possible to call ANY existing expression function using the Appian public API e.g. using 'reflection'.

Bilal, a scalable approach would be to expose the rule via a webAPI and call it from where you require the rule to be executed. WebAPI's are available as of Appian 7.9
