It an assignment Operator which Used to Be in Appian But with Modernization we have Modern Function which we use for the same Purpose .

Normally there is no drawback of it . It's just like Declaring the Own Function which we Create (any if else or any Modern Login) in the Editor with the Value

All expressions (be it process model expressions, expression rules, interfaces, etc) used to be required to start with the "=" sign, perhaps for some sign to the Appian interpreter that it would be reading expression language "code" as opposed to plaintext (edit: i just remembered that the alternative is a literal value, i.e. an integer, etc.).

That was a while ago. Over the years, as we've switched more and more to the modern GUI style expression editors (and interface editor), the "=" has become optional and, in many cases, automatically removed if left in (like in the data output code box in the process modeler). Only a few places are left where it's required / auto-added (like the data input tab expression boxes).

If you ever poke around in the expression rules of a legacy project you'll probably notice many of them still begin with a leading "=" though.

The first = symbol in your expression likely serves a syntactic purpose to maintain consistent formatting within Appian process models. It doesn't perform an actual comparison with true().

It simply says that the value you have defined for the parameter, I assume.

The first = is added by appian automatically when you create an expression and saves it.....
