You can use enumerations, should read something like:
$currentObject/yourenumeration = ModuleEnumExistsin.NameOfEnum.Value
Or
you can choose “based on attribute value” then select the enum value, then change it to “based on expression” and it will write the expression for you
yes, you can reference enumeration values by specifying the fully qualified enumeration value. See an example below:
If you want some help in finding the enumeration while building your expression, use CTRL – Space Bar to get a context sensitive list of options. You can narrow down this list by typing part of the enumeration name.
