Rule-Obj-When

When rule is used to evaluate a logical statement involving comparisons among values of properties.

Conditions Tab:

Value of the properties can be evaluated against any of the comparison operators, like
=
>
<
>=
<=
!=

Advanced Tab:

This functions similar to the Conditions tab with below comparison expressions, like
Equal
Greater
Less
Not Equal
Greater/Equal
Less/Equal

Only difference between specifying conditions in the above 2 tabs is that,

With conditions tab, properties can be evaluated against only similar logical conditions.

(ex: we A and B and C, we cannot have A and B or C )

Whereas with Advanced Tab, any kind of logical expression can be implemented.
