What is the 'Preserve Order Expression' in Case Transform used for?

Hi,

Preserve Order Expression specifies to process expressions in the order presented. When this option is not checked, Data Services process the expressions in a less CPU intensive order, which enhances performance but When this option is not checked, the expression reordering can change results. There is no way to guarantee which expression evaluates to True first.

This option is available only when you enable Row can be TRUE for one case only.

Please Check this option if expression order is important to you.

Thanks,

Prathy

Thanks for the answer. If you could explain the expression reordering part little bit?
