How to define Expression in action condition definition?
I have a question about expression definition for action.
I want to take yesterday's date from system. But there is no available Container Element.
So i want to use system field %DATLO%(system currect date = today's date) to decrease one day. For example: %DATLO% - 1.
But it is error, i don't know how to express.
If need to creat a new element, how to evaluate the new element?
Thank you very much.
