Using Function inside Function

Sometimes when you write rules, it so happens that the condition, and what to do next are all calculated terms.  Let's Consider this example.

Now what will happen if F2 Changes.  This IF rule will be re-evaluated, eventhough the…

Search-Criteria in RCall & ChildCall

Whenever you want to do certain things in another model other than the one you are currently in, you would be using RCall and ChildCall to achieve it.  RCall and ChildCall have a property called Search-Criteria to say on which records to perform the calling action.  


Previously you could write your search-criteria directly in the property field.  From now on you will have to use the CRITERIA() function to provide the search-criteria for these two action…
