Is it possible to populate a field in every record that shows up in a portal with data from a different field. I don't know that I need to constrain to just the records showing in a portal but at least to just the associated records of the parent.

 

Like a portal showing tasks in a todo list for a single user and you want to set a field on each record in the portal to complete.

 

Not completely necessary at this point but I would also like to be able to use this same technique if I am viewing a portal that show a limited criteria say tasks created before 2 weeks ago. In this example I would want the functionality to only change the records being displayed in the portal. 

 

I am guessing I should try to accomplish the later so I am not stuck reworking the problem when I come to it later.

 

Is this something anyone else has done or seen?

I'd be careful here. One click changes to multiple records can be dangerous as they are not often reversible. But, yes, it can be done. Have you viewed Todd Geist's "understanding commit" video? That clearly shows how to manipulate (and reverse) edits to child records.

Thanks, I'll have a look. I understand it is potentially dangerous. Thanks for the warning!
