Anyone know if you can trigger a workflow on a summary saved search and if it triggers on the summary results or the detail results or not at all?

Yes it will run on summary results and it will only process the records in the summary results not the details

Thanks for the reply. can you give an example of this? For instance I'm using a transaction search and grouping by customers. I only want to do an action for the customer.

It runs on every instance of the record type in the search. So if you want to effect Customer, then you need to create a Customer based search.

Well the only issue is i'm referencing either line level system note field or information not available on the customer record. so it's 2 degrees of freedom, when saved searches only give you 1.

What is the timing of this? Does the WF need to just trigger nightly or monthly? If so you could probably do it in 2 workflows

daily.. So yeah you could set a field with the flow then have the other flow look for that and fire off the action. but was hoping to contain this in a single flow.
