I'm designing a flow to roll up values to a parent record, and although I've reviewed the documentation here on bulkification, there is a piece that I haven't quite figured out.
The flow will run upon update of a child object (say, Opportunity), and update a value on its parent (say, Account). I understand that, once I get to the Update Records element, the interviews will wait and execute a single update
call. What I don't clearly understand is, if multiple Opportunities trigger the flow in a mass update, and some relate to the same parent Account, will the list be de-duplicated? Or should I expect to encounter a duplicate IDs in list
error?
If the latter, I would assume this is a use case that has to be solved via Apex instead, and there is not a way to de-duplicate the Accounts across flow interviews. Is this a known flow limitation?
