I'm using a flow to set a field to a certain value (01, 02, 03) depending on the value of another field on the same record. I initially wanted to do it with process builder but because of the mapping it seems I would need three 'criteria nodes' or a formula field. Furthermore, it seems Salesforce is recommending using flows instead of process builder for before update actions as it is faster.
The problem with Flows is that I found a way to trigger it when the record is new or updated but not when the specific field is changed so it triggers every time the whole record is updated even when the field stay the same.
On Process Builder, you can use isChanged and then call the flow with specific record but that kinds of defeat the point of using flows for before Update.
So is there a possibility to do the same thing directly in flow ?
Thank you for the help !
