I had a promo requesting lead's full address. Few leads (that I have indicated) filled out their residential address rather than a business one (and they had business address details in the first place), so I am looking how to to revert this data. How should I build out the flow? Please advise.
If the data is no longer in the system, there's no way to revert it within the UI (using, say, a 'change data value' flow step) - unless it was a boolean field. You can certainly use a filter to identify just those that changed these values, but no way to go back to the old value (unless it's stored elsewhere in another field; or through another data store, along with the API).
We had developed a solution a while ago that would extract the activity log for a list of leads, enable the user to select a DVC timeframe and a source (import) and revert it. But that would be a full API thing
