Salesforce: Check if Record Has Been Manually Edited
We recently had a requirement in Salesforce that was a little unique. An ongoing automated process would update the associated Contact to a record, however they didn’t want the automated process to do the update if the field had been updated by a human. Makes sense – if someone takes the time to make a manual association of a Contact to a record, then it’s probably better information than the automatic matching algorithm.
As far as I can tell it’s impossible at runtime to know if the edit is due to a UI edit or is coming from code, so that’s out.
Here’s how we made it happen. The idea is to have a “last updated by code” checkbox that will be set by a workflow. But in order for it to know if it’s been updated by code, you need a 2nd checkbox that is only updated in Apex.
First, make two checkboxes on your record:
Set the latter to true by default when a new record is created.
When your code updates the record, set Contact_Change_Trailing_Lock__c = true.
Then, make two workflows.
-> Field Update – Contact_Last_Changed_By_Code__c = false
–> Field Update: Contact_Last_Changed_By_Code__c = true
–> Field Update: Contact_Change_Trailing_Lock__c = false
This results in you being able to use the Contact_Last_Changed_By_Code__c checkbox downstream in your logic to know not to overwrite the manual edit.
