Field Update
A field is being updated with a value - you don't know where it's coming from. How to track it down:
- Set history tracking on that field if you can (if you don't have 20 fields already)
- Alternatively set Feed Tracking for that field (probably turn it off after you find it).
- Does it have a default value
- If it's a picklist,is that value checked as default.
- Search for the field in the Setup Search
- https://instance.salesforce.com/ui/setup/SetupSearchResultsPage?setupSearch=Field%20Name
- Look in the Field Updates list of Workflows to see if any active workflow is updating the field.
The next ones are a bit harder.
- Is a Process Builder updating the field - good luck with finding which process is updating the field - you will have to look through each and every process.
- Is a Flow updating the field - again you will have to look through each and every Flow - but look for the Record Update and Record Create panels.
- Finally it may be a trigger. Use tricks like MavensMate and Git for Non Developers to export the Salesforce configuration to a text file so you can search through the files for the field name (search on the API name).
