I'm trying to track history of Account Description field.
Related list just shows it has changed, but seems no value changes being tracked. Tried to query using SOQL, but it doesn't give any value changes.
Are we supposed to have our own approach to track long text fields? (e.g. have custom object and append records upon saving usign trigger). What is a recommended approach to do this? or anything I'm missing on this.
Appreciate any thoughts. Cheers!
The "Track Changes" fields (basically, anything that's a LTA) is a limitation of the platform; it can only track changes for fields of 255 characters or less. In the UI, the changes would be listed as "Field was changed." rather than having specific from/to values. If you want to track the full values, you would indeed need a trigger/process builder to track the full values. Note that this is going to be relative cost-ineffective, as each custom object record needs 2KB of storage.
