Preventing Merged Leads from overwriting source fields

[Anonymous]

It appears that source fields, which are meant to indicate origin, such as lead source, original referrer, etc. are overwritten with the newest lead when leads are merged.

How do we stop this from happening?

Thanks

please create this as an idea request. As far as I know, this is generic behavior that applies to all fields, not just the source fields

Thanks

This would explain why I have leads with activities typically associated with a known lead (e.g. fills out form, Sent Email, etc.) that have dates before the Created date.  I've noticed a similar phenomenon when converting / merging a Lead into a newer Contact record in SFDC.  To preserve the original creation date, I created a "Lead Created Date" custom field, so I can detect when the Created date is incorrect due to undesired behavior during merges and converts.

Jack, please create an Idea for this as its pretty important.
