Opportunity Splits aren't transferred during an owner change for closed Opportunities
|Knowledge Article Number||000220186|
|Description||When changing Ownership of closed Opportunity, the Team is retained (even with box unchecked) and when you attempt to remove the Split for the previous Owner, users get the following message, "Can't remove a team member assigned to a split from an opportunity."|
|Resolution||This is by design for Closed Opportunities. To remove the previous splits, use the API.
