I want to retain the Account Team whenever the OwnerId
changes, as per this post.
After we make the checkbox named "Keep Account Team" to be true, we can change the ownership of accounts while locking all the associated account teams.
But I am not able to find any field in the org even though I have Unlimited Edition.
Also, here is a post for retaining the Account Team via SOQL.
Please suggest as the second methodology seems to be complex to maintain them in the collection and remapping them after the ownership changes. While First one (I have never used) seems like can be done via configuration only.
