When we change owner of a record (Ex opportunity) on Salesforce, there is a message at the top of the page saying :
This screen allows you to transfer an opportunity from one user to another. When you transfer ownership of an opportunity, the new user will own:
- all notes that were recorded for this opportunity owned by XXXXX
- all activities (tasks and events) that were recorded for this opportunity owned by XXXXX
Hence, all the activities belonging to the previous owner will be now owned by the new owner.
However, if we change the owner of the opportunity by Data Loader, the activities owner do not change.
Is there a way to change the activities owner while updating the owner of the opportunities by data loader?
Or do we need to update the activities owner separately by dataloader?
OwnerId
to the id stored on said field. Have you tried that?
