delete converted lead

Hi Sheila McPhail,

Since you can manually delete a Lead record from the user interface, I interpret the implication of your question as about what impact the deletion of a converted Lead with a Note history will have upon that Note history.

If the Notes are related to the Lead, not the Contact, then when the Lead is deleted the Notes will be orphaned, as is the case with other relationships when a parent record is deleted.3

I hope this helps!

While converting your lead to contact or account , eventually the whole history of your choice should be  "move" or "do nothing"  to new record which sugar already providing you from admin -> system settings->

Lead Conversion Options:

now you need to create an after save hook which will see lead new status to "converted" , if found , you need to use mark_deleted() function.

Can I ask why you feel the need to delete a converted Lead?

That's a very common requirement as Lead is already moved to next level, that means it does not needs to be sitting there as a lead ie person/company is already under either contact or account.
