Hello Sir, Great Explanation !
I got a question such as : If we have a MD between two objects and we have 1 Master and 100 Child records. If we deleted the Master record total how may records will be deleted . And where will be the deleted records go to after deletion is completed.
Kindly share the answer ! Thanks in advance. @Premium Learnings

[@tchassakamga]

From my understanding, when you delete the Master Record, all Child records would be deleted as well (100). They'd go to the recycle bin. And if you were to restore the Master Record, the child records will be restored as well.
