Hi
Yes, It will autocommit the other one.It is best to commit both objects. Autocommit objects are not advisable. Please refer this below documentation for both more clarity on commit & autocommit objects.
Hi, the autocommit functionality as per the documentation works only when you create the association.
Meaning, if you have Object A and Object B, when you create Object and associate it with Object A then auto commit works.
When you want to edit the object B or Object A, then autocommit does not have any effect. You have to commit it separately.
So, it is wise to handle the commit yourself.
It's best to commit both
Thank you!
