I have set of 5 custom object and one parent object for them. suppose A is parent record and its child record of different object are B,C,D,E and F. What i need is owner of record B can read/edit B but should have read only permission for C,D,E and F. Similarly owner of C should have read/edit permission on C and read permission for B,D,E and F.
How to go for this scenario. Ready to create extra field if required to store owner or something else on parent or child objects.
