One of the most advantage using Master-Detail relationship compare to
Lookup relationship is Roll-Up Summary. In Master-Detail relationship,
we can create roll-up summary field in master record to summarize /
count data from child records.
Few items to notice when create roll-up summary field:
Parent record is locked
If you implement approval process with lock record, user will not able to create new child record if Sharing Setting in Master-Detail option is Read/Write.
Solution: change the sharing setting to Read Only.
Validation rule on parent record
If user not able to edit parent record and you have roll-up summary in parent record, user will not able to create or edit child record.
Solution: remove roll-up summary fields.
Can I change field type from Master-Detail to Lookup relationship?
Yes, make sure there is no roll-up summary fields in parent record, also in Deleted Fields (erase from Deleted Fields).
Can I change field type from Lookup to Master-Detail relationship?
Yes, all parent record should be not blank.
