Salesforce Master Detail Relationship
We can't create a Master-detail relationship on existing records. To do that, we have to create a lookup relationship for that record and then convert it into master detail.
To convert a lookup relationship to a master detail the existing record should consist of valid lookup field values. You can build many to many relationships using two master detail relationships in an object, and it is called as Junction object.
Standard objects can't be on a detail side of a master detail relationship. Access to detail is determined by the access given for master. Only up to two master detail relationships are allowed for an object. You can have only Upto three levels of custom detail levels. We can't create a Master-detail relationship when the custom object already contains data.
