Hi,

Junction Object is a custom object with two master-detail relationships. Using a custom junction object, you can model a “many-to-many” relationship between two objects. For example, you create a custom object called “Bug” that relates to the standard case object such that a bug could be related to multiple cases and a case could also be…[Read more]

Hi,

If the parent objects don’t have Roll up Summary fields for the child object then we can delete.
To delete a child object it should not be referred in Apex Classes and Apex Triggers.
Later if we undelete the object, Master detail fields on the junction objects will be converted to look up Fields.
Note:
If we delete only Master – Detail Rel…[Read more]

Hi,

Junction objects are used to create many to many relationships between objects. If you take the Recruiting application example, you can see that a Position can be linked to many Candidates, and a Candidate can apply for different Positions. To create this data model you need a third object “Job Application” that links the 2.

So you’d creat…[Read more]

Record level access is determined by the parent, Mandatory on child for reference of parent, cascade delete (if you delete the parent, it can cascade delete the child).

Hi,

Yes, we can convert Look-Up relationship to Master-Details Relationship but we can do  this conversion only if all the fields have valid look-Up fields values only.

Thanks

Hi,

You need to create a lookup field then fill this field with some parent value, then convert its type to master detail.

Hope this helps.

Hi,

You cannot create a new Master-Detail relationship on an existing custom object if records already exist. You must first create a Lookup relationship, populate the lookup field with data in all records, and then change the relationship type to Master-Detail.

Hi,

Creating Many to Many relationship in salesforce is little tricky. You cannot create this type of relationship directly. Follow below steps to create this type of relationship.
Create both objects which should be interlinked.

Hi,

When modelling a many-to-many relationship, you use a junction object to connect the two objects you want to relate to each other.

Creating the many-to-many relationship consists of:

Creating the junction object.
Creating the two master-detail relationships.
Customizing the related lists on the page layouts of the two master…[Read more]
