How many master detail relationships and lookup relationships can we create on an object? (For Latest Salesforce Release)

1 Answer 1


You can create up to 2 Master-Detail Fields on a single Object and with Winter '16, the default limit on roll-up summary fields per object has been increased from 10 to 25.

  • @SourabhCoolkarni As of and if you read the release notes, you'll find nothing has changed in relation to this. Limits are the same.
