Trying to change the existing relation between A(Parent) and B(Child) from Look up to Master- Detail. Deploying "B__c.A__c" using ANT.
- Ran a query on B and made sure all B__c.A__c is populated (As per the documentation, if all look up fields are populated, we can convert relation from lookup to master-detail)
During deployment, I am getting error "cannot add master-detail relationship due to existing data rows"
Any idea on resolving this.
Thanks
