Unable to deploy Account object to a sandbox

Question

I am getting the following error when deploying from one of the sandbox.

All Component Failures:
1. objects/Contact.object -- Error: Read is not a valid sharing model for Contact when Account sharing model is Private
2. objects/Case.object -- Error: ReadWriteTransfer is not a valid sharing model for Case when Account sharing model is Private
3. objects/Opportunity.object -- Error: Read is not a valid sharing model for Opportunity when Account sharing model is Private

*********** DEPLOYMENT FAILED ***********

Answer 1

These objects have master-detail relations. As such they (the "detail" objects) inherit their sharing from the master. What you've tried to do is say that Accounts are private, but Contacts are Read(able). This is not permitted under Salesforce sharing rules:

You don't say how you're deploying, so I'll assume Eclipse or ant.

The simplest way to get deployable metadata is to make the changes in your sandbox and pull all the metadata. Don't try and hand edit files.

In this case you'll set Account model to "Read" and Contact sharing model will change accordingly. THen when you pull the metadata for both Account.object and Contact.object they'll be in agreement. Same applies for your other errors.
