Error 'field integrity exception' when you migrate sharing rules with change sets

Root Cause

This error occurs if the Organization-wide Defaults (OWD) grant different access levels between the source and target environments. For example, if the source org has Case OWD set to 'Private', the role definition includes Case access details. If the target org is set to 'Public Read/Write/Transfer', the role cannot accept those access details — resulting in the 'field integrity exception: unknown (Case access level below organization default)' error.

Resolution

To resolve this error, update the Sharing Settings for the affected object in the target organization to match the settings in the source organization.
