Data Change Request (DCR) Inconsistency updates.

Problem : 

When adding an additional nested attribute value through a Data Change Request (DCR), the existing attribute value is being overwritten instead of appending a new entry.

Cause : 

This issue arises because of an incorrect configuration within the tenant's physical configuration related to the Data Change Request. The misconfiguration in the tenant is causing the system to behave unexpectedly. 

Solution : 

To address this issue, kindly contact Reltio Support and update the following property in the tenant physical configuration: 

useNewDCRs : true
connectRelationsToDefaultCrosswalk : true
enableReferencePartialOverride : false
