With a multi-source CMDB , IRE (Identification & Reconciliation Engine) is key to maintain the data integrity .
IRE comes with many features & capabilities to help in the identification ( What makes the record unique) , and reconciliation (which data source takes precedence ) of CMDB data .
Let’s have a look on Dynamic Reconciliation rules.
You cannot use Dynamic Reconciliation If the following features are not activated in your instance:
What needs to be enabled in order to use the Dynamic Reconciliation Capability ?
You need to activate the following features :

What Do I need to know about Reconciliation Rules ?
- Dynamic reconciliation rules were introduced in the San Diego release
- The Data source may not be the same each time
- CMDB 360/Multisource must be enabled
- If the same CMDB data Record / CI attribute has Static & Dynamic Reconcilaition Rules defined , the dynamic reconciliation rule has precedence
- CMDB 360 retains history about values to populate CI attributes
- IRE has a mechanism to choose the most appropriate value
