The Creation Index stores Domain Object records created for linking in Link Mapping.

• A. True
• B. False
• C. Only for testing
• D. It stores output data

Answer: (A)

In OmniStudio, the Creation Index serves as a temporary store for Domain Object records that are created during a flow so they can be referenced and linked in Link Mapping. This allows newly created records to be connected to each other or to existing records within the same transaction without needing to fetch IDs later, ensuring the intended relationships can be built smoothly. It’s not about testing or merely producing output data; its purpose is specifically to hold those created DO records for linking in mappings.
