[Paul is creating this discussion from an email question] When ingesting connections between two objects, each object has a URI Lookup set to "create if missing" but some duplicates seem to be created. |
Beta Was this translation helpful? Give feedback.

We have discovered one circumstance in which "create if missing" does not always work. We've made some improvements but this will likely require a warning message or better documentation. In the mean time... "Create if missing" may create duplicates if the same item is supposed to be looked up and created by different columns in the same ingestion. This seems to happen most frequently when ingesting a list of relationships between two objects of the same class, where both objects (the subject and the object of the relationship) can be created if missing. The best workaround is a two step ingestion. First ingest all your objects with "Create if missing". Then ingest all your relationships using "Error if missing". |
