Public search query: Power BI incremental refresh failed: data source error duplicate key viola
Problem outcome: unknown
Fetch the existing object first and update it in place, or merge the duplicates and keep the record with the fuller history, instead of creating a second one. Use when you see this exact failure in Feast and the affected record or object can be named. Not for a different Feast error with another message, or for genera…
Find the duplicated key combination before touching the test: run the test query grouped by the key columns, inspect the duplicate groups, and fix the join or fan-out that creates them, or correct the key if the declared combination is not actually unique in the business data. Use when a dbt model whose declared uniqu…

Public search query: uniqueness check passes in warehouse but fails in lakehouse copy of same table error
Problem outcome: unknown
Incremental models duplicate keys when the unique_key does not match the real grain or when late data bypasses the merge: inspect the duplicates the run created, confirm the unique_key columns in the model configuration, and rebuild the affected window with a correct merge. Use when an incremental dbt model producing …

Public search query: how to fix duplicate primary key failure error on incremental model run
Problem outcome: unknown
Duplicate keys on merge mean the source side of the merge has more than one row per key or the target already does: check both sides for duplicates on the merge key before rerunning, deduplicate the source on the latest record, and make the merge idempotent so a retry cannot insert a second copy. Use when a warehouse …

Duplicate business keys in a dimension table mean the dimension's grain broke: identify the duplicated keys, check whether a source started sending multiple active records per key or a slowly changing dimension lost its current-row filter, and rebuild the dimension at the correct grain. Use when a dimension table with…

Public search query: uniqueness test failure error: duplicate business keys found in dim table
Problem outcome: unknown
Snowflake does not enforce primary keys, so duplicate values surface through merges and checks rather than constraint errors: find the duplicate keys, determine whether the source or a retried load created them, and deduplicate with a qualify on the load timestamp, then add a uniqueness check to the load so the next d…

Fetch the existing object first and update it in place, or merge the duplicates and keep the record with the fuller history, instead of creating a second one.

Reconcile from key listings, not full tables: have the agent pull the key sets and hashes per warehouse, diff the keys in set operations, and only fetch full rows for the mismatched keys. Use when an agent failing while reconciling duplicate keys across warehouses. Not for reconciling within one warehouse, where set o…

Query the source grouped by the key to find the duplicated keys, fix the upstream join or dedupe rule that produced the second row, and only then re-run the refresh. Use when you see this exact failure in Power BI and the affected record or object can be named. Not for a different Power BI error with another message, …
