Is Replica Of Anomaly Reporting
Deprecated: use Data Diff instead
The Is Replica Of rule is no longer maintained. Data Diff replaces it with the same row-by-row comparison plus change-type filtering. This page is kept as a reference for checks that already exist; new checks should use Data Diff.
How the Is Replica Of check reports a divergence, and where to find the differing rows.
Anomaly Messages
Is Replica Of emits a Shape Anomaly only, one per failed comparison. The message names the compared fields, as a comma-separated list, and states that the referred fields do not replicate the targeted ones:
When a filter is set, the message ends with [filter: <expression>]. There is no per-row variant: the divergence belongs to the dataset, not to a single row.
What the Numbers Mean
- Differing rows: the rows the comparison could not match, available in the anomaly's source records.
- Row Identifiers: when configured, they are what pairs a target row with its reference row and make the per-row detail readable.
Source Records Behavior
With Row Identifiers configured, the per-row detail is rendered in the Comparison Source Records view, showing each differing row side by side. See Comparison Source Records.
Custom Anomaly Description
Custom Anomaly Description does not apply to this rule. The option replaces the message on Record Anomalies, and Is Replica Of emits a Shape Anomaly only.
