Understanding the 'Dag is Cyclical' Error in Mapping Outputs

·Oct 17, 2025 08:30 AM·

Hi I was wondering what the ‘Dag is cyclical’ error means when trying to map and output to an existing column

The "DAG is cyclical" error occurs when you create a circular dependency between columns—meaning a column depends on itself, either directly or through other columns.
This commonly happens when:
Mapping output to an existing column that the enrichment itself references
Creating infinite update loops where changes trigger continuous updates
To fix this:
1.
Map the output to a new column instead of an existing one
2.
Check your column dependencies in Run Settings to identify the loop
3.
Reconfigure your Write to Other Table integrations if using cross-table references [1]
Avoid mapping enrichments back to columns they depend on to prevent circular references.

Where do I check the ‘run settings’ of the column

To access Run Settings for a column:
1.
Click the column name → select Edit column [1]
2.
Navigate to the Run Settings tab
This section shows dependencies, conditions, and auto-update settings for that column.
