Calculated metric divides by a column that can contain zero values. Missing NULLIF() guard in ratio calculations. Data quality issue — denominator field unexpectedly contains zeros after a pipeline transformation

Step 1: Locate the division expression in the failing query.. Step 2: Wrap the denominator with NULLIF: `NULLIF(denominator, 0)` to return NULL instead of error.. Step 3: Add a data quality check upstream to flag zero values in denominator columns.. Step 4: Consider using CASE WHEN to provide a default value for zero denominators.
