Interrupt processing when a condition is met. Reaching this step stops the current run by raising an error with a message you choose; it does not change the entity. It is most useful inside Apply transformer conditionally, so you can deliberately fail a run when the data is invalid, for example when a required field is missing or a value is not allowed. The message you write is recorded so you can see why the run was stopped.

Sample data

This feature does not change the entity; reaching it stops the run. With the configuration below, any entity that reaches this step halts processing and records a message such as Order 1001 has no customer email, so no further steps run for that entity.
