# End iteration

## Description

The **End Iteration** activity marks the termination point of a repeated loop created using the **Start Iteration** activity.  
It acts as the final checkpoint where the workflow gathers and optionally merges the data produced during each iteration cycle.

This is especially useful in scenarios where:

- Multiple data batches are processed in a loop.
- The results from each loop need to be collected for reporting, analysis, or downstream processing.

> **Use Case**:  
> After looping through a list of input files or records, use **End Iteration** to collect the final results in a single table and determine whether to stop the entire workflow on failure or specific conditions.

| Data | Combined or final iteration data |

## Configuration Fields

| Field                                   | Required | Description                                                                                                         |
| --------------------------------------- | -------- | ------------------------------------------------------------------------------------------------------------------- |
| **Merge data of all iterations**        | Optional | If enabled, the output from all iterations will be merged into a single dataset.                                    |
| **Terminate workflow on any iteration** | Optional | If enabled, the workflow will immediately stop if any iteration returns a failure or meets a termination condition. |

## Sample Input

_Not applicable_

## Sample Configuration

| Field                               | Value   |
| ----------------------------------- | ------- |
| Merge data of all iterations        | Enabled |
| Terminate workflow on any iteration | True    |

---

## Sample Output

Not applicable — Output depends on prior iteration logic. When enabled, expect a unified dataset containing combined results from all iterations.

> Use **Terminate Workflow on Any Iteration** to gracefully stop long-running loops if one of the iterations fails .
