# Decision logs

The decision log records all decisions that ultimately led to the final assignment of an order to a facility. It helps explain why an order was routed to a specific facility. Crucial to this decision is how the routing strategy was configured, meaning which fences and ratings were activated. The decision log is connected to the [routing plan](/documentation/by-pillar/advanced-order-routing.md#routing-plan).

The routing plan contains an array with references to the URL where the decision logs for this routing plan can be retrieved. Each decision log contains information on how a facility performed in the routing process.

* The array `facility` contains the decisions made for every facility.
* In the `statistics` object there are statistics for each fence and rating, e.g., how many facilities were passed or were rejected for a certain fence or which was the maximum or minimum score a facility received in the routing process.
* The `result` quickly summarizes which was the best rated facility and which was the best facility available.

**Example**

The example decision log below shows how our Nerd Herd Clothing Warehouse facility was selected. The facility passed all fences and it was also rated the best facility in the ratings. The other facilities didn't have enough stock. The details show that 1 item was expected, while the facilities had no items available.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fulfillmenttools.com/documentation/by-pillar/advanced-order-routing/decision-logs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
