# See Where a Function Exists Across Flows

You can now see exactly where a function participates across endpoints and topics, including when it was first and last invoked within each flow.

**Details**

* Added a new top-level Exists in Flows table on the Function page.
* The table lists all endpoints and topics where the function appears.
* Each row includes service, entry point, type, runs per day within the flow, distribution of total runs, first tracked invocation, and last tracked invocation.
* Functions that are the first invoked in a flow are marked with a Directly called from tag, including an explanatory tooltip.
* Supports free-text search by entry point name and applies to both endpoint and Kafka flows.

**Why It Matters**

This view makes it easier to understand how and when a function is used across different flows. It adds historical and structural context that helps teams trace behavior changes and investigate issues more effectively.

**How to Access**

Open any Function page in the Hud web app. The Exists in Flows table appears at the top of the page.
