# Material Timeline and Audit Trail

## 📜 **Material Timeline and Audit Trail in Ontraccr**  
 

## **Overview**

Every material and assembly in Ontraccr comes with a built-in **audit trail** called the **Timeline**. This feature provides a transparent history of edits, quantity updates, and workflow-triggered changes — so your team always knows *what happened*, *when*, and *why*.

This article shows how to access the timeline and what kinds of actions are tracked.

## **🔍 How to View a Material’s Timeline**

1.  From the **Materials Page**, click on any material or assembly.
2.  This opens the **non-edit view** of the item.
3.  At the top, switch to the **“Timeline”** tab.

## **🧾 What the Timeline Shows**

The timeline includes:

-   **Creation details** (date/time and who created it)
-   **Edits** to:
    -   Name, description, pricing, cost codes, etc.
    -   Inventory quantity or thresholds
-   **Workflow activity**:
    -   Updates from forms or processes (e.g., daily logs, purchase orders)

📌 *Use Case:* See if inventory dropped because a team member submitted a daily log that debited wire.

* * *

## **🔄 Integration with Workflows**

If your forms or boards use the **“Update Material”** step, any automatic changes will also appear in the timeline.

### Example:

A daily log form deducts `5` units of wire.

Timeline entry appears:

*“Material debited by 5 units via Daily Log (submitted by John Doe on May 10)”*

📌 *This creates a full audit trail*, even for automated system actions.

* * *

## ✅ **Benefits**

-   **Transparency**: Know when stock levels changed or fields were edited.
-   **Accountability**: See which user made each change.
-   **Troubleshooting**: Quickly track down inventory issues or data entry errors.

## 🧠 **Real Use Cases**

-   Confirm whether a part was added manually or via upload
-   Audit labor pricing changes during a rate update
-   Validate inventory deductions tied to a work order
