# Configure and Use Defect Causes on K2App
## Configure and use defect causes in K2 App to optimize tracking of parts in production. Follow this step-by-step guide to improve your traceability.
This procedure guides you through the steps to **configure and use defect causes on K2App** for your machines. The goal is to enable you to easily track and understand the reasons for part rejections in production, thereby improving traceability and optimizing your processes.
Prerequisites
1. A valid user account on **K2 App** with the necessary permissions.
2. A machine already configured in the application.
### Step 1: Create Defect Causes
1. From the left menu, in the **"Configuration"** dropdown button, choose the **"Machines"** section.
2. Select your desired machine (e.g., **Bending Machine**).
3. Choose the **"Reject Causes"** tab.
4. To create a new cause, click on the **"+"** icon.

### Step 2: Create a New Rejected Part Rule from scratch
1. From the left menu, in the **"Configuration"** dropdown button, choose the **"Rule Engine"** section.
2. Click on the **"Create a Rule"** button.
3. Assign a relevant name to your action (e.g., **Bending Machine – Add a Rejection**).
4. If desired, customize a **Label** for this action.
1. In the pop-up windows **"Tags Modification"**, fill-in your machine name (e.g., **Bending Machine**) then select. Click on **"Submit"**.
5. In the **"When"** section, select **"Button"** as the trigger.
6. In the **"Then"** section, click on **"Select an Action"** on the top-right.

1. **Action Name:** Assign a relevant name to your action (e.g., **Bending Machine – Add a Rejection**).
2. **Machine:** Choose the machine concerned by the rejection (e.g., **Bending Machine**).
3. **Event Name:** Define a name for the event (e.g., **bendingMachineScrap**).
4. **Number of Parts:** Enter **1** to record a single part at a time.
5. **Event Type:** Choose **"Scrap"**.
6. Activate the **"Defect Cause"** toggle to assign automatically a selected cause the rejection.
7. If desired, customize a **Tag** for this action.
8. Click on **"Add"**.

4. **Rule:** Select the rule you just created (e.g., **Bending Machine - Add a Rejection**).
5. **Color:** Choose a color for the button tile.
6. Click on **"Submit"** to save the tile.
5. Adjust the placement of the button tile on your dashboard if necessary.
### Step 4: Activate the Defect Cause Selection Window

*Tip :* You may access to the declared defects via the timeline tile and its comic-bubble icon. Une fois sélectionné, simplement cliquer sur l'onglet Rejets pour accéder à la vue détaillée des rejets déclarés dans le quart.
*Warning : when you configure defect causes*, ensure to communicate this change to your Customer Success rep by submitting a Support Request. We will make sure to activate the Quality module in your reports.
### Best Practices for Managing Rejection Causes
- **Clarity:** Use clear and precise names for your rules, actions, and rejection causes to facilitate management and data interpretation.
- **Consistency:** Maintain consistency in the use of colors and icons for quick identification.
- **Training:** Ensure that operators understand the importance and procedure for recording rejection causes.
- **Updating:** Regularly update your rejection causes based on the evolution of your processes.
### Conclusion
You have now configured a complete process for tracking rejections on **K2 App**. This configuration is essential for improving traceability and analyzing rejected parts in production, thereby contributing to continuous improvement and optimization of your operations.
