# Force Attach Scheme Reference with every Purchase having Schemes **YouTube:** [How to Enforce Scheme Reference for Purchases with Applicable Schemes?](https://www.youtube.com/watch?v=KIc0Oc7boh4) ## How to Enforce Scheme Reference for Purchases with Applicable Schemes? This tutorial explains how to ensure that a scheme reference is mandatorily attached to every purchase entry involving items with defined schemes. *** ### **Enable the Setting in Global Settings:** * Launch **Logic Admin**. * Navigate to **Global Settings**. * Go to the **Purchase Settings** section. * Locate and enable the option Labeled: **"Force Attach Scheme Reference with every Purchase having Schemes"**.

Let’s keep this feature enabled to observe its impact on purchase transactions.

* Click **Save** to apply the changes. * **Restart the software** to activate the new setting. *** ### **Implement a Purchase Entry with a Scheme-Associated Item** * Begin a new purchase entry involving an item linked to a predefined scheme. * If a scheme reference is not provided, the software will: * **Restrict the transaction.** * Display an **error message** indicating that a scheme reference is required.

As illustrated in the picture, an error message appears on the purchase screen:

*** ### **Add a Scheme Reference** * In the **Scheme Reference** column, press the **Spacebar**. * Select the appropriate scheme associated with the item from the list.

As illustrated, select the appropriate scheme from the list in the Scheme Reference column to proceed.

*** ### **Enable Scheme Reference Column (If Not Visible)** * If the **Scheme Reference** column is not visible: * Open the **Setup Column Attributes** option. * Enable the column manually from the available attributes.

As shown in the picture, select the column from Setup Column Attributes in the same way.

*** ### **Note on Scheme Setup** * Schemes are defined in the **Setup Schemes** window.

As shown in the picture, you need to create the scheme from here.

* Items linked to a defined scheme will automatically be flagged during purchase entry for reference selection. --- # Agent Instructions: 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.
