# 'MaterialSku is not specified in business unit' Error When Creating a PO and Attaching a Job

## Problem

When creating a PO and trying to attach a job to that PO, you may encounter the error message *MaterialSku is not specified in business unit*.

## Solution

1. In Pricebook, [create a Time and Material task](/roofing/docs/add-services-to-your-pricebook) and select the **Time and Materials Service** option.
2. When finished, click **Save**.
3. On the navigation bar, go to **Settings > Operations > Business Units**.
4. Locate the business unit and click **Edit**.
5. On the *Material SKU* field, assign the material SKU to the business unit.
6. When finished, click **Save**.

If you do not have the Time and Materials feature enabled, add the purchase order to the job without making it a *Time and material* service.
