# Purchase order number not ending with -001 and so on, even though it was created within a project

## Problem

Sometimes, a PO number does not end with -001 or continue in sequence. This happens even when the PO is created within a project.

## Solution

### Purchase order number not ending with -001 and so on, even though it was created within a project

If a PO is only linked to the project and not a specific Job, it won't follow the -001 sequence. Here is how to associate the PO with a job.

1. In the main navigation bar, click **Purchasing** or **Inventory.**
2. In the left side menu, click on **Purchase Orders**
3. Locate the PO in the applicable tab: *Pending, Sent, Partially Received, Received, Canceled*
4. Click on the hyperlink in the *PO. No.* column to view the PO details
5. Click on the **Actions** dropdown and then select **Edit**
6. In the *Job #* field, select the appropriate job
7. Click **Save**
