# Writing to your ERP

> Turn draft Spherecast orders into real orders by syncing them to your ERP.

## What this page is for

Every order you create or accept in the supply plan starts as a **draft inside Spherecast** — a **Recommended / Draft** order that lives only in Spherecast and has not reached your system of record. This page shows how to make those orders real by pushing them to your **ERP**.

An **ERP (Enterprise Resource Planning system)** is your company's system of record — where real purchase, work, and transfer orders actually live once they are committed.

## How it works

The action is **Sync to ERP**, found on each order's detail page — whether it is a **Purchase Order**, a **Work Order**, or a **Transfer Order**.

A few rules apply:

* A **purchase order** needs nothing extra — you can sync it straight away.
* A **work order must be approved first**. If it is not approved, the sync is blocked and you see a message telling you to approve it before you can write it.

When you click **Sync to ERP**, Spherecast asks you to confirm — **"Are you sure you want to write to ERP?"** — then shows **"Writing…"** and finally **"Written to ERP successfully."**

You can also sync **recommended purchase orders directly from the recommendations view**, without opening each order's detail page first.

## Step by step: sync an order to your ERP

1. Open the order's detail page (Purchase Order, Work Order, or Transfer Order).
2. If it is a **work order**, approve it first — otherwise the next step is blocked.
3. Click **Sync to ERP**.
4. On the **"Are you sure you want to write to ERP?"** prompt, confirm.
5. Wait for **"Writing…"** to become **"Written to ERP successfully."**
6. The order now exists in your ERP.

## Example

You created a draft purchase order for 600 units of **CB-2010** from the supply grid. You open it, review the quantity and supplier, and click **Sync to ERP**. You confirm the prompt, the button reads **Writing…**, and a moment later **Written to ERP successfully**. Your buyer now sees the PO in the ERP.

For a manufactured item, you first **approve** the work order, then **Sync to ERP** the same way.

> **Note:** Syncing is the **point of no return**. Before you write to the ERP, an order is a draft you can freely change or delete. After you write it, the order exists in your ERP — treat it like any real order and make changes there.
