# Amend agreed production dates

> Change the agreed start, completion and ex-factory dates of a production order, record why, and optionally tell the supplier.

Source: https://docs.vestislabs.com/production/production-order-amend-agreed-dates/

The **agreed dates** of a production order are the production start, production completion and ex-factory dates you and the supplier planned. When the plan changes, amend them and record the reason. The original dates stay in the amendment history.

**Where to find it:** Production → Order Management → three-dot menu → View/Edit → Amend agreed dates
**Requires:** permission `UPDATE_BRAND_PRODUCTION`

## Before you start

- You need the **Update** production permission.
- The **Amend agreed dates** button is not shown to supplier users. They can respond to confirmation requests, but never change the agreed dates.
- To record when something really happened, use [Update actual production dates](https://docs.vestislabs.com/production/production-order-update-actual-dates/) instead.

## Amend the dates

1. **Open the order**
   On the **Production Orders** page, select the three-dot action button on the order's row and click **View/Edit**.

2. **Click "Amend agreed dates"**
   Click **Amend agreed dates** at the bottom of the order dialog. The **Amend agreed production dates** dialog opens: "You are changing the agreed production dates for this PO. The original agreed dates remain in the amendment history."

3. **Set the new dates**
   Choose the **New agreed start**, **New agreed completion** and **New agreed ex-factory** dates. The fields start with the current agreed dates, so change only the dates that move.

4. **Enter the reason**
   Type why the dates are changing in **Reason for amendment**. This field is required: without it the form shows "Reason is required".

5. **Add a note for the supplier (optional)**

6. **Choose whether to notify the supplier**
   Check **Notify supplier of amendment** to tell the supplier about the change.

7. **Click "Save amendment"**
   Click **Save amendment**. The dialog closes when the amendment is saved.

   ![The Save amendment button at the bottom right of the completed form](https://docs.vestislabs.com/assets/production/assets/production-order-amend-agreed-dates/66-save-amendment.webp)

The **Agreed Dates** card on the **Overview** tab now shows the new dates.

## Rules for the dates

- The completion date cannot be earlier than the start date: "Completion cannot be earlier than start".
- The ex-factory date cannot be earlier than the completion date: "Ex-factory cannot be earlier than completion".
- If the platform rejects a date, the message appears under the date field it concerns.

## Amendment history

When the order has been amended before, the dialog lists the earlier amendments under **Amendment history**, newest first. Each line shows which date changed (**Start**, **Completion** or **Ex-Factory**), the old date, the new date and the reason.

## Closing without saving

If you changed something and close the dialog, the platform asks **Discard unsaved changes?** Click **Keep editing** to go back or **Discard changes** to close it.
