# Postpone a planned order - Impact workspace

Use **Postpone** to change the requirement date of a planned order. For example, postpone the order when supply should align with the ECO effective date or the availability of the **To version**.

## Steps

1. Go to **Product information management > Engineering change management > Engineering change orders**.
2. Open a released ECO you want to review.
3. On the Action Pane, in the **Business impact** group, select **Open impact workspace**.

The workspace opens for the selected ECO.

> [!NOTE]
> Note
> 
> If the ECO has no lines yet, the button is unavailable. Add at least one affected product first.
4. In the **Planned orders** section, locate the affected planned order.
5. Select **Postpone**.

The **Postpone** pane opens on the right.
6. Review the planned order number and item number.
7. In the **Delivery date to replace** field, select the new requirement date.
8. Review any warnings about affected demand or supply coverage.
9. Select **Postpone** to change the date.

To close the pane without changing the date, select **Cancel**.

After the date is changed:

- The **Requirement date** shows the new date.
- The **Action status** changes to **Postponed**.
- An entry is added to the **Change log**. For more information, see [Track actions in the change log](/manufacturing/docs/track-actions-in-the-change-log-impact-workspace).

## **Review the supply impact**

Postponing an order can leave demand without supply during the period between the original and new requirement dates.

If the pane identifies affected sales orders or other demand, review the warning before continuing. Arrange alternative supply if the date change would cause a shortage or delivery delay.
