# Add a Storage Unit to Loose Stock

> Learn how to assign a storage unit to loose stock using receipt reversal or the Add Stock feature with this configuration guide.

If you have stock in the system without a storage unit reference, there are two ways to assign one: reverting the original receipt, or using the Add Stock feature.

## Option 1: Revert the original receipt

Undo the original booking-in receipt, then add a storage unit to the specific stock line when you re-receive it.

<Warning>
  This method only works if no stock from that receipt has been moved or allocated. If it has, you cannot revert the receipt.
</Warning>

## Option 2: Use the Add Stock feature

If reverting the receipt is not possible, adjust the stock manually:

<Steps>
  <Step title="Select the stock line">
    In the stock list data grid, tick the box next to the stock line you want to update.
  </Step>

  <Step title="Make a negative adjustment">
    Go to **Stock Controls** and click **Negative Adjustment**. This removes the stock from the system.
  </Step>

  <Step title="Add the stock back">
    Go back to **Stock Controls** in the data grid and click **Add Stock**.
  </Step>

  <Step title="Re-enter stock details with storage unit">
    In the **Add Stock** menu, re-enter all relevant details for the stock line, including:

    * Account
    * Product code
    * Location to
    * **Storage unit**
  </Step>
</Steps>

<Info>
  You must have a reason code set up for both positive and negative adjustments to proceed with manual adjustments.
