# How do I reverse or correct an indexation?
## Undo an applied indexation with the wrong percentage or date, and schedule it again.
Did you apply an indexation with the wrong percentage or on the wrong date? Then you reset the rental contract, after which OWNER schedules the indexation again.

## How to reverse an indexation
### Step 1 – Open the rental contract
1. Go to **Contracts \> Rental contracts** and open the rental contract. On the right under Indexations, you can see the completed and planned indexations.
### Step 2 – Delete the new sales item
1. Go to the sales items of the rental contract.
2. Open the new sales item with the indexed rent and delete it.
### Step 3 – Make the old sales item active again
1. Open the original sales item. An end date was filled in there automatically during the indexation.
2. Remove the end date and click **Save**.
### Step 4 – Set the indexation date back
1. After an indexation, the indexation date automatically moves forward one year. In the rental contract, click the pencil and go to the **Indexation** section.
2. Set **Next indexation** to the date on which you do want to index, change the method if needed and save.
OWNER now schedules the indexation again. Does it need a different percentage or amount? Then deviate from that indexation: [Can I deviate from a scheduled indexation?](https://knowledge.owner.app/en/deviate-from-scheduled-indexation?hsLang=en)
## Had the indexation letter already been sent?
The previously sent indexation remains. So let the tenant know separately that the new indexation replaces the earlier one, for example by email. That makes it clear which rent applies.
Has a sales invoice with the wrong rent already been sent? Then correct it with a credit invoice and a new sales invoice.
**Tip:** only want to change a planned indexation that hasn't been applied yet? Then you don't need to reverse anything: simply deviate from the scheduled indexation.
