You can change the commission a partner receives for an action by submitting reversals or modifications. These are commonly used when something about an action has changed, like an order gets canceled, a [disposition code](https://help.impact.com/brand/platform-features/tracking/set-up-tracking/manage-disposition-codes) is used, or the reported conversion data for an action is incorrect. Batch processing can also be used to bulk approve [open-ended](https://help.impact.com/brand/platform-features/actions-and-payouts/open-ended-locking-explained) actions.

{% hint style="warning" %}
**Warning:** Active contract rules at the time of modification will be applied. For example, if a promo code exception was in effect when the action occurred (resulting in a $0 payout) but has since been removed or expired from the contract at the time of modification, the payout will be adjusted according to the terms of the partner’s currently active contract.
{% endhint %}

Actions can be modified or reversed at any time before the locking date of the action, and partners have transparency in their reporting to see any changes made, including the reasons for modifications or reversals. impact.com allows a maximum of 1,000 modifications per action; if you need to make more than that, [contact support](https://app.impact.com/support/portal.ihtml).

When modifying actions that have an *original revenue currency* different from your *account currency*, the modification amount should always be submitted in the *action's original revenue currency*.

#### Common batch processing use cases

* **Returned orders or items** — Most brands prefer not to pay commissions on orders that are returned, since the revenue from that action is never actually realized.
* **Canceled actions** — If the event that took place was subsequently canceled, then you can choose to reverse the action in order to not pay out commissions.
* **Fraud** — If you see activity from a partner that goes against the terms and conditions outlined in your contract, then you can choose to reverse an action. Some common examples include actions from a stolen credit card, trademark bidding, or cookie stuffing.
* **Open-ended locking** — If you have [open-ended locking](https://help.impact.com/brand/platform-features/actions-and-payouts/open-ended-locking-explained) set up in your template terms for actions like reservations or bookings, you can modify these actions after some time has passed in order to approve and lock the action.

You can create a .csv or .xml file to process action modifications and reversals (sometimes referred to as *Returns*) in bulk and submit it to impact.com via FTP or email. When reversing a parent event, the child event is not always automatically reversed (depending on the contract), hence it is best practice to reverse parent and child events individually should you want both events reversed.

**Correcting locked actions:** You cannot modify or reverse actions after they lock. Your only course of action is to send a make-good to a partner via [Partner Funds Transfer](https://help.impact.com/brand/platform-features/finance/partner-funds-transfer/transfer-funds-to-a-partner), or to request the partner [send a make-good](https://app.gitbook.com/s/b2rE79d9UhOKZQLgzSqx/platform-features/finance/payments-withdrawals-and-balance/make-payments-to-brands) to you.
