# Batch Modifications & Reversals Overview

<a href="https://pxa.impact.com/student/activity/1277002?sid=0c0e3e5c-54c9-4435-9bee-ebcdccb7f292&#x26;sid_i=0?utm_source=app.impact.com&#x26;utm_medium=owned-platform&#x26;utm_content=&#x26;utm_campaign=help-center" class="button primary">Take the PXA course</a>

Use batch modifications or reversals when something about an action changes, like an order being canceled, a [disposition code](https://help.impact.com/brand/what-would-you-like-to-learn-about/platform-features/tracking/set-up-tracking/manage-disposition-codes) being used, or conversion data needing correction. This lets you change the commission a partner receives accordingly. Batch processing can also bulk-approve [open-ended](https://help.impact.com/brand/what-would-you-like-to-learn-about/platform-features/actions-and-payouts/open-ended-locking-explained) actions.

{% hint style="warning" %}
**Warning:** Modifying an action re-evaluates its commission using the contract terms active *at the time of modification*. For example, if a promo code that resulted in a $0 payout has since expired, modifying the action will recalculate the payout based on the current contract.

{% hint style="info" %}
**Dealing with incorrect locked actions:** You cannot modify or reverse actions after they lock. Your best course of action is to send a make-good to a partner via [Partner Funds Transfer](https://help.impact.com/brand/what-would-you-like-to-learn-about/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/what-would-you-like-to-learn-about/platform-features/finance/payments-withdrawals-and-balance/make-payments-to-brands) to you.
{% endhint %}

### Note these considerations:

* Actions can only be modified or reversed before their locking date.
* Partners have full transparency into any changes, including the reason for the modification or reversal.
* 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*.
* When you reverse a parent event, the child event may not reverse automatically, depending on the contract. Reverse both events separately if you want both reversed.
