# Batch Modifications & Reversals Overview Take the PXA course 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. {% endhint %} ### Which submission method is best for you? impact.com offers you 3 methods to batch process your action data.

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.
