Hi arifai,

As mentioned by AdminAndrea, making changes or adjustments to historical transactions can have a negative impact on other areas of your books.  For this reason, it's best to speak with an accounting professional for the best course of action.  If you don't have an accountant, we can help you locate a ProAdvisor in your local area.

If you have other questions or concerns, please don't hesitate to reach out.  We'd be glad to assist!
