Check Transaction with VAT Amount cannot be Voided; Throws Warning Message, "The amounts in a journal entry must balance."

This occurs when the transaction has VAT and there is a User Event script deployed on the journal record.

The user enters a Write Check transaction at Transactions > Bank > Write Checks then assigns VAT on the line item. When the user tries to Void the check and Save the Voiding Journal, NetSuite pops up a message that says, "The amounts in a journal entry must balance."

This problem is logged under Issue 189703: Transactions > Bank > Write checks with Vat Amount > Void > The amounts in a journal entry must balance. 

There are two possible workarounds:

1. Turn off the preference for using reversing journals when voiding transactions.

-Navigate to Setup > Accounting > Accounting Preferences > General tab.

-Remove the check mark on Void Transactions Using Reversing Journals

-Click Save

*After the preference is disabled, the user can then edit the check and hit the Void button.

or

2. Delete the Check transaction, instead of voiding it.
