Voiding a check from 2017

[northside]

We have a check that have never come through the bank in over a year so my treasurer wants me to void it.
When I voided it, it wants to make an accounting transaction in 2017. Since I have already closed that month for the church,
what do I need to do?

In Versions 11.55 and prior, you would need to go to Accounting > Fund Accounting > Modify Unposted Transactions and change the posting month of that void transaction to one of your open months so it can be posted.

In Version 12, it is possible to reopen that closed month, post the void, then re-close those months (or not).
