Reversing Journal Entry Accounting Preference
When the Void Transactions Using Reversing Journals preference is enabled, the Set Reversal Variance Date Equal to the Reversing Journal Date When Voided Transaction Is in a Closed Period preference is available. Check this box to require NetSuite to use the date specified in a reversing foreign currency gain and loss variances on voided transactions. If this box is not checked, NetSuite uses the current date for variance and reversal lines, rather than the date of the reversing journal entry.
To enable the Set Reversal Variance Date Equal to the Reversing Journal Date When Voided Transaction Is in a Closed Period preference, go to Setup > Accounting > Accounting Preferences. On the General subtab in the General Ledger section, check the Set Reversal Variance Date Equal to the Reversing Journal Date When Voided Transaction Is in a Closed Period box.
