If a correction needs to be made to a lease but the previous period is already closed, you can make the changes retrospectively to ensure the figures are correct. However, the required G/L postings for the change will be recorded in the current period (on the first available day). This can be done by using the Use Posting Date Overwrite option in Lease Setup under the Accounting Settings tab - essentially acting as a catch-up journal.

This functionality respects the Allow Posting From and Allow Posting To fields found in General Ledger Setup or User Setup pages.

Example Scenario

January 2020 period is already closed. Any posting to the General Ledger is only available in February of 2020. A Lease Agreement, which was signed, activated and posted to the G/L in January of 2019 needs to be reversed.

1. From the Role Center, navigate to  Setup → Admin → Reverse G/L Postings. In the opened window, fill the From Date field as 2020-01-01, To Date as 2020-01-31 and apply the Lease No. filter to reverse only the entries the lease you need reversed.
    

1. The Reverse G/L Postings function will reverse all G/L Entries in the selected period and will overwrite the posting date to the first available day specified in General Ledger or User Setup.
2. Head to the Lease Agreement you reversed postings for and click on the General Ledger (Per Lease) button. All entries involved in the reversal will use a valid posting date. The Description field will specify that it's a reversal entry (begins with Rev.) and will contain the date of the reversed entry (ex., January 2020). The catch-up journal worked.
