NetLease - Modification preview
Overview
NetLease has a Preview button on the Lease Modification page which shows the schedule lines a modification will produce before you submit it. The preview uses the values currently entered on the page, including payment lines you haven't saved yet. It opens in a pop-up window called Modification Preview, with a read-only list titled Projected Schedule Lines.
Previewing doesn't save anything. It creates no modification record, payment records or journals, and it doesn't change the lease or its schedule. Those changes happen only when you submit the modification.
For a True Up, the preview also shows the existing lines the true up re-posts, labeled Reversal of Period (for example, Reversal of Period 3).
Prerequisites
- NetLease 2026.2.4.0 or later.
- The Preview Modification setting must be checked in NetLease > NetLease Setup > System Setup. See the steps below.
- Access to the Lease Modification page, the same access you need to create a modification.
Step-by-step process
Turn on the Preview button
- Go to NetLease > NetLease Setup > System Setup and click on the System Features subtab.
- Under the Quick Access Buttons section, check the Preview Modification checkbox to enable.
- Click Save.
Preview a modification
- Navigate to a NetLease Lease (NetLease > Lease Management > Lease List) and view the lease record and click Modify at the top or bottom of the page.
- Enter the modification as you normally would: modification type, modification effective date, lease term, discount rate and payments.
- Click Preview. If a payment line is still open in the editor, NetLease adds it first. The same checks that run when you submit also run here, so fix any errors they raise before the preview opens.
- Review the Projected Schedule Lines in the Modification Preview pop-up. The Transaction Type column shows whether each line is an Amortization line, a Modification line or a Reversal of Period line.
- Click Close. Adjust the modification if needed and preview again, or submit it by clicking Modify Lease on the Lease Modification page.
Refreshing the preview
You can refresh the pop-up for up to one hour and it re-runs the same preview. After an hour it shows "This preview has expired." Close it and click Preview again.
How the preview chooses its columns
The preview builds its columns from the Adaptive Schedule Columns Search, set under NetLease > NetLease Setup > System Setup under the General tab in Schedule Settings. If that field is blank, the preview uses the search that comes with NetLease. Columns appear in the search's order. This applies whether or not Enable Adaptive Schedule Columns checkbox is checked in NetLease Setup.
Column labels come from the search, with three exceptions. GASB, Sublease Operating and 840 leases use their own wording for some columns. Non-lease payment columns use the names set on the Non-lease payments subtab. A column without a label in the search shows the field name.
A column appears only when it meets all of the following conditions:
- It's a column in the Adaptive Schedule Columns Search.
- It's a plain schedule line field. Joined, formula, summary and function columns are skipped, because there's no saved record yet to evaluate them on.
- The lease's classification and your feature settings allow it (see "Why is a column missing?" under Troubleshooting).
- It isn't a record link or audit field (see "Columns that never appear" below).
- At least one previewed line has a value. A date column needs any date. Any other column needs a number other than zero, so a column that is blank or zero on every line is hidden, and text columns never show.
If the selected search can't be loaded, for example because it was deleted or your role can't see it, the preview shows every schedule line field used by the lease's classification instead, still subject to conditions 3-5 above.
The preview shows the schedule columns for the lease’s classification after the modification. If the modification reclassifies the lease, for example from Operating to Financing, you see the Financing columns, not the Operating ones.
Troubleshooting
Why isn't the Preview button showing?
- Preview Modification is unchecked. Check it under NetLease > NetLease Setup > System Setup, on the System Features subtab in the Quick Access Buttons section.
Why didn't the pop-up open when I clicked Preview?
- A validation message appeared. The preview runs the same checks as submitting, so fix the field it names and click Preview again.
- The payment line open in the editor couldn't be added. NetLease shows: "The payment line being edited could not be added." Finish the line or cancel it, then try again.
- Your browser blocked the pop-up. Allow pop-ups for your NetSuite domain.
Why does the preview say "The modification does not change any schedule lines"?
- The values entered produce no new or changed schedule lines. Check the effective date, the payments and the term.
Why does the preview say "Unable to preview the modification"?
- The calculation ran into an error. The message after the colon is the same error that submitting would raise. Fix the input it names.
Why is a column missing?
| Column(s) | Requirement to show |
|---|---|
| Any column | It's in the Adaptive Schedule Columns Search (or the bundled search if none is selected), and at least one previewed line has a non-zero value or a date. |
| Transaction Type | Always shown. |
| Period Number, Period Start/End Date, Remaining Periods, Lease Payment, Equivalent Monthly Payment, Remaining Payment, Discount Rate %, Total Payment, Total Lease Expense, Payment Reclass Amount | No classification or feature requirement. They only need to be in the search and have a value. |
| Uplift Percentage, Month Over Month Uplift Percentage | The modification includes an uplift, so the lines have uplift values. |
| Operating columns: Lease Expense, Interest Accretion, Allocated to Principal, Lease Liability Balance, Asset Adjustment, Gross Asset Adjustment, and the Right of Use Asset Gross/Accum./Net Balance and Net Balance columns (Operating) | The lease is Operating, or it's a multi-book lease whose second classification is Operating. |
| Financing columns: Interest Expense, Allocated to Principal, Amortization Amount, Lease Liability Balance, Asset Adjustment, Gross Asset Adjustment, and the Right of Use Asset Gross/Accum./Net Balance and Net Balance columns (Financing) | The lease is Financing or any GASB classification, or it's a multi-book lease whose second classification is one of these. |
| Posting balances: Lease Liability Balance, Right of Use Asset Gross/Accum./Net Balance and Net Balance (Posting); Current Portion of Lease Liability | The lease is Operating, Financing or GASB. These are hidden for short-term, low-value, sublease operating, 840 and cash basis leases. |
| Lease Expense/Income, Allocated To Deferred/Accrued Rent, Deferred/Accrued Rent Balance (ST/LV/Sublease) | The lease is Short-Term/Low-Value or Sublease Operating, or 840 Lease is checked on it. |
| Allocated to Interest, Interest Payable Balance | The lease is a GASB classification. GASB leases relabel several columns, for example "Lease Liability" or "Subscription Liability." |
| Cash basis leases | The classification columns above (Operating, Financing, ST/LV/Sublease, GASB and posting balances) are hidden. Payment, date and period columns can still show, as can Historical FX Rate, percentage rent and non-lease payment columns when their feature is on. |
| Second classification columns (multi-book) | Multi-Book is checked on the System Features subtab of NetLease Setup, and the lease has a secondary book or a second classification. |
| Historical FX Rate | The lease currency is different from the subsidiary's base currency. |
| Percentage rent columns (Payment, Expense, Due, Accrued, Sales, Breakpoint, Percentage) | Percentage Rent is enabled on the System Features subtab. |
| Non-Lease Payment 1, 2, 3 | Non-Lease Payments is enabled on System Features, and that payment has a name on the Non-lease payments subtab. The column uses that name as its label. |
Columns that never appear in the preview
The preview never shows the following, because none of them exist until the modification is saved and processed:
Lease, Lease Classification, the Transaction Type field, Amortization Type, Processing Status, Execution Log, every journal entry link (Journal Entry, Book Specific, LT to ST Reclass, FX Historical Adjustment, Custom Reclass, Reversal, Elimination), Bill, FX Adjustment Audit, Modification Detail, Termination Detail, Partial Expense Calculation Audit, and Processed with No Journal Entry.
Text and formula columns are skipped.
Text fields, formula columns and joined columns you add to the Adaptive Schedule Columns Search show on the lease record's schedule but not in the preview.
Why are there "Reversal of Period 3" lines on a True Up preview?
- A true up re-posts existing lines in the true-up period. The preview shows them with their new period number. Their amounts are what was originally posted.
Why doesn't the saved schedule exactly match the preview?
In a few edge cases, the result after you submit can differ from the preview:
- Two payment lines on the same date. The preview uses the first line. The saved modification uses the most recently saved payment.
- A remeasurement that nets to zero. The preview always assumes a modification journal will be created. If none is created, the period numbering of the lines after the modification, and any percentage rent carried over, can differ.
Limitations / things to be aware of
- True Up and ROU Impairment previews ignore the payment list on the page. True Ups use the payments from the final version, and ROU Impairments leave payments unchanged.
- Uplifts apply only to payments on or after the uplift date, just as they do when you submit.
- A modification is processed in the background when you submit it if the lease has more than 60 remaining periods or Trigger UEs on Schedule Generation (Slow) is checked in NetLease Setup. The preview always runs immediately, so on very long leases it can take noticeably longer to open.
