Longview v26.4 Software Release Notes
This document describes enhancements and changes to Longview version 26.4
Announcements
- Simplified Hierarchy Building in Partitioned Dimensions. Longview Application Framework now simplifies hierarchy management in partitioned dimensions. A new PARTITION parameter in CREATE SYMBOL, combined with automatic leaf-to-virtual-parent conversion in both CREATE SYMBOL and ASSIGN SYMBOL commands, streamlines building complex hierarchies.
- Enhanced Credential Security for REST Integration. Longview Data Servers now support password-type system attributes for secure credential management in REST commands. Password attributes are automatically masked and only resolve in event rules or batch mode with Service Account users, strengthening API security for automated workflows and third-party integrations.
- Tax Rate Year Flexibility. Longview Tax now supports configurable future tax rate years up to 99 years globally (ASC and IAS Provision only). This enhancement accommodates multi-year tax rate changes mandated by regulatory updates—such as the German corporate tax reforms spanning 2028–2032—without requiring custom workarounds or system reconfiguration.
- Period Management and System Performance: Tax Administrators can now safely delete inactive scenario, compliance, and plan periods to optimize performance. Combined with database query optimizations for automation calculations and editors, these improvements enhance responsiveness for systems with accumulated multi-year data and large automation definitions.
- Improved Administrative Efficiency: Server Manager exports configuration settings to Excel. Data Locks, User Submissions, and Events apps support multi-user filtering and description filters. Tax Calculations app introduces pre-configured profiles that automatically populate all associated calculations
- Pillar Two and Transfer Pricing: Substance-Based Income Exclusion automations now copy automatically during Pillar Two rollovers, streamlining year-end compliance workflows.
insightsoftware continues to focus our efforts on providing the greatest value in our product investment. As part of this effort, we began an initiative in 2020 to deprecate certain features that were legacy in nature and could be replaced with newer components that offered greater functionality and improved user experience.
The following components are deprecated as part of the current release:
Longview Legacy Non-HTML5 Dashboard: Deprecated as of version 25.2 now that cards on the HTML5 Longview dashboard can be manually or automatically refreshed.
Third-party authentication: Deprecated as of version 25.3 as Longview now supports the Longview SSO service, which provides a more industry-standard approach to Single Sign-On authentication.
The following supported platforms are deprecated:
Windows Server 2019 End of Support: Longview does not support Windows Server 2019. The last version of Longview that supports Windows Server 2019 is 26.1.
Enhancements Added in Longview 26.4
Longview 26.4 contains enhancements in the following areas:
- Longview Application Framework
- Longview Data Servers
- Longview Platform
- Longview Server Manager
- Longview Solutions Framework
- Longview Tax
- Longview Tax – Pillar Two
Longview Application Framework
| Enhancement | Description |
|---|---|
| LV-14726 |
A new function, IsServerMathOn(), has been added to the Longview Application Framework to verify whether ServerMath is enabled before executing dependent operations. This function returns 1 if ServerMath is ON and 0 if ServerMath is OFF. Example: Create Variable nServerMathStatus as NUM Set Variable nServerMathStatus = IsServerMathOn() |
| LV-14895 |
The CREATE SYMBOL command in the Longview Application Framework now includes an optional PARTITION parameter for creating symbols in partitioned dimensions. Example: CREATE SYMBOL ENTITIES TORONTO "Toronto" Standard Manual Credit PARENT Canada "0" 4 PARTITION 2 |
| LV-14959 | The ASSIGN SYMBOL and CREATE SYMBOL commands now automatically convert a leaf symbol to a virtual parent when that symbol has partition -1 and receives child symbol assignments, enabling new hierarchy structures in partitioned systems without manual configuration. |
| LV-15234 | The CREATE SYMBOL and ASSIGN SYMBOL commands now allow assigning newly created or unparented symbols—provided they have a partition of -1 under virtual parents with partition -1, enabling alternate hierarchies in partitioned dimensions without requiring SQL scripts. |
Longview Data Servers
| Enhancement | Description |
|---|---|
| LV-14942 | Longview now supports password-type system attributes for secure credential management in REST commands: REST ExecuteGet, REST ExecutePost, REST ExecutePut, and REST SetRequestHeader. Password attributes can be created in Application Administrator or programmatically using the CREATE ATTRIBUTE command. Password attributes resolve only when procedures are run via event rules or in batch mode with a Service Account user. |
Longview Platform
| Enhancement | Description |
|---|---|
| LV-14802 | Customers can now retrieve deployed Longview and Longview SSO version information through an updated GetServerInfo web action and a new Longview SSO API endpoint. |
Longview Server Manager
| Enhancement | Description |
|---|---|
| LV-14941 | Server Manager now allows administrators to export server configuration settings to an Excel file, enabling easier comparison between systems and sharing of configuration data. |
Longview Smart Client
| Enhancement | Description |
|---|---|
| LV-14963 | The Data Locks and User Submissions apps now support multi-user filtering, allowing administrators to select multiple users from a dropdown and view items owned by any of the selected users. |
| LV-15204 | Description filters have been added to the Data Locks, User Submissions, and Events apps, allowing administrators to filter records by description and sort results chronologically for easier review and troubleshooting. |
Longview Solutions Framework
| Enhancement | Description |
|---|---|
| LV-14467 |
The database queries used when working with automations in Longview Tax and Transfer Pricing have been optimized. These improvements enhance the responsiveness of automation calculations and the automation editor, particularly when your system contains a large number of automation definitions across multiple time periods. The performance gains affect:
There is no change to functionality or calculation results—these improvements are purely performance-focused. |
Longview Tax
| Enhancement | Description |
|---|---|
| LV-14488 | You can now safely delete inactive historical time periods in Longview Tax that you no longer need. When your systems accumulate tax data over many years, performance can slow down. This new feature lets Tax Administrators remove inactive scenario periods, compliance periods, and plan periods to keep the system running smoothly. |
| LV-14545 |
Longview Tax now supports configurable future tax rate years, allowing you to accommodate multi-year tax rate changes mandated by regulatory updates. Instead of being limited to 5 years, administrators can now configure the system to support up to 99 future tax rate years globally—ensuring your deferred tax calculations accurately reflect legislation like the German corporate tax changes spanning 2028–2032. Note: This is currently available in ASC and IAS Provision only. |
| LV-14615 | The Tax System Settings Editor has been streamlined by removing unused parameters, reducing complexity and improving administrator usability. |
| LV-14960 | The Tax Calculations app now includes a profile drop-list to select pre-configured tax calculation profiles, automatically populating all associated calculations in a single action. |
Longview Tax – Pillar Two
| Enhancement | Description |
|---|---|
| LV-14842 | Substance-Based Income Exclusion automations now copy automatically during Pillar Two rollovers. |

| LV-14873 |
When using consolidated (or sub-consolidated) interim ETR calculations with segment hierarchies in ASC MRP, tax rates were not being consistently applied to child segments when some segments had no net income before tax. The system now pushes the calculated interim current and deferred tax rates from the parent SEGMENTST level down to all descendant segments, ensuring consistent and accurate tax rate application across the entire segment hierarchy. |
