Ensuring Financial Data Quality and Trust with OneStream

Introduction: Why Financial Data Quality Matters

Today's CFOs and controllers need to manage their critical, enterprise-wide financial data and processes as effectively as possible. That data needs to be timely, accurate, and easily accessible for insightful reporting and analysis to maintain a competitive edge. Accordingly, their corporate performance management (CPM) solutions need to be robust, scalable, and provide full integration with their ERP, HCM, CRM, and other systems.

OneStream provides market-leading data-integration and data-quality capabilities built into the platform, with seamless connections to more than 250+ unique GL/ERP systems, on-premise or in the cloud. This includes full integration with SAP, PLeX, Microsoft Dynamics, Oracle E-Business Suite, JD Edwards, PeopleSoft, NetSuite, Infor, and others, using a direct-connect framework and no-code connectors, where direct integrations are completed in days and weeks vs. months. The OneStream platform incorporates all industry-standard integration capabilities, including ODBC, RESTful and SOAP web service APIs, and custom third-party communication tools.

With full visibility from source to report, all financial data is clearly visible and easily accessible. Financial processes can be automated, reports are more accurate, and the enterprise can utilize its core financial and operational data using a single interface. With full integration to ERPs and other systems, the enterprise can simplify business processes, reduce errors and inefficiencies, and allow its teams to focus on their work vs. managing data-integration challenges.

Data Integration Requirements in CPM

Data integration is one of the most critical aspects of implementing CPM solutions. Why? Because the effectiveness of your budgeting, planning, consolidation, and reporting processes is fully dependent on getting timely and accurate data from GL/ERP, HCM, CRM, and other systems.

Common Use Cases for Data Integration in CPM

  • Loading GL trial balances for financial consolidation and reporting
  • Loading detailed capital asset data from ERP systems for capital planning
  • Drilling back to transaction details for budget vs. actuals variance analysis
  • Loading project data from ERP and project-management systems
  • Loading supplemental data for financial reporting, budgeting, or tax provision
  • Loading customer and prospect data from CRM systems for sales forecasting
  • Loading detailed employee data from HCM systems for workforce planning
  • Loading prior-period actuals to seed the budget process, or year-to-date actuals to support rolling forecasts

Most CPM applications rely on separate tools to provide integration, along with file-based integration with source systems — but key advantages come with built-in, full, direct integration between CPM and GL/ERP and other systems. A lack of robust data integration capabilities creates a multitude of problems, including manual steps, wasted resources and time, risk of errors, poor financial data quality, and a lack of traceability and auditability.

OneStream's Data Integration Capabilities

The OneStream platform is a market-leading CPM solution. It unifies and simplifies financial consolidation, close, financial and operational planning, reporting, analytics, and financial data quality for sophisticated organizations.

OneStream's unified platform enables organizations to modernize Finance, replace multiple legacy applications and cloud-based point solutions, and reduce the total cost of ownership of financial systems. What does that mean for Finance teams? It means OneStream unleashes them to spend less time on data integration and system maintenance — and more time focused on driving business performance.

Types of Data OneStream Integrates

OneStream's data-integration capabilities span many different types of data, including the following:

  • Trial balance summaries
  • Statistical / non-financial data
  • Operational data
  • Transaction detail
  • Employees, jobs, and positions
  • Leads and opportunities
  • Users and user security
  • Chart of accounts
  • Dimensional hierarchies
  • Operational metrics
  • Currency rates and more

How Data Gets Into OneStream

Data can be integrated into OneStream via several methods. The most popular — and most powerful — is the "Direct Connect" approach and no-code connectors like the SAP Connector, which enable OneStream to connect directly to source systems, load the data into OneStream, and drill back to transaction-system details. In addition to Direct Connect, file-based sources can be loaded from spreadsheets compiled by contributors, delimited files from sources without an open interface, or third-party data to enrich the analysis or driver calculation. These data files can be loaded through the interface as part of a workflow and included in the data-validation sequence.

Integrated Financial Data Quality Management

The loading, mapping, and transforming of data from source systems to CPM solutions can be cumbersome and fragmented without highly connected, business-user-managed capabilities. Data movement may be reliant on IT resources that aren't knowledgeable about the CPM model and the transformation and validations that must occur — even more problematic without the transparency and controls the business needs to support compliance. OneStream lets you avoid these issues.

OneStream has strong foundations in data quality that allow for unparalleled flexibility and visibility into the data-loading and integration process. OneStream's financial data quality is not a module or separate product, but part of the core OneStream platform — providing strict controls to deliver confidence and reliability in the quality of your data. Data-quality risk is managed using a fully auditable system; integration maps and validations control submissions from remote sites. Data may be loaded via direct connections to source databases or via any file format, and audit reports can be filtered based on materiality thresholds — ensuring one-time review at the appropriate points in the process.

Key Features of Integrated Financial Data Quality

Below are some key features of OneStream's integrated financial data quality:

  • Ability to read any GL trial balance file or report in any format with no manipulation
  • Bi-directional status updates of data collection and model changes
  • Direct integration for any open ERP or data source
  • Email or text error alerts
  • Pre-consolidation mapping and intersection validation
  • Complete audit trails from 10-K/10-Q
  • Drill-back to source GL or ERP data
  • Post-consolidation validation and confirmation
  • Ability to manage the close by requiring completeness and accuracy
  • Drill-down from calculated and aggregated accounts
  • Phased submissions

OneStream Direct Connect

OneStream can connect to and import data from any external system through a direct database connection. This means data can be imported and processed all the way through the workflow certification process — without ever having to use a source-system extract file. OneStream Integration Connectors offer direct integration with any open GL/ERP or other source system.

Below are a few of the main advantages of the Direct Connect approach:

  • Delivers fast and efficient direct-to-source system integration processes
  • Drill-down and drill-back to transactional details, including journal entries
  • Delivers direct integration with available drill-back built for any open ERP, including Oracle, PeopleSoft, JDE, SAP, Infor, Microsoft® AX/Dynamics, and more

OneStream's Direct Connect feature uses Connector Business Rules to generate and execute queries against source tables or views, pulling data into the OneStream Stage engine for mapping and transformation. Connectors can also be configured to call exposed web services from source systems using SOAP or REST APIs, and a no-code connector is available for SAP. Once data has been loaded into the OneStream Stage, it can be mapped, transformed, and summarized for loading to the financial model — and the data in Stage remains, providing drill-down capabilities from any number on a report, dashboard, or screen to review the mapping and transformation that was applied to the sourced data.

Drill-back to source paths combine the user's current point of view — such as account, entity, product, or other known attributes about the data point — to request detailed data from the data source. That data could be transactional events that made up the period-end balance, an invoice image, or other source data that was never loaded into the CPM solution.

Integrated Financial Quality Management at a Glance

Improve Integrity

Powerful pre- and post-data-loading validations and confirmations provide complete confidence in the certification process.

Enhance Productivity

Guided Workflows intuitively move business users through the entire data collection, integration, and reporting process.

Increase Transparency

100% transparency and audit trails for data, metadata, and process-change visibility from report to source.

Simplify Data Integration

Direct integration to any open GL/ERP system, including Oracle, SAP, and Microsoft Dynamics, with powerful pre-built integration Connectors and drill-back capabilities.

Drill-Down and Drill-Back to Source

The drill-down and drill-back end-user process isn't delivered through a clunky third-party tool, portal, or interface. Instead, it happens in the comfort of the standard OneStream user interface, so the end user never has to exit OneStream to see the transactional details of the ERP.

Why does this matter? Ease of use is paramount to ease of adoption and acceptance by end users who demand simplicity. The OneStream Integration Connector can move from any table to any other table, so a series of clicks that would normally be necessary to drill back to a specific transaction in an ERP system can instead be a one-click process in OneStream that immediately surfaces the most relevant details.

OneStream's drill options don't stop at displaying data in data grids, either — other options include displaying a web page via a passed URL, displaying files, text messages, and more.

Complete Transparency and Auditability

OneStream reduces internal control risk with better audit trails, drill-down and drill-back to data sources, and complete process and change visibility. OneStream provides 100-plus standard audit reports on changes to data, metadata, rules, maps, and more — and always knows who did what, when, and how. As part of the workflow, OneStream also offers the opportunity to capture process-control questionnaires to confirm the process and certify results at every level of collection and consolidation.

The OneStream Stage Database is the first stop for GL trial balances, supplemental data, and other detail, such as sales data. Mapping and pre- and post-load data-validation checks are performed to ensure accuracy and completeness before the data is loaded into the appropriate financial model.

Guided Workflows ensure end-to-end process visibility: when source data is updated, or when users make a change in the consolidation model, workflow status detects the change and alerts users to the proper state of data quality. The OneStream solution supports Sarbanes-Oxley (SOX) requirements with strict process controls, complete transparency, and certification questionnaires. Below are some examples of the built-in process controls:

  • Data and process certification and sign-off
  • Audit trails from 10-K/10-Q to GL source account and GL trial balance report or file
  • Automatic archival of all supporting files and documents
  • Document attachments and textual notations by cell, data unit, or multiple data units, archived for material disclosures
  • Support for SOX 302 and 404 certification questionnaires to identify financial process weaknesses prior to the OneStream consolidation process
