Introduction
One of the most common frustrations in Oracle Fusion OTBI reporting occurs when Chart of Accounts segments fail to appear correctly within subject areas. Organizations often expect all configured segments to appear automatically, only to discover that OTBI displays only limited dimensions or incomplete hierarchy information.
Fortunately, this issue is usually caused by missing configuration steps related to hierarchy flattening, BI-enabled segments, flexfield deployment, or BI metadata synchronization.
This guide walks through the key Oracle Fusion OTBI configuration steps required to correctly expose Chart of Accounts segments and hierarchies within OTBI subject areas.

Understanding OTBI Subject Areas
Out of the box, Oracle Fusion OTBI subject areas typically display three mandatory Chart of Accounts segments:
- Balancing Segment
- Cost Center Segment
- Natural Account Segment
These dimensions are required within Oracle General Ledger.
Additional Chart of Accounts segments may appear automatically if organizations used Rapid Implementation during initial setup. However, manually configured environments often require additional OTBI configuration steps before custom segments become visible.
Step 1: Flatten Your Account Hierarchies
One of the most important configuration steps is hierarchy flattening.
For each Chart of Accounts segment:
- Ensure one hierarchy version is active
- Navigate to Actions
- Select Flatten
- Select Column Flattening
This process denormalizes hierarchy relationships so OTBI can query parent-child relationships more efficiently.
Hierarchy flattening should be rerun whenever hierarchy maintenance occurs.
Without flattening:
- hierarchy rollups may fail
- reporting structures may appear incomplete
- OTBI performance may degrade
Step 2: Publish Account Hierarchies
After flattening hierarchies, organizations must publish hierarchy data.
Publishing makes hierarchy metadata available to Oracle reporting tools including:
- OTBI
- SmartView
- Financial Reporting Studio
Failing to publish hierarchies often prevents reporting dimensions from appearing correctly.
Step 3: Create Segment Labels
For non-qualified Chart of Accounts segments, organizations must create segment labels.
This configuration step maps Oracle flexfield segments into BI reporting structures.
A critical requirement is the BI Object Name format.
For General Ledger segments, BI Object Names must follow this exact naming convention:
- Dim – GL Segment1
- Dim – GL Segment2 through Dim – GL Segment10
This naming syntax is extremely sensitive.
One common issue occurs when Microsoft Word or PowerPoint automatically converts:
- en dash (-)
into:
- em dash (—)
Oracle requires the standard en dash format.
Incorrect character formatting can prevent OTBI configurations from functioning correctly.
Budgetary Control Differences
Budgetary Control configurations differ from General Ledger configurations.
Unlike General Ledger:
- Budgetary Control has no mandatory segments
- only 10 BI dimensions are available
- naming conventions use XCC instead of GL
Budgetary Control BI Object Names must use:
- Dim – XCC Segment1
- through
- Dim – XCC Segment10
Organizations should carefully plan Budgetary Control segment usage because only 10 dimensions are available.
Step 4: Assign Labels to CoA Segments
Once labels are created:
- Navigate to Manage Structures
- Edit the Chart of Accounts structure
- Assign newly created labels to the appropriate segments
This connects Oracle flexfield structures to BI reporting metadata.
Step 5: Enable BI and Attach Hierarchies
Next, organizations must verify that each segment is:
- BI Enabled
- associated with a hierarchy
Navigate to:
Manage Structure Instances
Then:
- Edit the structure instance
- Verify BI Enabled is checked
- Attach the appropriate hierarchy
Without these settings, segments may fail to appear inside OTBI subject areas.
Step 6: Deploy the Flexfield
After configuration changes are completed:
- Navigate to Manage Chart of Accounts Structures
- Select Deploy Flexfield
Deploying the flexfield pushes configuration changes into Oracle Fusion metadata structures.
Organizations frequently miss this step, causing reporting configurations to remain unavailable.
Step 7: Run Required Scheduled Processes
Two critical scheduled processes must be executed after configuration changes.
Create Rules XML File for BI Extender Automation
Navigate to:
Scheduled Processes → Schedule New Process
Run:
Create Rules XML File for BI Extender Automation
Parameter:
- Essbase Application = your Chart of Accounts
Wait for this process to complete fully before proceeding.
Import Oracle Fusion Data Extensions for Transactional Business Intelligence
Next run:
Import Oracle Fusion Data Extensions for Transactional Business Intelligence
Parameter:
- ERP
This process may take significant time to complete depending on environment size.
Even empty environments may require approximately one hour.
Subject Areas Affected
Once configurations are completed successfully, additional segments become available across multiple Oracle Fusion subject areas.
Affected Financials subject areas include:
- General Ledger – Journals Real Time
- General Ledger – Transactional Balances Real Time
- Payables Invoices – Transactions Real Time
- Receivables – Transactions Real Time
- Receivables – Receipts Details Real Time
Additional Procurement and Projects subject areas may also expose new dimensions.
Fixed Assets Configuration Differences
Fixed Assets configurations behave differently from General Ledger configurations.
Key Asset Flexfields include:
- CAT# for Asset Category
- LOC# for Asset Location
- KEY# for Asset Key
Unlike General Ledger:
- hierarchy flattening is not required
- hierarchy publishing is not required
Organizations should understand these differences before attempting to troubleshoot Fixed Assets OTBI issues.
Common OTBI Configuration Mistakes
Common OTBI configuration issues include:
- hierarchy flattening not completed
- hierarchy publishing skipped
- BI Enabled not checked
- incorrect BI Object Name formatting
- flexfields not deployed
- scheduled processes not executed
- incorrect segment label assignment
Most OTBI reporting visibility issues trace back to one or more of these configuration gaps.
Final Thoughts
Oracle Fusion OTBI reporting relies heavily on proper Chart of Accounts configuration, hierarchy management, flexfield deployment, and BI synchronization.
When configurations are performed correctly, organizations gain significantly improved reporting flexibility across:
- General Ledger
- Payables
- Receivables
- Procurement
- Projects
- Budgetary Control
Understanding the relationship between Oracle flexfields, hierarchies, BI metadata, and scheduled processes is critical for building scalable Oracle Fusion reporting environments.
