Common Errors in Oracle Fusion and How to Fix Them

 

Common Errors in Oracle Fusion and How to Fix Them

In this blog post, we will discuss on the common errors in Oracle fusion and how to fix them. Please note this covers basic required stuffs and may not cover all the required steps to fix. 

Oracle Fusion Applications are powerful but complex. Whether you're working with FBDI, HDL, BI Publisher, REST APIs, or ESS Jobs, errors are inevitable. 

This blog helps you identify common Oracle Fusion errors, understand why they occur, and apply quick fixes or best practices to resolve them.

1. FBDI Upload Errors (File-Based Data Import)

Error:

"A value is missing for the required column."

Fix:

  • Open the .zip file and check the .csv inside.

  • Ensure required fields are not empty (e.g., BUSINESS_UNIT, LEDGER_ID, etc.).

  • Validate lookup values are accurate (refer to FND_LOOKUP_VALUES).

Pro Tip:

Use the latest FBDI template from Oracle documentation to ensure compatibility with the current version.

2. HDL Errors (HCM Data Loader)

Error:

The value for the attribute PersonId is invalid.

Fix:

  • Check if the referenced PersonNumber exists using:

    SELECT person_id FROM per_all_people_f WHERE person_number = 'XYZ123';

  • Make sure effective dates fall within valid ranges.

Pro Tip:

Enable diagnostics logging for HDL (via Scheduled Processes > View Logs) to see detailed error reasons.

3. BI Publisher Errors

Error:

ORA-00904: "COLUMN_NAME": invalid identifier

Fix:

  • Go to Data Model and verify all SQL column names are valid and exist in the source table.

  • Double-check if you are using an alias for complex expressions.

Pro Tip:

Use the "View Output" → "XML" option in BIP to debug missing or incorrect XML tags in the template.

4. ESS Job Failures (Enterprise Scheduler Service)

Error:

Process ended in error. Check log and output file for details.

Fix:

  • Open Scheduled Processes > View Logs.

  • Check for common issues like:

    • Missing parameters

    • Incomplete data setup

    • Invalid dates or values

Pro Tip:

Use the Diagnostic Test Framework or run "ESS Job Diagnostic Report" to analyze recurring job failures.

5. REST API Errors

Error:

401 Unauthorized or 403 Forbidden

Fix:

  • Confirm the user has the correct roles and privileges (e.g., Integration Specialist, Application Implementation Consultant).

  • Use Basic Auth or OAuth2 tokens properly in your request headers.

  • API endpoint should use correct format like:

    https://<host>/fscmRestApi/resources/latest/employees

Pro Tip:

Use Postman or cURL to test endpoints before integrating into scripts.

6. Fusion UI Errors

Error:

"You do not have permission to access this page"

Fix:

  • Check user's data access in Security Console.

  • Verify roles assigned through Abstract, Job, and Data Roles.

Pro Tip:

Run "User and Role Access Audit Report" to debug missing privileges.

7. SQL Developer Errors with Fusion Views

Error:

ORA-00942: Table or View Does Not Exist

Fix:

  • You might be querying a view that is secure (e.g., views prefixed with FND_, PER_, etc.).

Conclusion

Understanding and fixing Oracle Fusion errors is a skill that improves with time. Always:

  • Check logs and XML outputs

  • Use SQL queries to validate data

  • Refer to Oracle Support notes (MOS) and documentation
