The CSS_DEF_LANGUAGES_B table in Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2 is a critical repository table within the Common Supportability (CSS) module. This table stores language definitions and configurations that are utilized across various EBS modules to support multilingual capabilities. The table is part of the underlying data model that enables Oracle Applications to function in a globalized environment, ensuring that language-specific settings, translations, and regional preferences are consistently applied.

Table Structure and Key Columns

The CSS_DEF_LANGUAGES_B table is structured to maintain language-related metadata. Key columns include:
  • LANGUAGE_CODE: A unique identifier for each language (e.g., 'US' for American English, 'FR' for French).
  • LANGUAGE_NAME: The descriptive name of the language (e.g., 'English', 'French').
  • NLS_LANGUAGE: The National Language Support (NLS) parameter value, which aligns with Oracle's NLS standards.
  • ENABLED_FLAG: A Boolean indicator (Y/N) specifying whether the language is active and available for use.
  • BASE_LANGUAGE_FLAG: Identifies if the language is a base language for the installation (typically 'US' for English).
  • CREATION_DATE, CREATED_BY, LAST_UPDATE_DATE, LAST_UPDATED_BY: Standard audit columns for tracking record creation and modifications.

Functional Role in Oracle EBS

The CSS_DEF_LANGUAGES_B table serves as a reference for language configurations in EBS. Its primary functions include:
  1. Multilingual Support: It provides the foundation for translating user interfaces, reports, and messages into multiple languages. Applications reference this table to determine available languages and their properties.
  2. NLS Settings Integration: The table's NLS_LANGUAGE column ensures compatibility with Oracle's globalization features, such as date formats, numeric conventions, and sorting rules.
  3. Language Enablement/Disablement: Administrators can control language availability system-wide by updating the ENABLED_FLAG column, streamlining deployment in multinational environments.

Integration with Other Modules

The table interacts with several EBS components:
  • FND_LANGUAGES: The CSS_DEF_LANGUAGES_B table often synchronizes with FND_LANGUAGES to ensure consistency in language definitions across the application stack.
  • Workflow and Alerts: Language preferences from this table influence notification templates and workflow messages.
  • Reporting Tools: BI Publisher and other reporting tools use this table to render reports in the user's preferred language.

Technical Considerations

  1. Indexing: The LANGUAGE_CODE column is typically indexed for performance optimization in language lookups.
  2. Upgrades and Patches: During EBS upgrades or patches, this table may be updated to include new language definitions or modify existing ones.
  3. Customizations: While direct modifications to this table are discouraged, extensions can reference it via APIs or views.

Conclusion

The CSS_DEF_LANGUAGES_B table is a foundational element in Oracle EBS's multilingual architecture. Its role in managing language definitions ensures seamless globalization support, enabling organizations to deploy EBS in diverse linguistic environments. Proper understanding of this table is essential for administrators and developers working with international deployments or customization projects involving language-specific functionalities.
