The BOM_CALENDAR_DATES table in Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2 is a critical data structure used within the Bills of Material (BOM) and Manufacturing modules to manage calendar-related information. This table stores date-specific details that are essential for scheduling, capacity planning, and production workflows. Below is a detailed analysis of its purpose, structure, and usage within Oracle EBS.

Purpose and Functional Context

The BOM_CALENDAR_DATES table serves as a repository for calendar date entries, which are referenced by other manufacturing and planning modules. It supports functionalities such as workday calculations, shift scheduling, and exception date tracking (e.g., holidays or non-working days). This table is integral to the Oracle Manufacturing Calendar, which defines operational timelines for production, resource allocation, and shop floor activities.

Key Columns and Data Structure

The table consists of several columns that define date attributes and their relevance to manufacturing operations. Key columns include:

• CALENDAR_CODE: Identifies the calendar to which the date belongs (e.g., a plant-specific or global calendar).
• EXCEPTION_TYPE: Indicates whether the date is a working day, non-working day, or holiday.
• DATE_VALUE: The actual date stored in the format YYYY-MM-DD.
• SHIFT_NUM: Specifies the shift associated with the date (if shifts are defined).
• DESCRIPTION: Optional text to describe exceptions (e.g., "Company Holiday").
• LAST_UPDATE_DATE and LAST_UPDATED_BY: Audit columns tracking modifications.

Integration with Other Modules

The BOM_CALENDAR_DATES table is referenced by several Oracle EBS modules, including:

• Capacity Planning: Determines available production days for resource utilization.
• Advanced Supply Chain Planning (ASCP): Uses calendar dates to generate feasible production schedules.
• Work in Process (WIP): Validates work order dates against calendar exceptions.
• Master Production Scheduling (MPS): Aligns production plans with operational calendars.

Data Maintenance and Customization

Calendar dates are typically maintained via the Oracle EBS user interface (Navigation: BOM > Setup > Calendar). Administrators can:

• Define multiple calendars for different facilities or business units.
• Mark dates as exceptions (e.g., holidays or maintenance shutdowns).
• Assign shifts to specific dates for granular scheduling.

Customizations may involve extending the table to include organization-specific attributes or integrating with third-party scheduling tools.

Performance Considerations

Given its frequent use in scheduling queries, the BOM_CALENDAR_DATES table should be indexed on CALENDAR_CODE and DATE_VALUE to optimize performance. Large implementations may require partitioning by date ranges for scalability.

Conclusion

The BOM_CALENDAR_DATES table is a foundational component of Oracle EBS Manufacturing, enabling precise date management for production and planning activities. Its structured data supports critical workflows, ensuring alignment between operational calendars and business requirements. Proper configuration and maintenance of this table are essential for accurate scheduling and resource optimization in manufacturing environments.
