The GMP.MR_SHCL_HDR table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical data structure within the Global Manufacturing and Product (GMP) module, specifically associated with the Manufacturing Execution System (MES) or Shop Floor Control functionality. This table serves as the header record for shop floor classification data, which is essential for tracking and managing production operations, work orders, and resource allocations in a manufacturing environment. Below is a detailed breakdown of its purpose, structure, and integration within Oracle EBS.

Purpose and Functional Context

The GMP.MR_SHCL_HDR table stores classification header information used to categorize and organize shop floor activities. It acts as a parent record for detailed classification entries, enabling manufacturers to group production resources, operations, or work orders based on predefined criteria such as product type, process requirements, or quality standards. This classification system enhances traceability, reporting, and operational efficiency by allowing users to filter and analyze shop floor data systematically.

Key Attributes and Columns

While the exact schema may vary slightly between Oracle EBS 12.1.1 and 12.2.2, the table typically includes the following columns:
  • SHCL_ID: A unique identifier for the shop floor classification header.
  • SHCL_CODE: A user-defined code representing the classification (e.g., "HIGH_PRIORITY" or "TOXIC_MATERIALS").
  • DESCRIPTION: A textual description of the classification.
  • ORGANIZATION_ID: Links to the inventory organization (ORG_ORGANIZATION_DEFINITIONS) to which the classification applies.
  • ENABLED_FLAG: A Boolean flag indicating whether the classification is active.
  • CREATION_DATE and LAST_UPDATE_DATE: Audit columns tracking record creation and modification timestamps.
  • CREATED_BY and LAST_UPDATED_BY: Audit columns storing the user IDs responsible for record changes.

Integration with Other Modules

The GMP.MR_SHCL_HDR table integrates with several Oracle EBS modules:
  1. Inventory (INV): Classifications may be used to filter items or resources during material transactions.
  2. Work in Process (WIP): Work orders or operations can be tagged with classifications for prioritization or reporting.
  3. Quality (QA): Classification criteria may trigger quality inspections or compliance checks.
  4. Costing (CST): Supports cost allocation based on classified production activities.

Technical Considerations

  • Indexing: The SHCL_ID and ORGANIZATION_ID columns are typically indexed for performance optimization in queries.
  • Foreign Keys: The table may reference HR_ALL_ORGANIZATION_UNITS for organizational hierarchy validation.
  • API Usage: Custom PL/SQL APIs or Oracle's standard interfaces (e.g., GMP_SHOP_FLOOR_CLASS_PKG) often interact with this table for CRUD operations.

Customization and Extensions

In implementations, the table may be extended with custom columns (e.g., ATTRIBUTE1-20) to capture additional business-specific attributes. Reports or dashboards leveraging this data often use Oracle BI Publisher or Discoverer to visualize classification-based metrics.

Conclusion

The GMP.MR_SHCL_HDR table is a foundational component of Oracle EBS's manufacturing execution framework, enabling structured categorization of shop floor processes. Its design supports scalability, integration with core modules, and compliance with manufacturing standards, making it indispensable for complex production environments.
