Search Results wms_dispatched_tasks




The WMS_DISPATCHED_TASKS table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical data structure within the Warehouse Management System (WMS) module. It serves as a repository for tracking and managing dispatched tasks related to warehouse operations, including picking, packing, put-away, and replenishment activities. This table plays a pivotal role in ensuring real-time visibility into task execution, resource allocation, and workflow efficiency within the warehouse environment.

Table Structure and Key Columns

The WMS_DISPATCHED_TASKS table contains several important columns that define task attributes and execution status:
  • TASK_ID: Primary key identifier for each dispatched task.
  • TASK_TYPE: Specifies the nature of the task (e.g., PICK, PUTAWAY, REPLENISH).
  • STATUS: Current state of the task (NEW, ASSIGNED, INPROGRESS, COMPLETED, CANCELLED).
  • PRIORITY: Numeric value indicating task urgency.
  • ASSIGNED_TO: References the employee/resource assigned to the task.
  • DISPATCH_TIME: Timestamp when the task was dispatched.
  • COMPLETION_TIME: Timestamp when the task was marked complete.
  • SOURCE_HEADER_ID: Links to originating documents (e.g., Move Order headers).
  • LOCATOR_ID: Identifies the warehouse location involved.
  • INVENTORY_ITEM_ID: References the item being processed.

Functional Integration

The table integrates with multiple Oracle EBS modules:
  1. Inventory Management: Tracks material movements between locations.
  2. Order Management: Supports picking tasks for sales orders.
  3. Mobile Supply Chain Applications (MSCA): Provides task data to handheld devices.
  4. Workflow Engine: Triggers status updates and notifications.

Business Process Flow

The lifecycle of records in WMS_DISPATCHED_TASKS follows this sequence:
  1. Task creation through WMS rules engine or manual dispatch
  2. Assignment to warehouse personnel via RF devices or console
  3. Real-time status updates during execution
  4. Completion confirmation with verification data
  5. Historical archiving for reporting and analytics

Technical Considerations

Key technical aspects include:
  • Indexes on TASK_ID, STATUS, and ASSIGNED_TO for performance optimization
  • Foreign key relationships with INV_ITEM_LOCATIONS, MTL_SYSTEM_ITEMS, and PER_ALL_PEOPLE
  • Triggers for audit trail and business rule enforcement
  • Partitioning strategies for high-volume implementations

Customization and Extension

Common extension scenarios include:
  • Adding custom status values for specialized workflows
  • Creating views combining task data with item/location attributes
  • Developing custom reports using BI Publisher
  • Integrating with third-party warehouse control systems

Performance Implications

The table's design impacts:
  • RF device response times during task assignment
  • Dashboard refresh rates for supervisory consoles
  • Batch processing duration for task generation routines
  • Historical data purge operations
In summary, WMS_DISPATCHED_TASKS serves as the operational backbone for warehouse task management in Oracle EBS, enabling efficient execution of material handling activities while providing the data foundation for performance monitoring and continuous improvement initiatives.
