The ITG.ITG_BATCH_CLASS table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a custom table typically implemented by third-party solutions or customizations to manage batch processing classes within the Oracle EBS environment. While Oracle EBS provides native batch processing capabilities through Concurrent Manager, custom tables like ITG_BATCH_CLASS are often introduced to extend or enhance standard functionality for specific business requirements. ### **Purpose and Functionality** The ITG_BATCH_CLASS table is designed to categorize and manage batch jobs, allowing organizations to define logical groupings of concurrent programs based on business processes, priorities, or execution schedules. This table may store metadata such as: - **Batch Class ID**: A unique identifier for the batch classification. - **Batch Class Name**: A descriptive name for the batch category (e.g., "Financial Close," "Inventory Reconciliation"). - **Description**: Additional details about the batch class. - **Priority Level**: Defines execution precedence (e.g., High, Medium, Low). - **Scheduling Parameters**: Rules for when batches in this class should run (e.g., end-of-day, monthly). - **Active Flag**: Indicates whether the batch class is enabled for processing. ### **Integration with Oracle Concurrent Manager** In Oracle EBS, batch processing is primarily handled by the Concurrent Manager, which schedules and runs programs. The ITG_BATCH_CLASS table may integrate with Concurrent Manager by: - **Assigning Concurrent Programs to Classes**: Linking standard or custom concurrent programs to a batch class for better management. - **Enforcing Execution Rules**: Applying priority-based scheduling or resource allocation to ensure critical batches complete on time. - **Providing Reporting Insights**: Enabling administrators to track batch performance by class (e.g., success/failure rates, runtime trends). ### **Technical Structure** While the exact schema of ITG_BATCH_CLASS depends on the implementation, a typical structure might include: 

CREATE TABLE ITG.ITG_BATCH_CLASS (  
    BATCH_CLASS_ID      NUMBER PRIMARY KEY,  
    BATCH_CLASS_NAME    VARCHAR2(100),  
    DESCRIPTION         VARCHAR2(500),  
    PRIORITY            VARCHAR2(20),  
    SCHEDULE_TYPE       VARCHAR2(50),  
    ACTIVE_FLAG         VARCHAR2(1) DEFAULT 'Y',  
    CREATED_BY          NUMBER,  
    CREATION_DATE       DATE,  
    LAST_UPDATED_BY     NUMBER,  
    LAST_UPDATE_DATE    DATE  
);
### **Use Cases** 1. **Financial Period Close**: Grouping all GL, AP, and AR reconciliation programs under a single batch class to ensure sequential execution. 2. **Inventory Management**: Classifying stock movement and valuation batches to run during off-peak hours. 3. **Custom Workflows**: Coordinating interdependent batches (e.g., data extraction → transformation → loading). ### **Custom Extensions** Organizations may extend ITG_BATCH_CLASS with additional columns or related tables (e.g., ITG_BATCH_JOB) to support: - **Dependencies**: Defining prerequisite batches. - **Notifications**: Alerting stakeholders upon batch completion/failure. - **Audit Logs**: Tracking changes to batch class configurations. ### **Conclusion** The ITG.ITG_BATCH_CLASS table exemplifies how Oracle EBS can be customized to streamline batch processing. While not part of the standard EBS schema, it provides a structured approach to managing concurrent programs, improving operational efficiency and visibility. Administrators should ensure proper indexing and documentation to maintain performance and clarity in custom implementations.
