Search Results business letter templates




The IGS_CO_LTR_PARM_TYPE table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a critical data structure within the iGears (Integrated Global Enterprise Resource System) module, specifically designed to manage parameter types for correspondence letters. This table plays a pivotal role in defining and categorizing parameters used in generating dynamic correspondence, such as letters, emails, or notifications, within Oracle EBS. Below is a detailed breakdown of its purpose, structure, and functional significance.

Purpose and Functional Context

The IGS_CO_LTR_PARM_TYPE table stores metadata about parameter types that are referenced in correspondence templates. These parameters act as placeholders, dynamically populated with runtime data (e.g., student names, dates, or financial amounts) when generating letters. The table ensures consistency in parameter definitions across the system, enabling reusable and standardized correspondence templates. It is particularly vital in modules like Student Administration (SA) or Financials, where automated communication (e.g., enrollment confirmations, fee reminders) is required.

Key Columns and Structure

The table typically includes the following columns:

  • PARAMETER_TYPE_CODE: A unique identifier for the parameter type (e.g., "STUDENT_NAME," "ENROLLMENT_DATE").
  • DESCRIPTION: A human-readable explanation of the parameter's purpose.
  • DATA_TYPE: Specifies the parameter's data format (e.g., VARCHAR2, DATE, NUMBER).
  • DEFAULT_VALUE: An optional default value if no runtime data is provided.
  • ENABLED_FLAG: A Boolean flag ("Y"/"N") to activate or deactivate the parameter.
  • CREATED_BY, CREATION_DATE, LAST_UPDATED_BY, LAST_UPDATE_DATE: Audit columns tracking record changes.

Integration with Other Components

The IGS_CO_LTR_PARM_TYPE table integrates with:

  • IGS_CO_LTR_TEMPLATE: Templates reference parameter types to define dynamic content.
  • IGS_CO_LTR_PARM_VALUE: Stores actual values for parameters during correspondence generation.
  • Oracle Workflow: Parameters may be passed to workflows for automated processing.

Technical and Business Impact

From a technical perspective, this table ensures data integrity by enforcing standardized parameter definitions. Administrators can configure new parameter types without code modifications, enhancing flexibility. For business users, it enables personalized, automated communications while reducing manual effort. For example, a university using Oracle EBS could generate thousands of admission letters with dynamically inserted student-specific data.

Version-Specific Considerations

In EBS 12.2.2, the table may include additional columns or constraints to support enhanced features like REST API integrations or cloud compatibility. However, its core functionality remains consistent with 12.1.1. Customizations or extensions to this table should be carefully managed to avoid conflicts during upgrades.

Conclusion

The IGS_CO_LTR_PARM_TYPE table is a foundational element in Oracle EBS correspondence management, bridging technical configurability with business automation needs. Its design reflects Oracle's emphasis on modularity and reuse, making it indispensable for organizations leveraging EBS for large-scale communication workflows.
