The EDW_GL_ACCT10_M_TEMP table in Oracle E-Business Suite (EBS) 12.1.1 or 12.2.2 is a temporary staging table typically used within the Enterprise Data Warehouse (EDW) or Oracle Financial Analytics framework. This table plays a critical role in the extraction, transformation, and loading (ETL) processes for General Ledger (GL) data, particularly in the context of data warehousing and business intelligence implementations. Below is a detailed analysis of its purpose, structure, and functional relevance.

Purpose and Context

The EDW_GL_ACCT10_M_TEMP table is designed to temporarily store General Ledger account segment combinations and related metadata during data integration processes. It acts as an intermediary table in Oracle's ETL workflows, facilitating the transformation of GL account data from the transactional EBS environment (e.g., GL_CODE_COMBINATIONS) into a format optimized for analytical reporting. This table is often leveraged by Oracle Business Intelligence Enterprise Edition (OBIEE) or Oracle Financial Analytics to ensure accurate dimensional hierarchies and aggregations.

Key Attributes and Structure

While the exact schema may vary based on customizations, the table typically includes the following columns:
  • ACCOUNT_SEGMENT1 to ACCOUNT_SEGMENT10: Represents the individual segments of the GL account combination, aligning with the Flexfield structure defined in Oracle GL.
  • ACCOUNT_DESC: A descriptive name for the account combination.
  • PARENT_ACCOUNT_ID: Used for hierarchical roll-ups in reporting.
  • EFFECTIVE_START_DATE and EFFECTIVE_END_DATE: Tracks the validity period of the account mapping.
  • STATUS_FLAG: Indicates whether the record is active, pending, or obsolete.
  • ETL_BATCH_ID: Links the record to a specific ETL job for traceability.

Integration with Oracle EBS Modules

The table interacts primarily with:
  1. General Ledger (GL): Sources data from GL_CODE_COMBINATIONS and GL_LEDGERS.
  2. Subledger Accounting (SLA): Captures account mappings for subledger journal entries.
  3. Oracle Data Integrator (ODI): Often used to populate this table during nightly ETL jobs.

ETL Workflow

  1. Extraction: Data is pulled from GL tables and other relevant sources.
  2. Transformation: Business rules are applied to derive hierarchies, descriptions, and derived attributes.
  3. Loading: Processed data is loaded into EDW_GL_ACCT10_M_TEMP before final insertion into fact/dimension tables.

Performance Considerations

Given its temporary nature, the table is often:
  • Indexed on ACCOUNT_SEGMENT* columns for faster joins.
  • Purged post-ETL completion to free up space.
  • Partitioned in large-scale deployments for manageability.

Version-Specific Nuances

In EBS 12.2.2, the table may include additional columns to support newer features like:
  • CoA (Chart of Accounts) enhancements.
  • Integration with Oracle Fusion Analytics.

Conclusion

The EDW_GL_ACCT10_M_TEMP table is a pivotal component in Oracle EBS data warehousing, enabling efficient GL account data harmonization for reporting. Its design reflects Oracle's best practices for staging data during complex ETL processes, ensuring data integrity and performance in multi-module financial analytics environments.
