Overview

ECE_LEVEL_MATRICES_UPG is a table in the EC (e-Commerce Gateway) schema within Oracle E-Business Suite, documented as a VALID object in both release 12.1.1 and 12.2.2. It belongs to the e-Commerce Gateway product, the module responsible for inbound and outbound electronic data interchange (EDI) processing and the translation of flat-file interface data into Oracle EBS application tables. The object is an upgrade or staging table, as indicated by the _UPG suffix, and it participates in the migration and mapping of level identifier information used by the gateway's transaction processing architecture.

The table stores the relationship between matrix level identifiers internal to Oracle and the corresponding external level identifiers supplied by trading partners or interface definitions. The documented physical schema lists three columns, with MATRIX_LEVEL_ID serving as the surrogate primary key (named constraint OCO_18586901). Based on the mined foreign-key structure, the object is classified heuristically as a standalone table in Data Vault modeling terms — that is, it does not act as a hub, link, or satellite connected to other reference-keyed structures. This classification is a modeling suggestion only; the table functions in practice as an independent lookup used during upgrade and interface configuration.

Key Information Stored

The documented column set is compact, comprising three attributes that together define the level-mapping relationship:

  • MATRIX_LEVEL_ID — The surrogate primary key (constraint OCO_18586901) that uniquely identifies each row. It is a system-generated identifier and is not meaningful to end users.
  • EXTERNAL_LEVEL_ID — The level identifier as defined by an external party, interface specification, or legacy source. This is a candidate business key, since it carries the partner-facing or source-system value that must be mapped to an internal level.
  • INTERFACE_TABLE_ID — Identifies the interface table to which the level mapping applies, scoping the external-to-internal mapping to a specific e-Commerce Gateway interface context.

No additional unique indexes beyond the primary key are documented for this object. The combination of EXTERNAL_LEVEL_ID and INTERFACE_TABLE_ID represents the natural business-key candidate, while MATRIX_LEVEL_ID serves purely as the surrogate. Because the table is a migration-oriented object, its contents typically reflect the state of level mappings at the time of upgrade and may be purged or archived once the upgrade is validated.

Common Use Cases and Queries

Typical usage centers on validating and reconciling level mappings during or after an e-Commerce Gateway upgrade. Common patterns include:

  • Confirming that every external level referenced by a trading partner has a corresponding row, preventing translation failures during inbound or outbound processing.
  • Comparing pre-upgrade and post-upgrade mappings to detect orphaned or duplicate external level identifiers.
  • Reporting the distinct interfaces affected by a given level mapping.

A representative query to identify duplicated external levels within an interface is:

SELECT INTERFACE_TABLE_ID, EXTERNAL_LEVEL_ID, COUNT(*) FROM EC.ECE_LEVEL_MATRICES_UPG GROUP BY INTERFACE_TABLE_ID, EXTERNAL_LEVEL_ID HAVING COUNT(*) > 1;

A second pattern joins the staging table back to the production level matrix to verify that each upgraded row has been successfully applied, using MATRIX_LEVEL_ID as the correlation key. Because the table is upgrade-specific, these queries are most relevant during migration projects rather than steady-state operations.

Related Objects

The e-Commerce Gateway schema contains the production counterparts and interface definitions that this upgrade table supports. The most significant related objects include:

  • ECE_LEVEL_MATRICES — The production-level mapping table to which ECE_LEVEL_MATRICES_UPG rows are migrated, joined on MATRIX_LEVEL_ID.
  • ECE_INTERFACE_TABLES — Defines the interface tables scoped by INTERFACE_TABLE_ID.
  • ECE_TP_HEADERS and ECE_TP_DETAILS — Trading partner definitions that consume level mappings during translation.
  • ECE_EDIFACT_* and ECE_X12_* interface tables — Transaction-specific staging tables that rely on level identifiers during conversion.
  • ECX Data Migration or upgrade concurrent programs and their associated APIs that populate and consume this staging table.

These objects collectively form the reference data layer used by the gateway's translation engine, with ECE_LEVEL_MATRICES_UPG acting as the temporary vessel during the upgrade window.
