Overview

The ECX_LEVEL_MAPPINGS table is a core data object within the XML Gateway (ECX) module of Oracle E-Business Suite (EBS) releases 12.1.1 and 12.2.2. It functions as a relational junction table that defines and manages the hierarchical mapping relationships between source and target data structures during XML document transformation and routing. Its primary role is to support the complex data mapping requirements of B2B and A2A integrations, ensuring that data elements from an inbound transaction are correctly correlated and transformed to the appropriate fields in the target EBS interface or outbound document.

Key Information Stored

The table's structure is designed to store the essential links that constitute a mapping hierarchy. Its primary key is a composite of two columns: MAP_ID and LEVEL_MAPPING_ID. The MAP_ID column is a foreign key that associates the level mapping with a specific, parent mapping definition stored in the ECX_MAPPINGS table. The LEVEL_MAPPING_ID column uniquely identifies individual mapping records within that parent mapping context. While the provided ETRM metadata does not list all columns, the table's purpose implies it stores data that defines the sequence, parent-child relationships, and potentially the transformation rules between specific nodes or segments in the source and target XML documents or data structures.

Common Use Cases and Queries

This table is central to the execution and troubleshooting of XML Gateway maps. A common use case involves analyzing the complete mapping definition for a specific transaction type to understand its data transformation logic. Database administrators and integration developers may query this table to audit mappings or diagnose integration failures where data is not populating correctly. A foundational query retrieves all level mappings for a known MAP_ID, often joining to ECX_MAPPINGS for context.

• Sample Query: SELECT * FROM ECX.ECX_LEVEL_MAPPINGS WHERE MAP_ID = <specific_map_id> ORDER BY LEVEL_MAPPING_ID;
• Reporting Use Case: Generating a list of all level mappings associated with trading partner-specific or transaction-type-specific maps to document integration interfaces.

Related Objects

The ECX_LEVEL_MAPPINGS table has a direct and critical dependency on the ECX_MAPPINGS table, which serves as the master repository for mapping definitions. The documented foreign key relationship is:

• Foreign Key (this table references): ECX_LEVEL_MAPPINGS.MAP_ID → ECX_MAPPINGS. This relationship ensures that every hierarchical mapping record is tied to a valid, parent mapping setup. The integrity of this link is enforced by the primary key constraint ECX_LEVEL_MAPPINGS_PK.

While not listed in the provided metadata, this table is also logically related to other ECX mapping tables, such as those storing the actual source and target field definitions (e.g., ECX_SRC_DOC_MAPPINGS, ECX_TRGT_DOC_MAPPINGS), with LEVEL_MAPPING_ID serving as the likely correlating key.
