Overview

AK.AK_REGION_LOV_RELATIONS is a metadata repository table within the Application Object Library (AK) schema of Oracle E-Business Suite. It stores the configuration that defines relationships between List of Values (LOV) regions and the regions or region items that invoke them. In the Oracle EBS framework, "regions" are reusable UI constructs, and this table captures how an LOV region is bound to the item that launches it, together with the base region and attribute against which the LOV operates. The object holds status VALID and resides in the APPS_TS_TX_DATA tablespace with a PCT Free of 10.

From a Data Vault modeling perspective, the mined relationship structure classifies this object as standalone. This is a heuristic suggestion: the table does not decompose cleanly into a hub, link, or satellite pattern because it carries no strongly anchoring foreign-key hub and functions as a self-contained configuration store. Designers should treat the classification as a modeling hint rather than a definitive architectural mandate.

Key Information Stored

The table preserves a composite business identity composed of region, attribute, and base descriptors. The most significant columns are:

The surrogate primary key is defined by AK_REGION_LOV_RELATIONS_PK, spanning the region, attribute, LOV, and base columns together with DIRECTION_FLAG. The unique index SYS_C00252039 — the object the user searched for — is a business-key candidate that adds ZD_EDITION_NAME to that same column set, enforcing uniqueness across editioned rows. Audit columns such as LAST_UPDATE_DATE, LAST_UPDATED_BY, CREATION_DATE, CREATED_BY, and LAST_UPDATE_LOGIN track row lifecycle.

Common Use Cases and Queries

Typical usage centers on diagnosing LOV behavior, validating region-to-LOV bindings, and auditing configuration drift across customizations and patches. A common pattern resolves the relationships for a given launching region:

  • Query by REGION_APPLICATION_ID and REGION_CODE to list all LOV bindings for a region.
  • Join on LOV_REGION_APPL_ID and LOV_REGION_CODE to trace the target LOV region.
  • Filter by REQUIRED_FLAG or DIRECTION_FLAG to isolate mandatory or directional relationships.
  • Compare across ZD_EDITION_NAME values to detect edition-specific rows in 12.2.2.

A representative query is: SELECT REGION_CODE, LOV_REGION_CODE, BASE_REGION_CODE, DIRECTION_FLAG FROM AK.AK_REGION_LOV_RELATIONS WHERE REGION_APPLICATION_ID = :app_id. Reporting use cases include impact analysis before applying patches and reconciliation of LOV configurations between environments.

Related Objects

As a standalone configuration table, AK_REGION_LOV_RELATIONS participates in logical joins rather than enforced foreign keys. The most significant related objects are the AK region and attribute definition tables that supply the codes and application IDs referenced by the composite key. Principal relationships include:

  • AK region metadata tables keyed by REGION_APPLICATION_ID and REGION_CODE.
  • AK attribute definition tables keyed by ATTRIBUTE_APPLICATION_ID and ATTRIBUTE_CODE.
  • LOV region definitions matched on LOV_REGION_APPL_ID and LOV_REGION_CODE.
  • Base region definitions matched on BASE_REGION_APPL_ID and BASE_REGION_CODE.
  • Concurrent/audit tracking keyed by LAST_UPDATED_BY and CREATED_BY referencing FND_USER.

These joins are established on application ID and code pairs rather than declared foreign keys, reflecting the metadata-driven nature of the AK schema.
