Overview

The QA_CHARS table is a core master data table within the Oracle E-Business Suite Quality Management (QA) module, specifically for versions 12.1.1 and 12.2.2. It serves as the central repository for defining collection elements, which are the fundamental building blocks for data collection plans and specifications. Each record in this table represents a unique characteristic or element that can be measured, inspected, or recorded, such as a dimension, test result, or visual attribute. Its primary role is to provide a standardized, reusable definition for these elements across the Quality module, ensuring consistency in data collection and analysis.

Key Information Stored

While the provided ETRM excerpt does not list all columns, it identifies the critical primary and unique key columns that define the table's structure and integrity. The primary key for the table is CHAR_ID (via the QA_CHARS_PK constraint), which is a unique numeric identifier for each collection element. A second unique key constraint, QA_CHARS_UK1, is placed on the NAME column, enforcing that the descriptive name of each characteristic must also be unique within the system. These columns are essential for linking QA_CHARS to numerous transactional and setup tables throughout the Quality application.

Common Use Cases and Queries

This table is primarily referenced in setup and master data queries, as well as in diagnostic reporting to understand the relationships between collection elements and their usage. A common use case is to identify all defined collection elements for reporting or data validation purposes. Another critical scenario involves tracing where a specific characteristic is used across collection plans and specifications before modifying its definition. Sample SQL patterns include fetching a list of all elements or joining to related tables to see their full context.

  • Basic listing: SELECT char_id, name FROM qa.qa_chars ORDER BY name;
  • Finding usage in collection plans: SELECT pc.name plan_name, c.name char_name FROM qa.qa_plan_chars pc, qa.qa_chars c WHERE pc.char_id = c.char_id;

Related Objects

As indicated by the extensive list of foreign key relationships, QA_CHARS is a highly referenced parent table. Its CHAR_ID column is a foreign key in numerous key transactional and setup tables. Major related objects include QA_PLAN_CHARS (which assigns characteristics to specific collection plans), QA_SPEC_CHARS (which assigns them to specifications), and QA_CRITERIA (which defines acceptable values). Other important dependent tables manage actions (QA_CHAR_ACTION_TRIGGERS, QA_ACTION_LOG), value lookups (QA_CHAR_VALUE_LOOKUPS), and element relationships (QA_PC_ELEMENT_RELATIONSHIP). This wide integration underscores QA_CHARS' role as the definitive source for collection element definitions.
