Overview

The QA_PLAN_CHARS table is a core data object within the Oracle E-Business Suite (EBS) Quality Management (QA) module. It functions as a junction or intersection table, establishing a critical many-to-many relationship between collection plans and the specific collection elements (characteristics) assigned to them. Its primary role is to define the structure of a collection plan by linking a plan (QA_PLANS) to the individual data points (QA_CHARS) that must be gathered during an inspection or data collection activity. This table is essential for configuring the content and scope of quality data collection across manufacturing, process, and service environments in EBS.

Key Information Stored

The table's structure is relatively simple, as its main purpose is to maintain relationships. The two primary columns, which together form the table's composite primary key, are PLAN_ID and CHAR_ID. The PLAN_ID column stores a foreign key reference to the unique identifier of a collection plan in the QA_PLANS table. The CHAR_ID column stores a foreign key reference to the unique identifier of a collection element or characteristic defined in the QA_CHARS table. This pairing explicitly states that a given characteristic is an active component of a specific plan. Additional columns, not detailed in the provided metadata but typical for such intersection tables in EBS, may include SEQUENCE (for ordering characteristics within a plan), ENABLED_FLAG, and CREATION_DATE/CREATED_BY columns for auditing.

Common Use Cases and Queries

This table is central to any reporting or data extraction involving the composition of quality collection plans. A common use case is generating a list of all characteristics included in a specific plan for a work instruction or data entry screen setup. Another is identifying which plans utilize a particular characteristic, which is vital for impact analysis before modifying that characteristic. A typical query would join QA_PLAN_CHARS to QA_PLANS and QA_CHARS to retrieve meaningful names.

  • List Characteristics for a Plan: SELECT pc.char_id, c.name FROM qa_plan_chars pc, qa_chars c WHERE pc.char_id = c.char_id AND pc.plan_id = :p_plan_id ORDER BY pc.sequence;
  • Find Plans Using a Characteristic: SELECT pc.plan_id, p.name FROM qa_plan_chars pc, qa_plans p WHERE pc.plan_id = p.plan_id AND pc.char_id = :p_char_id;

Related Objects

QA_PLAN_CHARS sits at the intersection of two primary master tables, as defined by its foreign key constraints. The QA_PLANS table stores the definition of the collection plan itself, including its name, type, and effective dates. The QA_CHARS table is the master repository for all definable collection elements, holding the characteristic's name, data type (e.g., number, date, lookup), and validation rules. This table is also a likely parent to transactional tables such as QA_RESULTS, which store the actual values collected for each plan-characteristic combination during an inspection. Understanding the relationship between QA_PLANS, QA_PLAN_CHARS, and QA_CHARS is fundamental to working with the Quality module's data model.
