Overview

The GMD_SAMPLING_EVENTS table is a core data object within the Oracle E-Business Suite Process Manufacturing (OPM) Product Development module (GMD). It serves as the primary transactional repository for quality sampling events. In the context of manufacturing and laboratory operations, a sampling event is a formal record of the collection of a physical sample from a lot, batch, or process for the purpose of quality testing and specification compliance. This table is fundamental to the quality management lifecycle, linking the physical act of sampling to subsequent laboratory tests, results, and disposition decisions. Its existence is critical for traceability, audit trails, and ensuring that quality decisions are based on properly documented sample collections.

Key Information Stored

The table stores metadata and descriptive information for each unique sampling occurrence. While the full column list is proprietary, the structure is anchored by the primary key, SAMPLING_EVENT_ID, which uniquely identifies each event. Typical columns in such a table would include identifiers for the source material (such as LOT_ID, INVENTORY_ITEM_ID, ORGANIZATION_ID), the reason for sampling, the person who collected the sample, and timestamps for creation and last update. It also stores status information (e.g., planned, collected, canceled) and references to the sampling plan or procedure that governed the event. The data facilitates answering core questions of what was sampled, from where, when, by whom, and why.

Common Use Cases and Queries

This table is central to quality assurance reporting and operational queries. Common use cases include generating a log of all samples taken for a specific production lot to review its quality history, or identifying samples collected within a certain date range for audit purposes. A typical reporting query would join GMD_SAMPLING_EVENTS to inventory and item tables to produce a readable sample log. For example:

  • Tracking sample status: SELECT sampling_event_id, status, creation_date FROM gmd_sampling_events WHERE lot_id = :p_lot_no ORDER BY creation_date DESC;
  • Linking samples to tests: Queries often join to related tables like GMD_SAMPLES and GMD_TEST_RESULTS to analyze the full quality data chain from sample collection to final result.
  • Operational dashboards may aggregate data from this table to monitor sampling activity volumes and trends.

Related Objects

GMD_SAMPLING_EVENTS is a parent table in a key data model. It has direct relationships with several other GMD tables. The GMD_SAMPLES table likely stores the physical sample details (like quantity, location) for each sampling event. The primary test results table, GMD_TEST_RESULTS, is typically linked via the sample or directly to the sampling event to record analytical outcomes. Furthermore, it is referenced by the primary key constraint GMD_SAMPLING_EVENTS_PK. For transactional integrity and application logic, it is accessed by various Oracle APIs and public interfaces within the GMD quality module, which manage the creation, update, and validation of sampling event data.
