Overview

PA_RESOURCE_OU is a table within the Oracle Projects (PA) module that stores the Operating Unit associated with a given project resource. The operating unit is derived from the resource's owning organization, effectively bridging the resource master record to the organizational unit under which it operates. This mapping is significant in multi-organization Oracle EBS implementations, where a single resource such as an employee, contractor, or piece of equipment may be associated with one or more operating units over time. The table records the temporal validity of that association through effective-dating columns, allowing the system to resolve the correct operating unit for a resource at any point in time.

Under a heuristic Data Vault classification, the metadata provided describes this object as standalone, meaning it does not carry mined foreign-key dependencies into the modeled relationship graph. In Data Vault terms this suggests a satellite-style construct: PA_RESOURCE_OU behaves less like an independent hub and more like a descriptive, time-variant attribute set attached to a resource and organization combination. Modeling it as a satellite keyed by the resource and organization business keys, with START_DATE_ACTIVE providing the effectivity, reflects both its structure and its purpose.

Key Information Stored

The documented metadata identifies a composite primary key, PA_RESOURCE_OU_PK, defined across three columns. These form the core of the table:

• ORGANIZATION_ID — Identifies the resource organization from which the operating unit is derived. It is part of the composite primary key and is central to resolving which operating unit applies.
• RESOURCE_ID — Identifies the project resource. Combined with ORGANIZATION_ID and START_DATE_ACTIVE, it uniquely locates a resource's operating unit assignment.
• START_DATE_ACTIVE — The effective start date of the operating unit association. This column makes the record date-effective, enabling historical and current resolution of a resource's operating unit.

The composite key (ORGANIZATION_ID, RESOURCE_ID, START_DATE_ACTIVE) serves as the surrogate and business key combination documented here. No separate single-column surrogate key or additional unique index is identified in the metadata. The metadata explicitly notes that the table is "not implemented in this database" in the source excerpt, indicating the reference is descriptive rather than tied to a specific installed instance.

Common Use Cases and Queries

The principal use case is resolving the operating unit for a resource within a given organization and effective date, particularly for multi-organization security and reporting. A typical query pattern retrieves the active row for a resource:

• Joining PA_RESOURCE_OU to resource or organization tables on RESOURCE_ID and ORGANIZATION_ID to attribute transactions to the correct operating unit.
• Filtering by START_DATE_ACTIVE to obtain the operating unit in effect as of a report date, supporting historical reconstruction.
• Reporting resource counts or utilization by operating unit, where the operating unit is sourced from this table rather than inferred from transaction context.
• Supporting Multi-Org access control logic by determining which operating unit owns a resource, thereby governing data visibility.

Because the object is effective-dated, queries should generally select the row with the greatest START_DATE_ACTIVE less than or equal to the date of interest.

Related Objects

The metadata classifies this object as standalone, with no mined foreign-key relationships. Related objects are therefore inferred from the business keys it carries:

• PA_RESOURCES — The resource master, joined on RESOURCE_ID.
• HR_ORGANIZATION_UNITS — The organization definition supplying OPERATING_UNIT semantics, joined via ORGANIZATION_ID.
• PA_ORGANIZATIONS — Project organizations linked through ORGANIZATION_ID.
• PER_ALL_PEOPLE_F — Where resources are people, joined through the resource's person reference.
• PER_BUSINESS_GROUPS / Operating Unit definitions — Provide the operating unit context used in Multi-Org security.

These relationships rest on the shared business keys RESOURCE_ID and ORGANIZATION_ID rather than declared constraints, consistent with the standalone classification.
