Overview

PA_PROJ_ELEMENT_VERSIONS_PKG is a PL/SQL package body owned by the APPS schema in Oracle E-Business Suite, classified under the Oracle Projects (PA) application. It provides the low-level maintenance API for the PA_PROJ_ELEMENT_VERSIONS entity, which stores versioned information about project elements — the hierarchical building blocks (for example, structure elements, tasks, and budgeting/forecasting components) that make up a project's definition. Each time a project element changes, the versioning model preserves a historical record rather than overwriting the prior state, enabling auditability, effective-dated reporting, and comparison of project configurations over time. The package encapsulates the insert, update, and delete operations required to keep that versioned data consistent, and it shields callers from the physical column layout and sequence maintenance associated with the underlying tables. As a VALID package body in the ETRM repository for both 12.1.1 and 12.2.2, it is an internal but important component of the Oracle Projects data-maintenance layer. Customizations should treat it as a private implementation detail rather than a public, supported API.

Key Procedures and Functions

The package body exposes three documented procedures, each targeting a single row-level DML operation against the versioned project element data:

  • INSERT_ROW — Creates a new project element version record. It is invoked when a new element version must be persisted, typically alongside the creation of a new element or the establishment of a new effective version of an existing element.
  • UPDATE_ROW — Modifies attributes of an existing project element version row. This supports corrections and attribute changes within the versioning framework.
  • DELETE_ROW — Removes a project element version record from the underlying table, used for cleanup or reversal of erroneous version data.

The metadata does not disclose formal parameter lists; the procedures should be treated as internal row-maintenance routines rather than a documented public interface. Each routine performs its own DML and relies on the standard Oracle Projects dependency set, including FND_GLOBAL for session and user context, PA_INTERFACE_UTILS_PUB for interface utilities, and the SYS.STANDARD and DUAL constructs.

Tables Accessed

The package reads and writes the following tables via APPS synonyms:

  • PA_PROJ_ELEMENT_VERSIONS — The base versioning table that holds the persisted element version records. INSERT_ROW, UPDATE_ROW, and DELETE_ROW all perform DML against this table.
  • PA_PROJ_ELEMENT_VERSIONS_S — The sequence-backed surrogate-key source. The "_S" suffix denotes the sequence object used to generate unique primary keys for new version rows, referenced directly within the package body.

The user's search term, "pa_proj_element_versions_s", corresponds to this sequence table/synonym, confirming that the package body is the primary consumer of that sequence for key generation during inserts.

Usage Notes

Because PA_PROJ_ELEMENT_VERSIONS_PKG is documented as being referenced by five other database objects yet not referencing itself as a public API, it is best understood as an internal worker package called by higher-level Oracle Projects packages. In practice it is invoked from forms-based maintenance of project elements, from concurrent programs that rebuild or version project structures, and from other PA packages that manage the project element lifecycle. Custom code should avoid calling these routines directly; instead, customizations should route through the supported public Oracle Projects APIs, since the row-level procedures assume specific transactional and key-generation context. Direct DML against PA_PROJ_ELEMENT_VERSIONS is likewise discouraged, as the versioning sequence and audit columns must remain synchronized. When troubleshooting project element version discrepancies, DBAs and developers should confirm the package is VALID and that the PA_PROJ_ELEMENT_VERSIONS_S sequence is accessible, as invalid dependencies are a common cause of failed version maintenance.
