Overview

PA_FORECAST_WF is an Oracle Projects package that provides the workflow integration layer for the project forecast (budget) approval process in Oracle E-Business Suite. Its role is to start and drive a Workflow (WF) process against a project's forecast version so that the forecast can be routed, reviewed, and approved through Oracle Workflow rather than through a purely online transaction. The package name follows the standard Oracle naming convention of the owning application (PA = Oracle Projects) plus the functional area (FORECAST) plus the technology layer (WF = Workflow).

The package header carries the RCS revision marker $Header: PAWFGFCS.pls 120.1 2005/08/19 ... mwasowic noship $, which indicates the specification is at version 120.1. The header is exposed under the APPS schema, and the compiled package is documented as API classification OTHER, meaning it is an internal or utility package rather than a supported public API for customer extension. In Oracle EBS 12.1.1 and 12.2.2 the file resides in the standard product library and is delivered with the Oracle Projects product installation.

Key Procedures and Functions

The documented specification exposes two procedures:

  • START_FORECAST_WORKFLOW — The entry point used to initiate the forecast workflow for a given project. It accepts a project identifier as input and returns the standard Oracle Workflow/API message-count, message-data, and return-status outputs, allowing callers to determine whether the workflow was launched successfully. As an OUT parameter pattern it behaves like a conventional PL/SQL API that reports status to the calling form, concurrent program, or custom code.
  • PROCESS_FORECAST — The workflow callback procedure. It follows the signature convention required by Oracle Workflow for activity functions: it receives the item type, item key, activity identifier, and function mode, and returns a result value via resultout. This procedure is invoked by the Workflow engine when the forecast process reaches its associated activity node; the function mode determines whether the activity performs its forward processing or its cancellation/cleanup logic.

Both procedures use the NOCOPY hint on their OUT parameters, an optimization documented against bug 4440895 (File.Sql.39), which standardizes large OUT parameter handling in Oracle Projects APIs.

Tables Accessed

The documented table reference for this package is PA_BUDGET_VERSIONS, accessed through an APPS synonym. PA_BUDGET_VERSIONS stores the forecast and budget version definitions for a project, including the version number, status, and related control attributes. The workflow logic reads and updates the version record to reflect the approval state of the forecast, which is why it is the single table called out in the metadata. The package is not documented as referencing any other tables, and it is referenced by no other packages, confirming its position as a leaf-level entry point rather than a shared utility.

Usage Notes

PA_FORECAST_WF is normally invoked from within the Oracle Projects forecast and budget flows. START_FORECAST_WORKFLOW is called when a user submits a forecast for approval from the Projects forms or from a related concurrent process; PROCESS_FORECAST is not called directly but is registered as the PL/SQL activity function on the forecast workflow definition, so the Workflow engine invokes it as the approval process progresses. Because the specification is marked with the noship revision comment and is classified OTHER, it should be treated as an internal Oracle implementation object. Customizations should not call PROCESS_FORECAST directly, since its parameters are owned by the Workflow engine. Any monitoring of the forecast approval — including the resolution of the user query about checking the state of a number such as the project or version identifier — is best performed through Oracle Workflow status views or the Oracle Projects forecast approval windows rather than by invoking this package directly.
