Overview

WIP_OPERATION_VALIDATE is an Oracle Work in Process (WIP) validation package owned by the APPS schema. Its documented role is to perform pre-execution validation of work order operation changes before those changes are committed to the WIP data model. In the context of Oracle EBS 12.1.1 and 12.2.2, the package sits between the user- or process-initiated request to add or modify an operation on a discrete job and the actual persistence of that change into WIP_OPERATIONS and its associated resource records.

The package declares a single public constant, WIP_JOB_COMPLETED (value 4), which represents the job status code indicating a completed work order. This constant supports the internal logic that guards against operation changes on jobs that have already been closed out. The package does not expose general-purpose CRUD APIs; rather, it is a narrow, purpose-built validator containing two procedures that correspond to the two fundamental operation-maintenance actions available in WIP.

Key Procedures and Functions

The ETRM metadata documents two procedures in the package specification:

  • ADD_OPERATION — Validates a request to add a new operation to an existing work order. The procedure accepts a group identifier, a parent header identifier, a WIP entity identifier, and an organization identifier. It returns an error code, an error message, and a return status flag (x_err_code, x_err_msg, x_return_status). Its purpose is to confirm that the operation may legally be attached to the specified job in the specified organization before downstream logic performs the insert.
  • CHANGE_OPERATION — Validates a request to modify an existing operation on a work order. It carries the same input and output signatures as ADD_OPERATION, comprising group, parent, entity, and organization identifiers plus the standard error and status out-parameters. It confirms that the targeted operation exists in a state that permits modification.

Both procedures use the conventional Oracle EBS error-handling contract: x_return_status reports success, unexpected error, or expected error, while x_err_code and x_err_msg convey diagnostic detail to the calling program.

Tables Accessed

Validation is performed against the following APPS-synonym tables:

  • WIP_OPERATIONS — the primary store of work order operations; used to confirm existing operations and their eligible state.
  • WIP_OPERATION_RESOURCES — resource requirements attached to operations; consulted when validating the integrity of the operation-resource relationship.
  • BOM_STANDARD_OPERATIONS — the master definition of standard operations; referenced to validate that the operation being added or changed corresponds to a defined standard operation.
  • BOM_DEPARTMENTS — department definitions used to validate that the department associated with the operation is valid and active.
  • WIP_JOB_DTLS_INTERFACE — the open interface table for WIP job details; accessed in the context of interface-driven operation additions.

Usage Notes

WIP_OPERATION_VALIDATE is not documented as a public API with a formal API classification, meaning it is classified as OTHER and is not part of Oracle's published API set. Nevertheless, it is referenced by at least one other package within the APPS schema, indicating it is invoked internally, most likely by a higher-level WIP operation maintenance package that orchestrates the insert, update, and validation sequence for operations on discrete jobs.

The package is typically reached indirectly: through the Work in Process forms when an operator adds or changes an operation on a discrete job, or through interface and concurrent processing paths that load job details through WIP_JOB_DTLS_INTERFACE. Custom code should treat this package as an internal implementation detail rather than a supported integration point, because its procedures, parameter lists, and logic may change without notice across point releases. Organizations extending WIP should prefer documented APIs and validate behavior in a non-production instance before relying on this package in a custom extension.
