Overview

IEU_UWQM_TASK_WL_MIG is an APPS-owned PL/SQL package that forms part of the Oracle E-Business Suite Universal Work Queue (UWQ) infrastructure. In EBS 12.1.1 and 12.2.2, the UWQ framework supplies agents with a centralized, prioritized view of work items drawn from multiple source applications, including TeleService, Field Service, and Collections. The suffix "WL_MIG" indicates that this component was introduced as part of a migration of the work list generation logic, transitioning older task-selection behavior onto the current UWQ task model.

The package is classified under the ETRM as OTHER, meaning it is not a formally published public API, but an internal utility invoked by the UWQ engine. Its principal responsibility is to retrieve and order task records for a given work queue according to a priority scheme, so that the queue presents assignable work to agents in the correct sequence. It does not create, update, or delete business transactions; it is a read-oriented selection routine whose output feeds the work queue display and dispatch logic.

Key Procedures and Functions

ETRM documents a single program unit within this package:

  • GET_TASKS_BY_PRIORITY — Returns the set of tasks belonging to a work queue, ordered by priority. The routine resolves the caller's queue context, joins the relevant task data to the applicable priority definition, and delivers the ranked result set to the UWQ presentation layer. It is the primary entry point through which the migrated work list logic supplies prioritized task rows. As an internal routine, it is not intended for direct invocation by customer code.

Because only one procedure is documented, the package should be understood as a narrowly scoped helper rather than a general-purpose task API. Priority resolution is supported by the package dependency IEU_UWQM_TASK_PRIORITY_NST, which supplies the underlying priority definition used when ranking tasks.

Tables Accessed

The documented tables referenced through APPS synonyms are:

  • JTF_TASKS_B — The base table of the JTF Task Manager, which stores task header records used across CRM applications. GET_TASKS_BY_PRIORITY reads this table to obtain candidate task rows for the calling work queue. Only the base (_B) table is documented, indicating the routine typically works with task identity and key columns rather than translated or descriptive attributes.
  • PLITBLM — A PL/SQL index-by table type used within the EBS codebase for in-memory collection handling. Its presence confirms that the package buffers intermediate results, such as task identifiers or priority values, before returning the ordered list to the caller.

No insert, update, or delete activity is documented against these objects, consistent with the package's read-only role in work list generation.

Usage Notes

IEU_UWQM_TASK_WL_MIG is invoked indirectly by the Universal Work Queue runtime whenever a work queue is refreshed with tasks ordered by priority. It is not exposed through a standard concurrent program request form, nor is it listed as referenced by any other package in the ETRM dependency report, which indicates that it is called dynamically by the UWQ engine rather than through a static package reference. Its dependency on SYS.STANDARD and SYSTEM objects reflects routine PL/SQL runtime usage.

Status is VALID in the documented environment, so the package compiles cleanly against its declared dependencies. Because it is proprietary UWQ internals, customization should be avoided; functional changes to task prioritization should be delivered through supported UWQ configuration rather than by modifying this package. Administrators troubleshooting queue ordering should verify that IEU_UWQM_TASK_PRIORITY_NST and the referenced JTF_TASKS_B records are valid before investigating this code path.
