Overview

OE_AK_SRV_DURATION_V is a lightweight dictionary view owned by the APPS schema within Oracle E-Business Suite. It belongs to the Oracle Order Management (ONT) product family and is documented in the E-Business Suite Technical Reference Manual (ETRM) as being "Used for defaulting Service Duration." The view is classified as VALID and is present in both the 12.1.1 and 12.2.2 releases as reflected in the ETRM metadata.

Functionally, this is a single-row, single-column view. Its purpose is not to report transactional service duration data from order lines, but rather to provide a controlled defaulting source. Oracle's Order Management and related service-oriented flows (for example, service contracts, serviceable order lines, and install-base integrated processes) reference this view when resolving a default value for the service duration attribute. The view abstracts the defaulting logic behind a stable object name, so callers can query it without needing to know the underlying implementation.

Because the object is a view rather than a table, it introduces no physical storage of its own. It participates in EBS reporting and integration only to the extent that defaulting engines or concurrent programs invoke it. It is not a high-volume reporting source and should not be treated as a fact or dimension table.

Underlying Base Objects

According to the documented view metadata, OE_AK_SRV_DURATION_V is defined over a single referenced base object: the DUAL synonym. DUAL is an Oracle-provided one-row, one-column virtual table available in every schema and used to return constant or expression results without referencing application data.

The documented view text is:

  • SELECT 1 FROM DUAL

This confirms the view returns exactly one row with a constant value of 1. The value 1 is aliased or exposed as the single column SERVICE_DURATION. There are no joins, filters, or bind variables in the documented definition, meaning the defaulting result is static rather than data-driven.

The relationship to DUAL is therefore purely structural: OE_AK_SRV_DURATION_V wraps DUAL to present a named, schema-qualified object (APPS.OE_AK_SRV_DURATION_V) that the Order Management defaulting framework can reference consistently. In this sense, the view behaves as an interface or placeholder object, insulating application defaulting logic from hard-coded constants.

Key Columns

The ETRM metadata documents a single exposed column:

  • SERVICE_DURATION — the sole column returned by the view. In the documented view text, this column resolves to the constant 1. It represents the defaulted service duration value supplied to Order Management defaulting routines.

No data type is enumerated in the ETRM excerpt, but given the literal expression, the column returns a numeric value. Consumers should treat it as the canonical default service duration rather than as an aggregation of actual order-line durations. Because the view selects from DUAL, SERVICE_DURATION is always non-null and always identical across all rows of the result set (of which there is exactly one).

Common Use Cases and Queries

Typical usage centers on defaulting and verification. A developer or functional analyst might query the view to confirm the default service duration applied by Order Management, or to compare the shipped default against a customized value in a client instance.

Examples of practical SQL:

  • Return the default duration: SELECT service_duration FROM apps.oe_ak_srv_duration_v;
  • Schema-qualified confirmation: SELECT apps.oe_ak_srv_duration_v.service_duration FROM dual;
  • Verification in a defaulting context: include the view in a query alongside order header or line tables to confirm the default is being resolved as expected.

Because the view is read-only and constant, it is safe to reference in PL/SQL defaulting logic, but it should not be used for performance tuning or volume-based reporting. Where customizations require a different default duration, the standard approach is to replace or extend the object via a custom view or profile option, rather than modifying the seeded definition. In all cases, changes should be validated in a non-production environment and re-documented, since the seed definition is owned by APPS and may be overwritten by patches.
