Overview

The HXC_ALIAS_TYPES table is a core data dictionary object within the Oracle E-Business Suite (EBS) Time and Labor Engine (HXC). It serves as a master repository for defining the types of alternate names, or aliases, that can be associated with various entities in the Time and Labor system. Its primary role is to provide a flexible framework for categorization, enabling the system to support multiple naming conventions or identifiers for a single entity. As indicated in the ETRM documentation, these alias types can be configured based on either a Descriptive Flexfield (DDF) context definition or a value set, highlighting the table's integration with EBS's extensibility features. This structure is fundamental for supporting complex organizational hierarchies, reporting requirements, and integration scenarios where time-related data must be identified using different keys.

Key Information Stored

The table's structure centers on uniquely identifying and describing each alias type. The primary key, ALIAS_TYPE_ID, is a unique numeric identifier for each alias type definition. While the full column list is not exhaustively detailed in the provided metadata, based on its described purpose and common patterns, the table would typically store columns such as:

The existence of a primary key constraint, HXC_ALIAS_TYPES_PK, on ALIAS_TYPE_ID is explicitly confirmed in the metadata.

Common Use Cases and Queries

This table is primarily referenced for setup validation, data integrity checks, and reporting on alias configurations. A common administrative query involves listing all configured alias types to understand the available dimensions for time entry data. For example:

  • Basic Listing: SELECT alias_type_id, name, description FROM hxc_alias_types WHERE SYSDATE BETWEEN start_date_active AND NVL(end_date_active, SYSDATE) ORDER BY name;
  • Integration Mapping: When building interfaces, developers query this table to obtain the correct ALIAS_TYPE_ID for mapping external system codes (like HR or Project Accounting identifiers) to timecard attributes.
  • Diagnostic Query: To investigate missing alias definitions, one might join HXC_ALIAS_TYPES to HXC_ALIAS_TYPE_COMPONENTS to verify that all active types have the necessary component mappings defined.

Its use is foundational during the implementation phase to define which alternate identifiers are required for time capture and approval routing.

Related Objects

The HXC_ALIAS_TYPES table sits at the top of a key relationship hierarchy within the HXC schema. The most direct dependency is established via the foreign key relationship documented in the metadata:

  • HXC_ALIAS_TYPE_COMPONENTS: This table holds the detailed components or segments that make up a specific alias type. The foreign key from HXC_ALIAS_TYPE_COMPONENTS.ALIAS_TYPE_ID references HXC_ALIAS_TYPES.ALIAS_TYPE_ID, enforcing that every component must belong to a valid alias type.

Furthermore, alias types are ultimately used in conjunction with tables such as HXC_TIME_ATTRIBUTE_USAGES and HXC_TIME_BUILDING_BLOCKS, where the actual alias values are stored against time entries. The table is also closely related to the FND_DESCRIPTIVE_FLEXS and FND_FLEX_VALUE_SETS tables, which store the DDF context and value set definitions referenced in its SOURCE_TYPE mechanism.
