Overview

APPS.AHL_UTIL_MC_PKG is a utility package within the Oracle E-Business Suite Enterprise Asset Management (EAM) and Asset Lifecycle (AHL) product family. Its designation "MC" refers to the Migration Console / Maintenance Console context in which it operates. The package provides a centralized set of low-level validation and conversion helpers used throughout the AHL schema to verify the existence of reference data (lookup codes, relationships, and item groups) and to translate between lookup codes and their human-readable meanings. As an AUTHID CURRENT_USER package, it executes with the privileges of the calling session, meaning it inherits the invoker's schema context rather than running with definer's rights. This design makes it a flexible shared utility intended to be called from other PL/SQL packages, forms-based logic, and concurrent processing rather than executed directly by end users. The package reduced duplication of common reference-integrity logic across the sixteen dependent packages that reference it.

Key Procedures and Functions

• Validate_Lookup_Code — A boolean function that validates the existence of a lookup code for a given lookup type. This is the routine most directly associated with the user search term "validate_lookup_code." It accepts a lookup type and lookup code and returns TRUE or FALSE indicating whether the code is defined.
• Convert_To_LookupMeaning — A procedure that returns the descriptive meaning of a lookup given its code. It accepts a lookup type and code, and returns the resolved meaning plus a boolean status indicator.
• Convert_To_LookupCode — The inverse of the preceding procedure. Given a lookup type and a lookup meaning, it returns the associated lookup code along with a boolean success indicator.
• Validate_Relationship — Documented in two overloaded forms. One form validates the existence of a relationship by relationship identifier and returns a boolean. The other form validates the relationship and additionally returns the associated position reference code.
• Validate_Item_Group — A procedure that validates whether a given item group exists, returning a boolean result.

Tables Accessed

The documented base tables referenced through APPS synonyms are AHL_ITEM_GROUPS_B and AHL_MC_RELATIONSHIPS. AHL_ITEM_GROUPS_B is the base table for item group definitions and is queried by Validate_Item_Group to confirm existence of a group. AHL_MC_RELATIONSHIPS stores relationship records used by the Migration Console and is queried by the Validate_Relationship overloads to confirm a relationship identifier and to retrieve the position reference code. Lookup validation and conversion routines rely on the standard Oracle lookup facilities (FND_LOOKUP_VALUES), which are not enumerated as base tables in the documented metadata.

Usage Notes

AHL_UTIL_MC_PKG is an internal utility rather than an end-user entry point. It is referenced by sixteen other packages in the AHL schema, and is therefore typically invoked indirectly through those callers.

• Forms and UI logic: AHL forms and their supporting libraries call Validate_Lookup_Code and the conversion routines to confirm user-entered codes and to render meanings before display or save.
• Concurrent programs and migration routines: Because the package supports the Migration Console relationship and item group data, batch programs processing item groups and relationships use the validation overloads to ensure referential integrity before insert or update.
• Custom code: Developers extending AHL functionality may call these routines to reuse the standardized validation behavior rather than reimplementing lookup or relationship checks.
• Return value handling: Callers must check the boolean return or status indicator; a FALSE result indicates the referenced value was not found and the calling process should handle the condition accordingly.
