Overview

APPS.BIS_DIMLEVEL_ERRS_PVT is a private PL/SQL package within the Oracle Business Intelligence System (BIS) product family, which underpins the Enterprise Data Warehouse (EDW) components of Oracle E-Business Suite. The package is a diagnostic and consistency-reporting utility rather than a business-transaction API. Its stated purpose, as recorded in the source header, is to report inconsistencies in the dimension levels of the EDW, including conditions such as a missing table for values, a missing primary key, and anomalies in the start_date and end_date columns of dimension-level definitions.

The package is classified as a private (PVT) package, meaning its procedures are intended for internal use by other EDW collection or validation routines rather than as a supported public interface for customer extensions. It is declared with AUTHID CURRENT_USER, so execution privileges and name resolution follow the invoking schema. The current documented version dates to December 2002 and reflects the older EDW lineage of the product, though the object remains present in 12.1.1 and 12.2.2 installations.

Functionally, BIS_DIMLEVEL_ERRS_PVT operates as a lightweight audit helper: it opens a log file, appends diagnostic text, and produces a consolidated error report keyed by dimension level. The package is explicitly documented as having only limited error handling for file activities, which is an important operational caveat when it is scheduled in batch environments.

Key Procedures and Functions

The package exposes three documented procedures. No parameter lists are reproduced here; only the documented purpose of each is described.

• FILE_OPEN — Opens the diagnostic output file used to capture dimension-level inconsistencies. It accepts an optional file name and returns a UTL_FILE file handle to the caller. The default file name is the package constant EDW_ERRORS, defined as 'DIMLEVELERRORS.log'.
• WRITE_TO_FILE — Writes a supplied text string to an already-open file handle. It is the low-level output primitive used by the reporting logic to append individual error messages to the log.
• REPORT_ERRORS — The principal driver procedure. It inspects dimension-level metadata for inconsistencies and writes the resulting findings to the log. Both the dimension level name and the target file name are optional, allowing a full sweep or a targeted check of a single dimension level.

Tables Accessed

The documented reference list identifies two underlying objects accessed through APPS synonyms: UTL_FILE and V$PARAMETER.

• UTL_FILE — The Oracle-supplied PL/SQL file I/O package. BIS_DIMLEVEL_ERRS_PVT depends on it to create, open, and write the DIMLEVELERRORS.log output file. Because UTL_FILE operates under the database server's directory and privilege model, the package requires a valid UTL_FILE_DIR (or directory object) configuration and appropriate privileges for the invoking user.
• V$PARAMETER — The dynamic performance view exposing initialization parameters. Reference to this view is consistent with the package validating the database environment, for example confirming that the UTL_FILE output directory parameter is configured before attempting to open the log file.

The package additionally reads the EDW dimension-level metadata structures it audits, though the excerpted metadata does not enumerate those objects explicitly.

Usage Notes

BIS_DIMLEVEL_ERRS_PVT is not exposed through an E-Business Suite form and is not registered as a concurrent program in its own right. It is invoked programmatically by EDW collection and validation routines, or directly by administrators and technical consultants executing the REPORT_ERRORS procedure from SQL*Plus or a custom concurrent-program wrapper during EDW setup, data-load troubleshooting, or post-patch verification. Because it is a private package with no downstream dependents listed, it should be treated as internal infrastructure: customization against it is unsupported, and Oracle may change or remove it without notice. Administrators invoking it should verify UTL_FILE directory configuration beforehand, ensure the APPS schema has write access to the target directory, and review the generated DIMLEVELERRORS.log for dimension-level defects. Given the limited error handling noted in the source, exceptions during file operations should be anticipated and wrapped by the calling program. In the context of a site such as "EALTHCARE PRIVATE LIMITED," this object would surface only during EDW-related diagnostics and would not affect day-to-day transactional processing.
