Overview

The CZ.CZ_LCE_TEXTS table is a core data structure within the Oracle Configurator (CZ) module of Oracle E-Business Suite (EBS) 12.1.1 and 12.2.2. It serves as an aggregated storage repository for compiled Logic and Constraint Engine (LCE) commands. Its primary role is to optimize the performance of the configurator runtime by storing the logic for a configuration model in a pre-processed, sequential format. By storing multiple logical commands as rows within a single database field (LCE_TEXT) for a given logic set, it significantly accelerates the loading and execution of configuration logic from the database, which is critical for interactive configuration sessions.

Key Information Stored

The table's structure is designed to efficiently store and order blocks of LCE text. The key columns are:

  • LCE_HEADER_ID (NUMBER): A mandatory foreign key that identifies the specific logic set or file to which the text blocks belong. It links to the CZ_LCE_HEADERS table.
  • SEQ_NBR (NUMBER): A mandatory column that provides the correct sequence or ordering for the associated text blocks within a single LCE_HEADER_ID. Together with LCE_HEADER_ID, it forms the primary key (CZ_LCE_TEXTS_PK).
  • LCE_TEXT (VARCHAR2(2000)): Contains an actual block of compiled LCE command text that forms part of the complete logic set. The aggregation of these sequenced rows reconstitutes the executable logic for the configurator.

Common Use Cases and Queries

This table is primarily accessed by the Configurator engine itself during model initialization and runtime. Common use cases include debugging configuration logic issues and analyzing the structure of deployed configuration models. A fundamental query retrieves the full, ordered logic for a specific configuration model header:

SELECT LCE_HEADER_ID, SEQ_NBR, LCE_TEXT
FROM CZ.CZ_LCE_TEXTS
WHERE LCE_HEADER_ID = :1
ORDER BY SEQ_NBR;

For analysis or extraction purposes, the LISTAGG function (or equivalent for the database version) can be used to concatenate the LCE_TEXT column into a single CLOB for a given header, reconstructing the logical script. Performance tuning activities might involve examining the distribution and size of text blocks across different LCE_HEADER_ID values.

Related Objects

The CZ_LCE_TEXTS table has defined relationships with other key Configurator objects, primarily through its primary key and foreign key constraint.

  • Primary Key: The table is uniquely identified by the CZ_LCE_TEXTS_PK index on the columns (LCE_HEADER_ID, SEQ_NBR).
  • Foreign Key Relationship: The LCE_HEADER_ID column is a foreign key referencing the CZ_LCE_HEADERS table. This relationship ties the stored logic text blocks to their parent logic set definition.
  • Dependencies: As per the provided metadata, the table is referenced by an APPS synonym named CZ_LCE_TEXTS, which is the standard access point for EBS application code. The table does not itself reference other objects beyond the noted foreign key.
