Overview

The CZ.CZ_LCE_OPERANDS table is a core data structure within the Oracle Configurator module of Oracle E-Business Suite (EBS) versions 12.1.1 and 12.2.2. It stores the detailed operands for compiled Logic, Constraint, and Effect (LCE) command lines. When a runtime configurator model is compiled, the logic rules defined within it are transformed into a set of executable commands. This table holds the individual components (operands) of those commands, linking each operand to its specific command line. Its primary role is to support the runtime evaluation and processing of configuration rules, ensuring that user selections adhere to defined business logic and constraints during the configuration of complex products.

Key Information Stored

The table's structure is designed to catalog operands within the context of a compiled LCE set. The most critical columns define relationships and operand properties. The LCE_HEADER_ID identifies the specific compiled LCE set or file. The LCE_LINE_ID is a foreign key to the CZ_LCE_LINES table, pinpointing the exact command line to which this operand belongs. The OPERAND_SEQ defines the order of the operand within its line, while OPERAND_TYPE indicates its sense or role (e.g., Left-Hand Side, Right-Hand Side). The NAME column stores the actual identifier or value of the operand, which is derived from the original model nodes (CZ_PS_NODES). Standard WHO columns (CREATED_BY, CREATION_DATE, LAST_UPDATED_BY, LAST_UPDATE_DATE, LAST_UPDATE_LOGIN) track auditing information, and the DELETED_FLAG supports logical deletion of records.

Common Use Cases and Queries

A primary use case is the technical analysis and debugging of configurator logic behavior. Developers and functional consultants query this table to trace how high-level model rules are decomposed into executable operands. A common query pattern involves joining to CZ_LCE_LINES to get the full context of a command. For example, to analyze all operands for a specific LCE header and line, one would use:

• SELECT lo.* FROM cz.cz_lce_operands lo WHERE lo.lce_header_id = &header_id AND lo.lce_line_id = &line_id ORDER BY lo.operand_seq;

Another critical scenario is investigating configuration runtime errors by mapping the operands involved back to their source model elements via the NAME column and the CZ_PS_NODES table. Reporting on the structure and complexity of compiled logic for performance tuning also relies on aggregating data from this table.

Related Objects

The CZ_LCE_OPERANDS table has a direct and integral relationship with the CZ_LCE_LINES table, as indicated by the CZ_LCE_OPERANDS_N1 index on the LCE_LINE_ID and LCE_HEADER_ID columns. Each record in CZ_LCE_LINES has one or more child records in CZ_LCE_OPERANDS. The primary key (CZ_LCE_OPERANDS_PK) is a composite of LCE_HEADER_ID, OPERAND_SEQ, and LCE_LINE_ID, solidifying this dependency. As documented in the metadata, the operands are derived from the CZ_PS_NODES table, which stores the fundamental model elements. The table is also referenced by an APPS synonym (CZ_LCE_OPERANDS), which is the standard access point for EBS application code. There are no documented foreign key constraints from this table to other objects.
