Overview

The OKL_RULES_DFF table is a core data object within the Oracle E-Business Suite (EBS) Lease and Finance Management (OKL) module. It functions as a descriptive flexfield (DFF) base table, specifically designed to store structured, user-defined attributes for business rules. As indicated in the ETRM documentation, this table is a copy of the OKL_RULES_B table, created explicitly to facilitate the definition of custom fields for rules within the Contracts for Lease functionality. Its primary role is to extend the standard rule data model, allowing implementations to capture additional, implementation-specific information pertinent to lease and finance contract rules without modifying the core application code. This enables tailored configurations to meet unique business requirements.

Key Information Stored

The table's structure is centered on linking custom attributes to a specific rule instance. The most critical column is the ID column, which serves as the primary key (OKL_RULES_DFF_PK) and uniquely identifies each row of flexfield data. This ID column corresponds to the primary key of a record in the base rule table. Another essential column is RGP_ID, which is a foreign key linking to the OKC_RULE_GROUPS_B table. This relationship ties the flexfield data to a specific rule group. Beyond these key columns, the table contains a standard set of descriptive flexfield columns (typically named ATTRIBUTE1-20, CONTEXT, and various SEGMENT columns) that hold the actual user-defined data, as well as standard WHO columns (CREATED_BY, CREATION_DATE, LAST_UPDATED_BY, LAST_UPDATE_DATE, LAST_UPDATE_LOGIN) for auditing.

Common Use Cases and Queries

The primary use case for OKL_RULES_DFF is to query or report on the custom attributes defined for lease contract rules. For instance, an organization might store a "Regional Compliance Code" or "Internal Risk Rating" against a rule. A common query pattern involves joining this table to the base rule table to fetch both standard and custom data. A typical SQL pattern for reporting would be:

  • SELECT r.rule_number, rdf.attribute1 AS custom_field, rdf.context
  • FROM okl_rules_b r, okl_rules_dff rdf
  • WHERE r.id = rdf.id
  • AND rdf.attribute1 IS NOT NULL;

Data in this table is primarily maintained via the Oracle EBS application's user interface when configuring or entering rules, where the defined descriptive flexfield segments are presented. Direct DML operations on this table are strongly discouraged outside of approved data migration scripts, as they bypass application validation logic.

Related Objects

OKL_RULES_DFF has a direct and integral relationship with several key objects in the OKL module. Its most significant relationship is the foreign key constraint linking the RGP_ID column to the OKC_RULE_GROUPS_B table, which manages rule groups. Fundamentally, every record in OKL_RULES_DFF is associated with a corresponding record in the OKL_RULES_B table via the shared ID primary key, as it is a direct copy for DFF purposes. This table is also referenced by various application forms, views, and PL/SQL APIs within the OKL module that handle rule processing and contract lifecycle management, ensuring the custom attributes are available to the application logic.
