Overview

The CR_ARES_MST table is a core data object within the Oracle E-Business Suite (EBS) Process Manufacturing Process Planning (GMP) module. Its primary function is to manage alternate resource definitions, a critical concept in manufacturing process planning. The table establishes and stores the relationships between a primary production resource and its designated substitutes or alternates. This enables production scheduling and execution systems to maintain operational flexibility, allowing for automatic or manual resource substitution when the primary resource is unavailable due to maintenance, breakdown, or capacity constraints, thereby supporting continuous production flow and schedule adherence.

Key Information Stored

The table's structure is defined by its primary and foreign key relationships. The core data consists of two essential resource identifiers that form the table's primary key (CR_ARES_MST_PK). The PRIMARY_RESOURCE column holds the identifier for the main or preferred resource as defined in the master resource tables. The ALTERNATE_RESOURCE column holds the identifier for a valid substitute resource that can perform the same or a similar function. A TEXT_CODE column is also present, which serves as a foreign key to the CR_TEXT_HDR table, allowing for descriptive text or notes to be associated with the specific alternate resource relationship for additional context or instructions.

Common Use Cases and Queries

This table is central to resource flexibility in process manufacturing. Common operational use cases include generating a list of all available alternates for a given resource during production scheduling, validating a proposed resource substitution in a shop floor transaction, and reporting on resource flexibility across a plant. A typical query would join CR_ARES_MST to the resource master table (CR_RSRC_MST) to retrieve meaningful resource names. For example, to find all alternates for a primary resource 'REACTOR-01':

  • SELECT a.alternate_resource, r.resource_name
  • FROM gmp.cr_ares_mst a, gmp.cr_rsrc_mst r
  • WHERE a.primary_resource = 'REACTOR-01'
  • AND a.alternate_resource = r.resource_code;

This data is also integral to the Process Planning and Manufacturing Execution systems when evaluating resource availability and constraints.

Related Objects

The CR_ARES_MST table has strong dependencies on several other GMP tables, as indicated by its foreign keys. It is fundamentally linked to the resource master tables, CR_RSRC_MST and CR_RSRC_MST_B, for both its primary and alternate resource columns, ensuring referential integrity to valid resources. The relationship to CR_TEXT_HDR provides a mechanism for attaching descriptive text. In a broader EBS context, this table's data is utilized by the Process Planning engine and would be referenced by various forms, reports, and underlying APIs within the GMP module that handle routing definitions, capacity planning, and production scheduling activities.
