Overview

The MSC_SIMULATION_SETS table is a core data repository within the Oracle E-Business Suite Advanced Supply Chain Planning (ASCP) module. It serves as the master definition table for simulation sets, which are foundational constructs for conducting "what-if" scenario analysis. A simulation set allows planners to define and isolate a specific set of supply chain data—such as demand forecasts, safety stock policies, or resource capacities—for modeling and analysis without affecting the official, operational plan. This enables planners to evaluate the impact of potential changes before committing to them. The table's primary role is to store the unique identifiers and organizational context for each defined simulation set, acting as a parent entity for the detailed simulation data stored in related transactional tables.

Key Information Stored

The table's structure, as indicated by its primary and foreign key relationships, is designed to uniquely identify a simulation set within the multi-organization and multi-instance architecture of Oracle EBS. The critical columns forming its composite primary key (MSC_SIMULATION_SETS_PK) are:

  • SIMULATION_SET: The unique name or identifier for the simulation scenario.
  • ORGANIZATION_ID: Identifies the specific inventory organization to which the simulation data is scoped.
  • SR_INSTANCE_ID: The sourcing instance identifier, which is crucial in multi-instance deployments (like Oracle Global Order Promising) to denote the specific instance of the supply chain data.

This three-column key ensures that simulation sets are uniquely defined per organization and per sourcing instance. While the provided metadata does not list other descriptive columns, typical implementations may include columns for a user description, creation date, and status to manage the lifecycle of the simulation.

Common Use Cases and Queries

The primary use case is the creation, management, and reporting of simulation scenarios for supply chain planning. A planner might query this table to list all active simulations for a given organization. A common reporting query would join this table to child tables to analyze the scope of a simulation. For example, to retrieve the basic definition of all simulation sets for a specific instance and organization:

SELECT simulation_set, organization_id
FROM msc_simulation_sets
WHERE sr_instance_id = 1
AND organization_id = 101
ORDER BY simulation_set;

Another critical operational use case involves purging or archiving simulation data. Since child tables reference this table via foreign keys, the simulation set record in MSC_SIMULATION_SETS must often be deleted last after cleaning up dependent data in tables like MSC_NET_RESOURCE_AVAIL.

Related Objects

The MSC_SIMULATION_SETS table has a direct parent-child relationship with several planning data tables that store the actual simulation parameters. As documented, a key foreign key relationship exists with:

  • MSC_NET_RESOURCE_AVAIL: This table stores simulated net resource availability data. Its foreign key constraint on the combination of SR_INSTANCE_ID, SIMULATION_SET, and ORGANIZATION_ID ensures that all simulated resource data is explicitly linked to a valid, defined simulation set.

Logically, it is also the central reference point for other simulation data tables (such as those holding simulated demands, supplies, or sourcing rules) that would use the same composite key to associate their records with a specific simulation scenario. In application logic, this table is accessed by the planning engine and the Simulation Set user interface forms within the Oracle EBS ASCP responsibility.
