This we do in the realization phase : first we do base line configuration ( Like Org structure and all the standard functionality as per the business req)
final configuration means we are ready with our developments also and have done integration testing with other module for all the business process as per the BBP.
Base line and Final configuration is the third phase in ASAP methodology. The purpose of this phase is to implement all the business & process requirements based on business blue print. You customize the system step by step in two work packages: Base Line Configuration & Final Configuration.
Baseline Configuration - during the Business Blueprint phase, the Identify Baseline Scope task divides relevant business and process requirements into two main blocks. The Baseline block comprises the priority requirements of the enterprise, ensuring that they can be implemented quickly. This phase can be completed without programming or enhancements to SAP systems.
The Final configuration is an iterative process in which you set up your business requirements.You confirm that all your business requirements are met in the R/3 System. The Final configuration is a transformation process that expands the Baseline solution, defined during the Business Blueprint and Baseline configuration, through cycles (1 to n) until a solution
is found to deliver, resulting in a solution that satisfies all stated business requirements.
