The purpose of this phase is to implement all the business
process requirements based on the business blue print. The
system configuration methodology is provided in two packages
#Baseline(major scope)
#Final configuration(remaining scope)
some of the documents are unit testing, integrating testing,
gap analysis and so on.

This is comes under ASAP methodology  Phase- 3 
 Realization:
The Realization phase is broken in to two parts.
1) Your SAP consulting team helps you configure your 
baseline system, called the 
baseline configuration.
2) Your implementation project team fine-tunes that system 
to meet all your business and process requirements as part 
of the fine tuning configuration.
The initial configuration completed during the base line 
configuration is based on the information that you provided 
in your blueprint document. The remaining approximately 20% 
of your configuration that was not tackled during the 
baseline configuration is completed during the fine tuning 
configuration. Fine tuning usually deals with the 
exceptions that are not covered in baseline configuration. 
This final bit of tweaking represents the work necessary to 
fit your special needs.
Configuration Testing:
With the help of your SAP consulting team, you segregate 
your business processes into cycles of related business 
flows. The cycles serve as independent units that enable 
you to test specific parts of the business process. You can 
also work through configuring the SAP implementation guide 
(IMG). A tool used to assist you in configuring your SAP 
system in a step by step manner.
Knowledge Transfer:As the configuration phase comes to a 
close, it becomes necessary for the 
Project team to be self-sufficient in their knowledge of 
the configuration of your SAP system. Knowledge transfer to 
the configuration team tasked with system 
maintenance (that is, maintenance of the business processes 
after Go-live) needs to be completed at this time.In 
addition, the end users tasked with actually using the 
system for day-to-day business purposes must be trained.
