This server has three clients. They are, Consultant, enduser and golden client.
Golden client: If all the solutions are perfect then they can be placed in this server as a request.

3) QUALITY SERVER: Quality of the solution will be checked by customer against their requirements and decisions will be taken. Quality and production servers will be empty and will not have any data, the data can be taken from golden client and save in this servers.

Types of SAP projects



TYPES OF SAP PROJECTS

There are six types of projects.It includes,

i) Plan 
ii) Blue Print 
iii) Build
iv) Test
