SAP User Administration

To start user maintenance you have to use the transaction code SU01. You can create a new user or copy the existing user master. The user master contain all data and setting that are required to log on to a client. In this you can find the following tabs:
Address: Personal info and address
Logon Data: Password and validity period of the user
User Default: Language, Values for printer
Parameters: User specific values for standard fields
Roles and profiles: Roles and profiles assigned to the user
Groups: Grouping users for mass maintenance

Types of User:
Dialog User, Communication User, System User, Service User, Reference User.

User ids allow access to SAP applications. Each user must have a corresponding profile specifically assigned. In many situations, multiple composite profiles can be assigned to a user ID, depending on the roles an individual user is responsible.

Authorizations are the key building blocks of SAP security. Authorization is the process of assigning values to fields present in authorization objects. In SAP, access to all system functionality is achieved through a complex array of authorizations. Sometimes users find that they lack the necessary authorizations to perform a certain function in the system, in which case the message: “You are not authorized…” is displayed at the bottom of the screen

A Profile Generator PFCG is used to automatically generate and assign authorization profiles. The administrator can also create authorization profiles manually.

Default User ids:

User Ids Client Name
SAP* 000 and 001
DDIC 000 and 001
EarlyWatch 066
