1. Dialog:- For Dialog User GUI Login is possible,Initial password and expiration of password and Multi GUI Logins are checked.

Individual system access (personalized)

It is possible to log on using SAP GUI. The user is therefore capable of interaction through SAP GUI.

The system checks whether the password has expired or is initial.

The user can change his or her password himself or herself.

Multiple dialog logons are checked and, where appropriate, logged.

Purpose of Dialog User is for individual human users.

2. System:- For a System User GUI Login is not possible, Initial password and expiration of password are not checked.

System-related and internal system processes.

It is not possible to log on using SAP GUI. The user is therefore incapable of interaction through SAP GUI.

The password change requirement does not apply to the passwords, that is, they cannot be initial or expired.

Only a user administrator can change the password.

Multiple logons are permissible.

Purpose of System User is for background processing and communication within a system (internal RFC calls) and between multiple systems (external RFC calls).

3. Communication:- For a Communication User login is not possible, Users are allowed to change password through some software in middle tier

Individual system access (personalized)

It is not possible to log on using SAP GUI. The user is therefore incapable of interaction through SAP GUI.

Although the system checks whether the password has expired or is initial, the implementation of the requirement to change the password, which exists in principle, depends on the logon method (interactive or non-interactive).

Purpose of this User is for external RFC calls of individual human users.These are used for login to system through external systems like web application

4. Service:- For a Service User GUI login is possible.Initial password and expiration of password are not checked.Multiple logins are allowed.Users are not allowed to change the password. Only admin can change the password.

Shared system access for a larger, anonymous group of users. Assign only very restricted authorizations for this user type.

Purpose of this User is for anonymous users. This type of users should be given minimum

authorization.After an individual authentication, an anonymous session begun with a service user can be continued as a person-related session with a dialog user.

5. Reference:- For a Reference User GUI login is not possible.Initial password and expiration of password are not checked.

User type for general, non-person related users that allows the assignment of additional identical authorizations, such as for Internet users created with transactions SU01.

Purpose of this Users are special kind of users which are used to give authorization to other users.

Hi Satish,

Dialog, Service users are login with GUI. Remaining are't possible to login with GUI.

So, maximum all users are Dialog type users.

Hi

Dialog

Individual, interactive system access.

System

Background processing and communication within a system (such as RFC users for ALE, Workflow, TMS, and CUA).

Communication

Dialog-free communication for external RFC calls.

Service

Dialog user available to a larger, anonymous group of users.

Reference

General, non-person related users that allows the assignment of additional identical authorizations, such as for Internet users created with transaction SU01. No logon is possible.

User Type

You can specify the following user types:

● Dialog (A)

○ Individual system access (personalized)

○ It is possible to log on using SAP GUI. The user is therefore capable of interaction through SAP GUI.

○ The system checks whether the password has expired or is initial.

○ The user can change his or her password himself or herself.

○ Multiple dialog logons are checked and, where appropriate, logged.

○ Purpose: for individual human users (including Internet users)

● System (B)

○ System-related and internal system processes.

○ It is not possible to log on using SAP GUI. The user is therefore incapable of interaction through SAP GUI.

○ The password change requirement does not apply to the passwords, that is, they cannot be initial or expired.

○ Only a user administrator can change the password.

○ Multiple logons are permissible.

○ Purpose: background processing and communication within a system (internal RFC calls) and between multiple systems (external RFC calls). Purpose: for example, RFC users for ALE, workflow, TMS, CUA.

● Communications (C)

○ Individual system access (personalized)

○ It is not possible to log on using SAP GUI. The user is therefore incapable of interaction through SAP GUI.

○ Although the system checks whether the password has expired or is initial, the implementation of the requirement to change the password, which exists in principle, depends on the logon method (interactive or non-interactive).

○ The user can change his or her password himself or herself.

○ Purpose: external RFC calls of individual human users.

● Service (S)

○ Shared system access for a larger, anonymous group of users. Assign only very restricted authorizations for this user type.

○ It is possible to log on using SAP GUI. The user is therefore capable of interaction through SAP GUI.

○ During a log on, the system does not check whether the password has expired or is initial.

○ Only a user administrator can change the password.

○ Multiple logons are permissible.

○ Purpose: Anonymous system access (such as for public Web services). After an individual authentication, an anonymous session begun with a service user can be continued as a person-related session with a dialog user.

● Reference (L)

○ It is not possible to log on to the system.

○ User type for general

Hi,

Dialog : Individual, interactive system access.

dialog user (BC-SEC-USR)

User and Authorization Management (BC-SEC-USR)

The user type for normal interactive (Internet) users.

Dialog (A)

User type for exactly one interactive user (all logon types including Internet users):

○ During a dialog log on, the system checks whether the password has expired or is initial. The user can change his or her password himself or herself.

○ Multiple dialog logons are checked and, where appropriate, logged.

System:

Background processing and communication within a system (such as RFC users for ALE, Workflow, TMS, and CUA).

Communication : Dialog-free communication for external RFC calls.

Service:Dialog user available to a larger, anonymous group of users.

Reference :General, non-person related users that allows the assignment of additional identical authorizations, such as for Internet users created with transaction SU01. No logon is possible.

For example, if the user does not need dialog access to the SAP System, then define it as a system user. If the user is an anonymous, public user that many different individuals can use, then define it as a service user and keep its authorizations to a minimum.

Regards
