Here is the documentation that should be self-explanatory.

Communication 'C'

You use a user of type Communication for communication without dialog between systems (for RFC or CPIC service users for various applications, for example, ALE, Workflow, TMS, CUA).

Dialog logon is not possible.

Service 'S'

A user of the type Service is a dialog user that is available to an anonymous, larger group of users. Generally, this type of user should only be assigned very restricted authorizations.

For example, service users are used for anonymous system access via an ITS service. Once an individual has been authenticated, a session that started anonymously using a service user can be continued as a personal session using a dialog user.

During logon, the system does not check for expired and initial passwords. Only the user administrator can change the password.

Multiple logon is allowed.

Hi Rajesh,

Service (S) User:

- 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.

Communications (C) User:

- 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.
