Login Parameters
To invoke a Data Engine function, you must enter login parameters and then other required parameters. For functions without Session in their names, you enter Windchill Risk and Reliability user account information for the login parameters. For functions with Session in their names, you enter a session token for the login parameter.
Login Parameters for User Accounts
Functions without Session in their names require the following login parameters:
UserName—The user name of the Windchill Risk and Reliability account for login. This value is not case-sensitive.
Password—The password for this Windchill Risk and Reliability account name. This value is case-sensitive.
GroupName—The group to which this Windchill Risk and Reliability user belongs. This value is case-sensitive.
* 
If the group name is not specified and the user belongs to only one group, that group is used. Otherwise, an error is returned.
Login Parameters for Sessions
Functions with Session in their names require a single login parameter:
SessionToken—The token string returned by the GetSessionToken function. Session tokens allow you to write programs that do not need to store user account information. For more information, see GetSessionToken Function.
