User Data 
In the user menu Integration, you can, among other things, specify or change the user data for the DBM operator and for the standard liveCache user. To allow communication between liveCache and the SAP system, the DBM operator and the standard liveCache user must be known, as the SAP system differentiates between two types of communication:
If you want to connect to the DBM server for liveCache administration purposes, you must specify the DBM operator and password. The storage of the DBM operator data in the SAP system can be either centralized or decentralized (Central/Decentral Authorization). SAP recommends that you store user data centrally.
You must specify the standard liveCache user and password to connect to the liveCache database instance.
The DBM operator and the standard liveCache user are stored in the SAP system and in the liveCache database instance during the installation of an SAP system that uses a liveCache database instance. Further action for this liveCache database instance is not normally required.
You should, however, check that the user data exists before starting liveCache operations, and correct or complete it, if required. You can create and change the names and the passwords for the DBM operator and the standard liveCache user in the SAP system.
Caution
If the user data in the SAP system does not match the user data in the liveCache database instance, you must manually change the user data in the liveCache database instance, since saving the user data in the SAP system does not update the liveCache database instance data.
Prerequisites
In accordance with the Authorization Concept, the user was assigned one of the roles SAP_BC_LVC_ADMINISTRATOR or SAP_BC_LVC_SUPERUSER. You can reach the user menu of the user with the authorizations that correspond to his or her role.
Procedure
In the user menu, choose liveCache Assistant (transaction LC10).
Enter the name of the database connection.
Choose
liveCache 
Integration 
.To be able to change integration information, you must be in change mode. Switch to this mode, if necessary.
Check the liveCache connection information (liveCache Name, liveCache Server) for completeness and accuracy.
Choose User Data.
Configure the DBM operator and the standard liveCache user.
DBM Operator:
If the database connection already exists, the operator name selected during the installation is displayed. You can change this. Enter and confirm your chosen password. If you want to use central authorization for the user, select Central Authorization.
Standard liveCache User:
If the database connection already exists, the operator name selected during the installation is displayed. You can change this. Enter and confirm your chosen password.
Choose
Connection Save .
Result
The names and passwords are converted to upper-case letters and encrypted by the SAP system.
The user data for the DBM operator is stored in the DBCONUSR table in the SAP system. The user data for the standard liveCache user is stored in the DBCON table. If you make changes, the corresponding entries in the table DBCONUSR or DBCON of the SAP system are updated.
If the user data in the SAP system does not match the user data in the liveCache database instance, you must manually change the user data in the liveCache database instance, since saving the user data in the SAP system does not update the liveCache database instance data. In this case, do the following:
You can change the DBM operator using any client of the database manager (DBMCLI, DBMGUI, DBMRFC). For more information, see Database Manager GUI, Managing the Database Manager Operator, Database Manager CLI, Managing the Database Manager Operator).
You can change the standard liveCache user on the liveCache database instance using a query tool of your choice (such as SQL Studio, SQLCLI) by entering a corresponding SQL command (see, for example, the ALTER PASSWORD command to change the password). You can also use the Database Manager GUI (Changing the Password of a Database User).
If you have selected decentral authorization, you must also store the user data on every application server in the XUSER file. To do so, follow the procedure described in Central/Decentral Authorization.
A log entry is created in the SysLog of your SAP system (transaction SM21) that indicates that user data of a liveCache database instance has been changed.
