How to log on SAP BW Admin. Env.

SAP R/3 and SAP BW share the same BASIS technology. SAP BW is installed as a separate instance. SAP R/3 and SAP BW cannot coexist on one database instance. Usually, the system administrator might configure one or more application servers to log on to SAP BW. The SAP BW administrator creates a logon account for you based on your role in the organization and SAP BW usage.

SAP user interface, SAPGUI, software is needed to make a connection to SAP BW for administration and to design data warehouse objects Along with the SAPGUI frontend, Microsoft Office 97 and special SAP BW frontend components are installed on the SAP BW developer and end-user workstation. After the SAPGUI installation, the system administrator sets up logon properties needed to connect the SAP BW instance from your workstation.

Depending on network and SAP BW server activity, the SAP BW startup screen might stay on the screen for a while until connection to SAP BW is established. SAP BW then sends a message back to the end user's workstation and displays the SAP BW session logon window requesting user log on information as shown below.

To complete the logon session to SAP BW, you need a client, user name, and password. SAP BW security administration staff assigns you this information based on your SAP BW interactions. Enter client, user name, and password information in the SAP BW user logon screen, as shown and Language entry is optional. SAP BW supports multiple languages. If you do not enter a language key, the default language is used. In figure below , the user is BWUSER, logged under client 100, and the selected language is English (EN). After entering this information, press the Enter key or double-click the check mark located in the upper-left corner of the logon screen.

When you log on to SAP BW for the first time, you are immediately prompted to change your password. You are asked for your initial and new password. Enter your old and new password and click OK. SAP BW confirms if your new password is valid and accepted.

SAP R/3 supports multiple clients within one instance, such as training, development, and testing. This is possible in SAP R/3 because all entities, except master data objects, are client dependent.

In SAP BW, you cannot have multiple clients because SAP BW data objects are client independent. Client 000 in SAP BW is reserved for SAP internal usage. One additional active client is defined for the rest of the SAP BW activities. The reason for a client-independent environment in SAP BW is that a data warehouse holds and shares information across all business units, organizations, or legal entities of an enterprise as well as data that does not belong to any organization such as industry business performance benchmarks and Key Performance Indicators (KPI).

Data consistency is another reason for having one single client in SAP BW. You need consistent business rules regardless of who owns the transaction data. Having clients in SAP BW will restrict or add complexity in data navigation and management across multiple clients and will introduce data quality problems.
