SAP BusinessObjects Business Intelligence Platform 4.0 (BI 4.0) introduces a 64-bit Web Intelligence Processing Server (WIPS) that can load 64-bit database drivers. This greatly increases the resources available to the WIPS and benefited many database connection types.
There was no 64-bit Windows version of the SAP BAPI libraries with the initial release of BI 4.0 though so the WIPS process had to utilize the 32-bit Connection Server (CS32) for connectivity to SAP BAPI.
SAP BusinessObjects Business Intelligence Platform 4.1 SP01+ (BI 188.8.131.52) introduces an updated SAP BAPI driver for connectivity to SAP Business Warehouse (BW) on Windows. This driver allows for the 64-bit WIPS server to load the SAP BAPI driver in process, or in Library mode as we call it instead of using the CS32 server.
NOTE: In SAP BusinessObjects Enterprise XI 3.1 (XI 3.1) the Web Intelligence Processing Server was a 32-bit process so it could load this 32-bit BAPI driver natively and fetch data without utilizing a connection server process. We refer to this as loading the driver Inproc or in Library mode.
More details on the history of this can be found in the following KBA:
The latest Data Access Guides also have a chapter (7.11 SAP BW Connections) that talks about his new functionality.
