Running File Mode Sessions

Running File Mode Sessions

You can run PowerExchange for SAP NetWeaver sessions in file mode when the dataset is large.
To run a session in file mode, select the SAP Staging Reader as the source reader type in the session properties. Select SAP Staging Reader if you installed an ABAP program in the Mapping Designer, and you selected file mode when you generated the ABAP program.
If you have separate application connections for file and stream modes, select the application connection that is configured to connect to the SAP system using RFC.
When you run a file mode session, the installed ABAP program creates a staging file on the application server. The program extracts source data and loads it into the file. The PowerCenter Integration Service process is idle while the program extracts data and loads the file. When the file is complete, the PowerCenter Integration Service accesses the file and continues processing the session. The ABAP program then deletes the staging file unless you configure the session to reuse the file.
File mode sessions do not require an online connection between the PowerCenter Integration Service and SAP while the generated ABAP program is extracting data. For this reason, you can run a file mode session offline using a background process. Choose background processing when the data volume is high and the extraction time exceeds the limit for dialog processes.
