Downloading BW Master Data into a dBase File 
Use
The first step in the SAPBWKEY maintenance for dynamic geo-characteristics and their geo-coding is to download the BW master data table into a dBase file.
Procedure

If you only want to maintain those entries that have been changed since the last attribute master data upload, choose Geo Data Download (Delta). The geo data has to be downloaded in the delta version before you execute the realignment run for the InfoObject. Otherwise the delta information is lost.

The proposed file name is made up of the technical name of the characteristic and the .dbf extension. You can change the file name and create a directory. If you do not specify a path, the file is save automatically in the SAP work directory.
Result
The status bar contains information on how much data has been transferred.
