You can define a workbook as the default workbook to use as a template for all your workbooks. The styles, formatting, and the workbook settings that you defined in the default workbook are used when you open a data source. If you save the default workbook on a server, you can share it with other users. If you do not define a default workbook, the data source is opened with the SAP standard settings.
To use a default workbook, go to File→Analysis→Open Data Source. Select a data source and choose OK.

A new workbook with the data from the selected data source is created using the styles, formatting, and workbook settings that you defined in the default workbook.
