As you all know the import of a table via csv file is easy and straightforward in SAP HANA Studio (see e.g. http://www.saphana.com/docs/DOC-2191 from SAP HANA Academy).
The export of a table from SAP Netweaver to a csv file is unfortunately not so straightforward. Therefore I wrote a little ABAP program which simplifies the table export as csv file. This is a screenshot of the selection screen:
You can specify the table and the csv filename. Furthermore you have the following options:
Here comes the source code. Please drop me a little comment below, if the program could help you.
