How to create a flat file to export (WBTE) site data (WB01/WB02)

Hi,

I created site by using transaction WB01with customer and Vendor. Now I am trying to save this data as a flat file by opening the trasaction WB02.

I followed the below process while transporting Site from one system to another.

To get a flat file I tried below path

WB02 - Opended the site --> System --> from dropdown options "List" --> SAVE --> Next options are in disable mode to save the file.

Please confirm the process I am following is correct, if not let me know the right process to save the site data as a flat file.

Thanks&Regards,
