Hi Pradeep,
For integrating with GXS, you can go for normal FTP adapter with GenericConverterModule. You can ask GXS for the server details and credentials.
In our case, there were only two folders 'send' and 'receive'. PI have to pick all the files from 'send' folder and place the files in 'receive' folder of GXS.
In addition, we have enhanced the mappings to map with new b2b structure instead of seeburger structure.You also need to use EdiSeparator in case of inbound scenarios.
Regards,
Priya
