SFTP Receiver Works fine but No file created in SFTP system.

All,

we have noticed there is a serious issue with SFTP receiver communication channel, SFTP receiver log says file is delivered but no file created in SFTP system!!!! is this SAP PI SFTP product bug.

or we presume that the issue could be with module parameters or SFTP adapter , can you please check and advise the solution.

XML2Plain module parameters.
