Hi Sandeep,
As Nitin has said you should share more characteristics about your scenario to help us to think a way that your issue has showed up and if it is possible to suggest any recommendation to the future.
I want to ask you if you are using the option "Archive Faulty Source Files" in your sender file adapter, if you have don't have this option activated the file with error proccessing at adapter level, following this comment yours,
there in Audit log we find the error it is showing that file name error and last message is showing that successful but the file is came to archive directory
it could have been moved to the Archive directory without any processing more rather than to be sent to the receiver system (weird issue because per my understanding only the processed successfully are moved).
Regards.
