File(NFS) to SFTP Large File transfer and No Mapping

[Muniyappan]

Hi All,

I have to transfer large size files from AL11 to SFTP folder. File type is text. The size can be between 3 gb and 4 gb.

I was thinking to use File chunk option to transfer the files to SFTP.

https://blogs.sap.com/2010/10/18/pixi-pi-73-processing-of-large-files-teaser/

But as per SAP note 1783846, File adpter chunking option can be used with only File to File scenario.

I gave a try chunk mode for this File to SFTP scenario. But getting error in SFTP server.

i tried parameter in SFTP receiver "skipRemoteDirCheck true", but no luck, still same error. only first chunk is getting delivered to SFTP and rest are getting failed with below error.

Did anyone work on this kind of scenario, will file adpter file chunk option work with SFTP receiver?

Any other suggestion to handle this scenario.

Regards,
