Issue while archiving the processed file in sender communication channel using SFTP adapter

Hi All,

In one of my scenario (File to IDOC), we are using SFTP sender communicationchannel.

we are facing an issue while archiving the processed file. Some times PI processed the file successfully but unable to archive it and in the next poll PI process & archives the same file successfully which will creates duplicate orders in ECC.

Please let us know how to resolve this issue.
