Hi Deepankar,
You might getting the error message as you have selected the "Complete" option under Detail Log in the variant.
If you re run the archiving without moving the archiving session to invalid, it creates the duplicate archive file. Suggest to move the incomplete archiving sessions to invalid state, if the deletion is not yet happened. You can re run the FI_DOCUMNT archiving again. To remove the invalid archiving sessions request to run the archiving again with BC_ARCHIVE.
Regards,
Sudheer T
