You can configure AS2 inbound transfers to move and/or rename files after they are received. These settings, combined with setting Duplicate Contents with different Message ID to Reject will prevent received files of the same name and extension from being overwritten.
To rename received files
In the Administrator, connect to EFT Server and click the Server tab.
In the left pane, click the user (trading partner) you want to configure.
In the right pane, click the Connections tab.
Click AS2 Inbound. The AS2 Inbound Settings dialog box appears.
In the Rename file(s)
to box, click in the far right to activate the text box, then provide
the characters and/or variables with which to change the name of received
files. Use %EVENT.DATESTAMP%
to add the date and time to the file name. Use %FS.FILE_NAME%
for the name of the file.
For example, if you type:
A file transferred as dailyprogress.doc on May 3, 2008 at 10:56:26 would be renamed to 05032008_105626_dailyprogress.doc.
Click OK to close the AS2 Inbound Settings dialog box.
Click Apply to save the changes on EFT Server.
