delivery method - Primary FTP

I am using partner’s delivery method as Primary FTP to ftp a large document. it is doing the FTP successfully but the file name is some bizdoc id and not the remoteFileName defined in Document type in TN. In TN transactionanalysis, I can see the RemoteFileName appearing correctly but when i check in ftp, the actual file name is bizdocid. any help on what is going wrong? Thanks

There isn’t a way to control the filename of the file when using the provided FTP delivery method. To control that, you’ll need to create a custom delivery method.
