one feels compelled to ask why you're doing this in the shell...as there is
nothing particularly magical about copying a normal mpe file to a file with
a hfs-name.

anyhow...

i believe the issue is the length of the resulting file name.  here's some
examples:

/SYS/PUB $ ll D2*
-rwxr-xr-x   1 MANAGER.SYS       SYS            0 Aug 29 06:53 D2345678

the above file name is eight characters long.  now to replicate your
command:

/SYS/PUB $ cp D2345678 D2345678_`date +'%Y%m%d%H%M'`
cp: Error copying file D2345678 to D2345678_201308290654:
Implementation-defined  error
/SYS/PUB $

same problem.  the issue is -- hfs-named file that are under a mpe
directory structure (eg, a group) have a limit of 16 characters in the file
name.

let's make a file whose name is four characters long (to skip over 7,6 and
5 :-) and try to redo the copy to see what happens:

/SYS/PUB $ touch d234
/SYS/PUB $ cp d234 d234_`date +'%Y%m%d%H%M'`
cp: target file "d234_201308290655": Filename too long

at least this time the error message makes some sense!

so let's do just three characters:

/SYS/PUB $ touch d23
/SYS/PUB $ cp d23 d23_`date +'%Y%m%d%H%M'`
/SYS/PUB $ ll d23*
-rw-rw----   1 MANAGER.SYS       SYS            0 Aug 29 06:55 d23
-rw-rw----   1 MANAGER.SYS       SYS            0 Aug 29 06:55 d234
-rw-rw----   1 MANAGER.SYS       SYS            0 Aug 29 06:55
d23_201308290655

 ah ha!

so what to do?
1. do the rename as you're doing the put.  you'll need to create a stdin
file for your ftp (but hopefully you're doing this already anyhow).  when
you're making this file, you can do something like:
    echo put bouncerep bouncerep_!hpyyyymmdd>>*mystdin
2. if you have to keep the long-named copy on your mpe box, create a
subdirectory.  the rules for filename lengths change considerably when the
'owning' directory structure is also hfs.
3. shorten the copy-to filename to make the total number of characters be
16 or fewer characters
