When doing a outgoing SFTP transfer (as client), the transfer is rejected because of the following erreor :
SFTP103I  20.01.2010  17:28:01  FRC2XI12(Read) ID:1 SSH_FXP_STATUS code:3.
SFTP010E  20.01.2010  17:28:01  FRC2XI12(28)      ABORT received : 0 147.
(permission denied)

In the FT_SFTP.out , there are these lines:
-- 2010/01/20 17:28:01 - ERROR from SftpCliStatus
  2010/01/20 17:28:01   Cannot open remote file : permission denied!
  2010/01/20 17:28:01   Error code : 3 message : [2010/01/20 17:29:26.342] SSE2636 Command rejected due to sftp proxy policy settings: SSH_FXP_OPEN

What do these messages mean?

The command SSH_FXP_OPEN sent by clien (Gateway) was rejected by the partner with error code 3. According to SFTP protocol, error code 3 means "SSH_FX_PERMISSION_DENIED:       The user does not have sufficient permissions to perform the operation". The detailed error message "Command rejected due to sftp proxy policy settings: SSH_FXP_OPEN".
was made and sent by the partner, Gateway just logs it in the .out.  There is no explaination about this message in SFTP rfc.

To know exact cause, the question has to be asked to the partner:
- why it refuses the SSH_FXP_OPEN
- what does it mean exactly "Command rejected due to sftp proxy policy settings"
