Problem copying Request with CopyUtility

Hello,

I need to copy a request artifact from a project area to another, in order to be able to assign a reservation from the destination project.
I have used CopyUtility with the following command:

java -jar RQMCopyUtility.jar -s=<source_address> -d=<destination_address> -us=<user_source> -pws=<password_<source> -ud=<user_destination> -pwd=<password_destination> -a=request -id=<request_id>

Now, everything works apparently fine and the request is actually copied into the destination project area, and even values appear to be correct.
But when I try to assign a reservation to that request I receive the error:

Validation errors for item: type = Reservation, itemId = Required property must not be null: reservedFor

Checking the values in the RQM database I see that the field "RECIPIENT_ITEM_ID" of the copied request is null.

Can anyone tell me why does RQMCopyUtility act this way or, at least, how to correctly copy the request so that I can use it as it's supposed to be used?
