transport request problem

hi all,

my requirement is to do changes in the code that is coded by some third party developer.

after doing the changes when i try to create a request, the request that get created is a local change request-which don't get transported to the production system(i think so..)

when i checked the attributes of the program , the original system field is not the development system of our organisation,but something else...can this could be the reason....if so then how to do the changes in the object directory entry....
