If you are trying to copy your central objects from one pathcode to another, you can use the R98403. Also run the R98403 and have it update the F983051, do not overwrite it, only have it append. Also, run the R989861 to copy your Object Librarian entries.
Are you trying to create a whole new pathocde/environment, or are you just trying to update an existing environment?
I hope this helps.
