Change Object Listener Nav web service

Hi All

I have written a function in codeunit 50001 and published it on web service if I go to look web service function on internet explorer (http://localhost:7047/….) it is working fine.

Now if I add new function on same codeunit I can’t see that funciton on (http://localhost:7047/….)

Now if I copy this codeunit and save it with anothet ID say 50002 then I can see new funciton as well but same happen again with this codeunit. so it means there is nothing wrong with function.

I have domain/admin user on Nav server as well as on $ndo$navlistener.

can some one help me why it is happening.
