Hello Mahendra
the way you have mentioned it, this looks more like an authorization issue. Try and compare the User (SU01) with the User whose id is working for the mentioned functionality.
You can also try creating a dummy user in your test environment with exactly same authorization as you user and check the auth failure in Transaction SU53, when you try to chnage the parties invilved in (SAP GUI - crmd_order transaction) if this is auth failure you will come to know the auth object which is failing for this user.
