In the PROFREAD phase, you enter the DDIC password. It is not usually necessary to change the password of the user DDIC later. After the installation of the shadow system, the password of user DDIC in client 000 is the same as on the original system.

However, if you want to change the password after the PROFREAD phase, you have to change it in the system as well as in the Software Update Manager parameter. The passwords in the original system and in the shadow system have to be identical with the passwords known by the Software Update Manager.
