Hi, You should really do a conceptional workshop first, then admin training, followed by ChangeBuilder training: http://www.otrs.com/solutions/services/consulting/ and http://www.otrs.com/solutions/services/training/
Do you have any example of a minimal conditions I must have to make the change state work correctly?
No, as every Change is different and Standard Changes are company specific.
Does the order of the conditions matter?
Yes
I've created an approval workorder and approved it as you said, but the state of the change still is "Created", am I missing something?
No
When the state changes to pending approval? or accepted?
If conditions match
I've added a agent in the CAB, shouldn't it create a approval workorder to this agent automatically?
No
I've added a agent in the CAB, shouldn't it send an e-mail to the ones in the CAB?
Based on your notification configuration
I couldn't link a change to a CI only to tickets. How may I do that?
Use workorders
How does a user approves or rejects a change?
Up to your Change process
How does otrs works with Change Management?
very well ;-) -- Cheers, Nils http://webint.cryptonode.de / a Fractal project
