Yes stefan thanks this solves some of mine problems and brings me near to the goal 
So if you want i can make also an test and can post my results.
So now i have a new question so maybe you can help me with it too 
In my problems it can be, That i have a service that needs a cuple of days to be done. I will make sure for the programm that the services will be split into multiple services with normal workingdays. So for example i have a service in my database that needs 24H so i will cut them into 3*8H services with fitting timewindows.
So my question is: Is there a possibility to make an constraint or an other way to tell the programm that “these 3 services have to be done from the same vehicle”? Because in my context it does not make sence for vehicle1 to begin with service1_1(First cutted service from service1) and service1_2 is done by vehicle2. Its not necessary to have an feature that fixes but it would help me a little bit
thanks for the help till now
