I would like to know if the behaviour on your system gives identical results:
* add a new operation to a production order; choose one of your tasks with task type 'Machine'; the man/machine ratio should be set to 1.0. Lets say we take a Nr of Resource Units of 2.0.
* After that, have a look at ticst002. You should see a new record containing your production order, operation and a sequence number of 0 (i.e. estimated hours and costs).
* I think you will see both Man hours = 2 and Machine hours = 2 (both get Nr of Resource Units).

And that's my problem. I think that we had some time ago a different behaviour with Man hours = 0 and Machine hours = 2.

As far as I know, baan calculates the operation hours as sum of man hours and machine hours, which would result in 4 hours (instead of the 2 hours I entered).
I see this e.g. in the session tipcs3462m000 print actual cost price by project (production order of above linked to a project).

Can anybody explain me that, please?
