Is it possible with this beautiful tools to o make an automatic planning with automatical implementing of resources? In my Idea all resources are implement in the database with their knowledges (fonctions).
So instead to give the different resources allocated to the project, I will give the knowledges and the programm will give me the name(s).
For exemple, I have 3 Electrician Mr X, Y and Z and I need 1 in one project. The programm will give me one name.

No, not possible.
The programme would not decised which of the three to propose.
It is the work of the project manager to do this (let him work a bit 😉 )

In the allocation of the real work, we have only one value to insert but In reality I can have much more (work overtime, night hours, travel time, ...). With this information, it's possible to make a bills that integrated all informations.

No,these constraints are not taken into account.
But you could possibly manage them using the "function". Instead or managing real function, you could define functions such as "Normal", "Night work", "travel time", ...
Then you could assign one resource for each function. The resource will then see one line of real work allocation for the same task. 😉

Hello babynus,

Thank you for your fast answer. I will try for the second question with your answer.

For the first one, maybe in the futur.
