By planning, at the first level, we have to associate start date and duration to each topic (not only the ressources or activities), and then be able to see the topic in a calendar.
In a second step, it will be required to book for other materials to be used during the topic execution.
After a few search, I have not found extensions that are answering this need.
What would you recommend to achieve this requirement (as much as possible) ?
Thank you for your help.
