In the context of a study project, I am looking to create a Gantt view to track the progress of production, delivery, and assembly of my products to determine if the order delivery date is achievable or if I will need to delay my production.

I have already entered all the necessary deadlines in my database, as well as the delivery date announced to a client, but I am unable to link the dates from the different applications or to gather them all in a single Gantt chart.

The goal: to know and display the production launch date for the order based on the delivery date, and the various manufacturing, delivery, supply times, etc.

If someone could help me with this, that would be great because I am a student and I am new to Odoo.
