Simulations, on the other hand, allow you to copy an entire budget (or another simulation) and modify the copy without impact. This is useful, for example, if you want to project very different budget assumptions for the coming months/years.
For example, outsourcing, major transformation programmes such as different versions of the ISDS, etc. The simulated elements can then be integrated into the current budget.
All these elements can then be used in all the Finance views to compare them with your current budget :
