I need to set up project budget control in F&O such that submitted PRs will be rejected if their value takes the project over budget, ignoring the cost centres. Currently I've only been able to get budgets working at a cost centre level of granularity rather than for the whole project as the stakeholders require.
Any help on this would be much appreciated as I'm completely stumped. I've tried using both project management and accounting, and the budget control workspace with custom budget control rules but I've had no success.
