Budgetary Control at non-labor resource

Summary:

We have a scenario where an expenditure type is assigned to more than one non-labor resource—for example, both “Computers” and “Computer Equipment” asset categories. A single expenditure type (say, “IT Equipment”) is linked to both. If I create a budget for “Computer Equipment” and enter costs using that shared expenditure type, how does the system determine which non-labor resource it should apply the budget check against?Specifically, I’d like to understand:

1. How does the system distinguish and control budgets across different non-labor resources when they share an expenditure type?
2. Is it necessary to define separate expenditure types for each non-labor resource to enforce budgetary control accurately?
