Activity Budget Header (AC20.7)
Use Activity Budget Header (AC20.7) to define an activity budget header. You can define as many budgets as necessary, but each activity can only have one active budget. For example, if the cost of materials increases, you can define a new active budget by copying the old budget and keeping it for reference while making changes to the new active budget.
The header defines the budget number and description, budget date range, currency and exchange rate information, amount and unit round types, whether it is a life only budget, and whether it is the active budget. You must add the budget header before you can add budget amounts and units.
The active budget displays on AC10.1 (Activity).
