Cost Control
You know what works differently in cost control than in budgeting, and where you find Timeline, Variables, markups and currencies there.
A cost control set is made from a budget and starts with its accounts, groups and categories. This article lists what works differently from budgeting and where you find the controls you know from there.
In a budget, an account's total is its quantity times its price, plus fringes, extra costs and DFFF. In cost control, a row shows six money columns instead: **Budget**, **Forecast**, **Variance**, **Paid**, **Expected** and **Free**. For what each column means, see [read the six money columns](/kb/article/read-the-six-money-columns). For a negative **Variance**, see [understand a negative variance](/kb/article/understand-a-negative-variance).
Quantity, unit, price, factor and subaccounts are still there, in the account's **Recalculation** tab. A change in **Recalculation** changes only **Forecast**, and **Budget** keeps showing the figure from the budget. For a markup, the tab shows the base, the percentage and the total. For the steps, see [recalculate an account](/kb/article/recalculate-an-account).
When you select an account in the grid, the right panel shows **Account Details**. You can read the values there, but you cannot change them. The one exception is the **Cashflow** panel: click  **Edit cashflow rule** to open **Set Cash Flow Rule** and give the set's own copy of the account a cash flow rule. The budget's rule stays as it is. If the set is locked, **Edit cashflow rule** is disabled. When you select a cost item, the panel shows **Cost Item Details**, where you can edit the item. A cost item has no fringes and no extra costs.
As in budgeting, the top-level rows of the grid are account groups. Categories appear only in the left rail and in the filter panel. The grid ends with the markups, one row for each markup. You change a markup's percentage in the **Recalculation** tab of its row. See [use markups in cost control](/kb/article/use-markups-in-cost-control).
When you create a set, KOSMA locks the budget the set is made from. For what that means, see [how a cost control set relates to a budget](/kb/article/how-a-cost-control-set-relates-to-a-budget).
 **Timeline** is in the left rail, as in budgeting. It opens the set's own timeline. If an account's quantity uses a phase's duration or workdays, a change to that phase there changes the set's **Forecast**. The budget's timeline stays as it is.
The set has its own copy of the variables. To open them, click  **Variables** in the toolbar.
The set has its own currencies. Open the currency settings from the currency selector in the toolbar. If you change an exchange rate there, only the figures of this set change. The budget keeps its rates. See [switch the display currency](/kb/article/switch-the-display-currency).
