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. The set has its own copy of each account. 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. 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.
Variables are shared by the budget and every set made from it. To open the variables, click  **Variables** in the toolbar.
The set has its own currencies. If you change an exchange rate in the currency settings, which you open from the currency selector in the toolbar, only the figures of this set change. The budget keeps its rates. See [switch the display currency](/kb/article/switch-the-display-currency).
