Cost Control
You can create a cost control set for a budget and decide whether it includes the collect-in accounts of fringes, supplements, extra costs and taxes.
A cost control set is made from a budget and copies its accounts. You need a budget in the project. Creating the set locks the budget you link it to, so finish the budget first. See [how a cost control set relates to a budget](/kb/article/how-a-cost-control-set-relates-to-a-budget).
In Cost Control, click  **New Cost Control**, or choose **Project** > **New Cost Control Set** in the menu bar (Cmd+N on a Mac, Ctrl+N on Windows). KOSMA opens the **New Cost Control** dialog. If the project already has a set in another budget, Cost Control shows the set dropdown, with  **New Cost Control** next to it. In **Cost Control Sets**,  **New Cost Control** opens the dialog too.
If your licence lets you create cost control sets, KOSMA opens a dialog as soon as you open Cost Control. If the project has no set yet, it opens **New Cost Control**. If the project has sets but none for the open budget, it opens **Cost Control Sets** instead (see [manage cost control sets](/kb/article/manage-cost-control-sets)) and shows this message:
**Message:** No cost control set available in the active budget. Add a new cost control set, or select a different budget.
In the demo project, KOSMA opens neither dialog by itself. If you click **Cancel**, Cost Control shows no grid until you create a set, only this message:
**Message:** No cost control set available in this budget
Type a name that says which period or version the set is for, for example "Cost Control Q1". KOSMA suggests **New cost control** and selects it, so what you type replaces it. A comment is optional. While the name field is empty, you cannot click **Create**.
Under **Linked Budget**, choose the budget the set tracks. The list shows every budget of the project. If you opened the dialog in Cost Control or through the menu, KOSMA selects the open budget. A budget that someone else shared with you is greyed out in the list, with this hint:
**Message:** Create a copy to link to it.
**List fringes, supplements and extra costs as cost items** is ticked by default. When the box is ticked, KOSMA copies the collect-in accounts of fringes, supplements, extra costs and taxes into the set like every other account. When it is unticked, KOSMA leaves these accounts out of the set. [How collect-in accounts work](/kb/article/how-collect-in-accounts-work) explains what a collect-in account is.
Neither setting creates cost items.
Click **Create**. While the button shows **Creating…**, you cannot cancel. KOSMA opens the new set. It holds every account of the linked budget, without the collect-in accounts if you unticked the box. At first, **Forecast** equals **Budget** on every account. For which accounts a set shows later, see [which accounts appear in cost control](/kb/article/which-accounts-appear-in-cost-control).
If you will import accounting data later, you can set up the import mapping now; see [set up an import mapping set](/kb/article/set-up-an-import-mapping-set).
**If New Cost Control is greyed out.** Your licence does not let you create cost control sets. You need a Cost Control or Production licence or a running trial. With Budget, you can open and read sets; with Free, only the sets others share with you. See [what your licence includes](/kb/article/what-your-licence-includes).
