Cost Control
You can add an account that the budget does not have to a cost control set, and you know why the dialog sometimes offers no reference account.
When you create a cost control set, KOSMA copies every account of its budget into the set. With **Add Account**, you add an account that the budget does not have. The budget stays unchanged.
In the toolbar, click  **Account**. KOSMA opens **Add Account**.
Choose **Above** or **Below**, then choose the reference account in the list: the account that the new one sits next to. KOSMA preselects **Below** and the first account of the list. KOSMA puts the new account directly above or below the reference account, in the same group, so the totals of that group and its category include it.
In the name field, replace New Account with the account's name. In **Account No**, enter a number that no account in the set has yet. As long as either field is empty, **Ok** stays greyed out. If an account in the set already has the number, KOSMA shows this message under **Account No**, and **Ok** stays greyed out:
This account number is already used in this set.
Click **Ok**. KOSMA adds the account to the set and selects it in the grid. **Forecast** shows 0. **Budget** shows 0 too, because the budget has no account with this number. (The column always shows the budget's figure for the same account number.) In the **Recalculation** tab, you cannot change the quantity, unit price or factor of the new account.
To book costs on the account, see [add a cost item by hand](/kb/article/add-a-cost-item-by-hand). In the import mapping set, you choose which account an imported booking goes to; see [set up an import mapping set](/kb/article/set-up-an-import-mapping-set).
Instead of the list, the dialog shows this message, and **Ok** stays greyed out:
No reference account is available yet. Add an account in Budgeting first.
This happens when the set contains no account, for example because you created it from a budget without accounts.
The message's advice does not help here. KOSMA copies the budget's accounts only when it creates the set, so an account you add in Budgeting later never appears in it. The budget is also locked for as long as the set exists.
To work with the accounts of a budget, create a set from a budget that has accounts, see [create a cost control set](/kb/article/create-a-cost-control-set). For how a set and its budget are linked, see [how a cost control set relates to a budget](/kb/article/how-a-cost-control-set-relates-to-a-budget).
