Cost Control
You can open, rename, sort, copy and delete cost control sets in one dialog, and know when a budget becomes editable again.
The **Cost Control Sets** dialog lists the cost control sets of the budgets in the project. To open it, click **Manage Cost Control Sets** in the set dropdown.
With a **Budget** or **Free** licence, **Manage Cost Control Sets** is greyed out outside the demo project. As a guest, you see sets only if the project owner has ticked **Cost Control** for you in **Project Settings**. You then see only the sets others share with you. See [what your licence includes](/kb/article/what-your-licence-includes).
The set dropdown lists the sets of the open budget first and the sets of other budgets under **In Other Budgets**. In **Cost Control Sets**, **Root Budgets** on the left lists the budgets of the project, and a budget without a cost control set is dimmed. Both lists cover only the budgets that you created or that are shared with you. Click a budget to see its sets on the right.
To open a set, click  **Open cost control set** in its row. To copy a set, click  **Copy Cost Control** in its row; see [copy a cost control set](/kb/article/copy-a-cost-control-set). To create a set, click  **New Cost Control**; see [create a cost control set](/kb/article/create-a-cost-control-set). To share a set, see [how sharing works](/kb/article/how-sharing-works).
The help button  next to **New Cost Control** opens KOSMIQ, the assistant in KOSMA. It does not create a set, although its tooltip reads:
Add new cost control set
The sets of a budget other than the open one are read-only here. You can open them, but you cannot rename, sort, copy or delete them.
| Column | Shows | | --------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Status** | The status of the set: **Final**, **Working**, **Snapshot** or **Archived**. If someone locked the set, a lock  appears beside the status | | **You can** | Your access to the set: **edit** or **view** | | **Last change** | When the set last changed |
To change the status of a set, open the set. At the bottom of the left rail, above **Topsheet Info**, open the **Status** dropdown and choose **Final**, **Working**, **Snapshot** or **Archived**. Below the status, click **Lock** to lock the set or **Unlock** to unlock it. If you can only view the set, the rail shows the status as text.
If you can edit the set, you can change **Name** and **Comment** directly in its row, also when someone has locked the set with **Lock**. The name cannot be empty, and two sets cannot have the same name. To change the order of the list, drag a row by  **Drag to reorder**.
If the set's budget is shared and another person is already editing the set's row, KOSMA closes the cell, discards what you typed and shows who it is:
{name} is editing this row.
If the set's budget is shared, KOSMA also closes the cell when there is no connection to the project.
Click  **Delete cost control set** in the row of the set. KOSMA asks:
Are you sure you want to delete this cost control set?
KOSMA also deletes everything made from the set: a financing plan linked to the set, and the cash flow plans of that financing plan.
Click **Delete**. When you delete the last set of a budget, you can edit the budget again. To change a budget and keep its set, see [how a cost control set relates to a budget](/kb/article/how-a-cost-control-set-relates-to-a-budget).
