Cost Control
You can open, rename, sort, sync, 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 every budget in the project. In it, you open, rename, sort, sync, copy and delete sets. To open it, click **Manage Cost Control Sets** in the set dropdown.
The set dropdown lists the sets of the open budget first and all other sets under **In Other Budgets**. In **Cost Control Sets**, **Root Budgets** on the left lists every budget of the project, and a budget without a cost control set is dimmed. Click a budget to see its sets on the right.
To open a set, click  **Open cost control set** in its row. KOSMA opens the set and closes the dialog. 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, click  **Share…** in its row. KOSMA opens the sharing dialog of the whole budget the set belongs to. See [how sharing works](/kb/article/how-sharing-works).
The help button  next to **New Cost Control** opens KOSMIQ, the assistant in KOSMA. When you point at it, KOSMA shows:
**Message:** Add new cost control set
The button still opens KOSMIQ and does not create a set.
The sets of a budget other than the open one are read-only here. You can open them, but you cannot rename, sort, sync, copy or delete them. With a **Budget** or **Free** licence, you cannot use **Manage Cost Control Sets** outside the demo project: KOSMA closes the dialog and shows a message about your licence. As a guest, you see only the sets others share with you. See [what your licence includes](/kb/article/what-your-licence-includes).
| Column | Shows | | ------------------ | ------------------------------------------------------------------------------------------------------------------------------- | | **Name** | The name of the set | | **Comment** | The comment on the set | | **In this budget** | A dash for every set | | **You can** | What you may do with the set: **Can edit**, **Can view**, **Frozen copy** or **No access**. The project owner always sees **Can edit** | | **Modified** | When the set was last changed |
When you point at the dash in **In this budget**, KOSMA shows:
**Message:** Presence isn't available yet
If you can edit the set, you can change **Name** and **Comment** directly in its row. 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**. Reordering does not change any figure.
KOSMA enables the two sync buttons only when there is something to sync. Click  **Sync cost control set** in a row, or click **Update All**. Both buttons sync the whole file of the open budget with every set stored in it.
Click  in the row of the set. KOSMA opens **Copy Cost Control** for that set. For the next steps, see [copy a cost control set](/kb/article/copy-a-cost-control-set).
Click  **Delete cost control set** in the row of the set. KOSMA asks:
**Message:** 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** to delete the set, or **Cancel** to keep it.
KOSMA locks a budget as long as at least one cost control set is made from it. When you delete its last set, 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).
