Budgeting
You know when KOSMA saves a budget, what Discard removes and why you cannot edit a budget you opened yourself.
KOSMA saves your budget automatically and uploads each change to the server. With **Discard**, you take the budget back to the last save. If you cannot edit a budget, KOSMA shows you the reason and what you can do.
KOSMA saves about one second after each edit and uploads the change to the server in the same step. While a dialog is open, KOSMA does not save. Your edits in the dialog take effect only when you click **Ok**. **Cancel** undoes them. After a save, you can still undo your edits one by one. To save immediately, choose **Save Project** in the **Project** menu (⌘S, or Ctrl+S on Windows). For what happens offline and when you close a project, see [how your work is saved and synced](/kb/article/how-your-work-is-saved-and-synced).
**Discard** takes every dataset of the project back to the last save, without asking first. You cannot undo it, because KOSMA also clears the undo history of these datasets.
Choose **Discard** in the **Project** menu. Because KOSMA saves about one second after each edit, **Discard** normally removes only the edits of the last second. It does not bring back what **Clear Budget Data** or **Renumber Budget Items** changed, because KOSMA has already saved the result. To undo these commands, see [clear and renumber a budget](/kb/article/clear-and-renumber-a-budget).
In the browser version, the **Save** and **Discard** buttons take the place of the two commands in the **Project** menu. Both are greyed out while there is nothing to save.
If you cannot edit a budget, KOSMA greys out the controls that change it. Point at one of them to see the reason. If you try to edit the budget anyway, KOSMA opens a dialog for that reason (when you are signed out, no dialog opens). In the dataset rail, KOSMA marks the open budget with  or . Click the symbol to open the same dialog.
If someone shared the budget with you, see [how sharing works](/kb/article/how-sharing-works). If you are signed out, see [how your work is saved and synced](/kb/article/how-your-work-is-saved-and-synced).
A budget that is linked to a Cost Control set is locked. KOSMA shows:
This budget is locked because it is linked to a Cost Control set. To make changes, create a copy.
If you try to edit the budget, KOSMA opens **Locked Budget**. The dialog names the linked Cost Control set and offers three buttons:
- **Copy** creates a separate budget that you can edit. - **Unlock for Correction** lets you edit this budget. KOSMA writes your changes directly into the Budget column of the Cost Control set. The forecast you already entered there stays as it is. - **Cancel** closes the dialog, and the budget stays locked.
The unlock lasts until you close the budget. While it lasts, the dataset rail shows  for the budget. Click it to lock the budget again.
With the **Free** licence, you cannot edit a budget, not even in a project you created yourself. Only the Demo Project stays editable. When a trial ends, your licence becomes **Free**. KOSMA shows:
This dataset is locked because your Free licence does not allow editing it. Upgrade your licence — or ask your team admin, if your licence comes from a team.
A paid licence lets you edit only the modules it covers. In a module your licence does not cover, such as Cost Control on a **Budget** licence, KOSMA shows:
You don't have editing access to this module with your licence. Upgrade your licence — or ask your team admin, if your licence comes from a team.
If you try to edit anyway, KOSMA opens the dialog **Upgrade Required** with this message:
Editing a shared dataset needs a paid licence. Your Free licence does not include editing access. Upgrade your licence to continue. If your licence comes from a team, your team admin manages it — ask them to check the team’s plan.
Click **Upgrade** to open the KOSMA pricing page in your browser. For the modules each licence covers, see [what your licence includes](/kb/article/what-your-licence-includes).
While you share editing access to your budget with someone, you cannot edit it yourself. KOSMA shows:
You cannot edit this dataset while editing access is shared. Stop sharing or create a copy.
To edit the budget yourself again, stop sharing it. Or create a copy, which you can edit.
