In the application it is possible to lock amounts. This means that the amount that you have entered is locked for any changes until you unlock that amount. It is usefull to lock contracted amounts, for example if you have signed the contract with the architect.
By clicking on an amount in the total column of the Costs & Revenue screen, a slide-in opens. To lock an amount, simply click on the checkbox in front of 'Lock amount' (figure 1). Upon activation, you will notice that the input fields and the amounts in the slide-in become disabled. These figures can no longer be edited until the lock is removed.
Figure 1: Locking an amount
If you lock an amount and save it, it will also be visible on the Costs & revenue screen. All objects that are within a group with locked costs will show up in a light grey font (fig. 2). This indicates that the amount is locked and can not be changed. When you click on a locked figure, a pop-up will open stating: 'This value is locked. View details to unlock'. When you click on the link in the pop-up, the slide-in will reopen on which the lock is placed. Now you can unlock the costs if you want to, to enable editing again.

If you would like to lock an amount of a specific group, you need to filter on that group by pressing the filter button in the top right corner of the Costs & revenue screen. The filter will open and you can select the desired group. Save the filter and click on the total column. Now the total amount of the group is shown and can be locked by checking the box in front of 'Lock amount'.
You can lock amounts on the scenario as a whole or on individual groups. It is not possible to place a lock on a random selection (fig. 3).

Some costs or revenues can be used during a goal seek calculation. When those costs or revenues are locked, it is not possible to use these costs or revenues anymore since the goal seek calculation would affect the amount. See goal seek for more information.
