# Modify running bookings

You can modify specific booking parameters while campaigns are running to adapt to changing market conditions and campaign needs, without compromising pricing stability or campaign integrity.

> [!NOTE]
> Note
> 
> Changing ad-spaces triggers price recalculations and that the booking capacity is re-validated before saving.

You have the following options when modifying your booking:

- **Change ad-spaces**: Modify [ad spaces](/grassfish/docs/create-bookings#specify-ad-spaces) for each booking item during the campaign, with automatic price adjustments.
- **Adjust content distribution**: Update [playbacks, frequency, and Share of Voice](/grassfish/docs/create-bookings#create-a-booking-item) as needed.
- **Adjust end time**: Change the [end time](/grassfish/docs/create-bookings) of each booking item.
