Only that Booking moves, with its screens and days. Also how to read the Cinema run tab. When a cinema agrees a different week, you change the **Start date** on the Booking. DOS moves that one Booking, and everything that hangs off its date, by the same number of days. This page also shows how to read the **Cinema run** tab, which lists every week a film has played at that cinema. ## Before you start * You need permission to edit Bookings. * Know the exact Booking. A cinema can have several Bookings of the same film, one per language version. Each one has its own date. * A Booking whose invoice is issued, or that already has an imported definitive result, cannot be moved. See "If something looks wrong" below. ## Steps **1. Open the Booking** On **Bookings**, click the Booking row. The Booking panel opens. **2. Start editing the master data** In the header, click the pencil button (its tooltip is **Edit booking master data**). The **Film**, **Cinema** and **Start date** fields become editable. **3. Pick the new date** Choose the new **Start date**. The calendar only enables the first day of a cinema week for that cinema's region: Thursday for D-CH and I-CH, Wednesday for F-CH. If another day gets through, DOS snaps it to the start of that cinema week. **4. Save** Click the save button in the header (its tooltip is **Save master data changes**). To back out, click the cancel button next to it (**Cancel master data changes**). ## What moves, and what does not * The Booking's start and end dates, its screen days, its projection days and its settlement weeks all shift by the same number of days. A week keeps its length and every day keeps its weekday. * Exactly one Booking moves. The other language versions of the same film at the same cinema, in the same week, stay where they are. A date is agreed with a cinema per Booking, not per plan. * The DCP and KDM registers follow the new date. A KDM's validity window and a DCP's delivery date come from the Booking date, so DOS brings both in step in the background. See [KDM and DCP Dispatch](https://wiki.distribution-os.ch/bookings/kdm-and-dcp.md). > [!NOTE] > > If the Booking was generated from a Release Strategy card, it no longer sits on the week that card plans. The card stays the authority over its own plan. A later date change on the card re-dates the Bookings the card owns. ## What you'll see The **Start date** and the **Cinema week** in the Booking header show the new week. The Booking's screens grid and projection days appear on the new dates. ## Read the Cinema run tab Open a saved Booking and click the **Cinema run** tab. It lists every Booking of the film at that cinema, from week one upwards. * The line above the table names the film and the cinema. When the film has other language versions, the **Show Bookings of** switch offers **This version** and **All versions**. * Three tiles sum up the run: **Weeks played**, **Admissions** and **Box office**. Admissions and box office use the official figure, else the provisional one. * Columns are **CW** (cinema week), **Start**, **Condition**, **Adm.**, **Box office CHF** and **Language**. The row for the Booking you have open is highlighted. * A small **P** marks a preview and an **S** marks a special projection or single days. A cancelled Booking shows **Cancelled** and is left out of the totals. * An amber dot next to a figure means the week still has provisional results. The note reads: Provisional results: the official figures for that week are not in yet. ## If something looks wrong > [accordion] Booking N has ..., so its dates can no longer move. Correct it through its own review first. > > The Booking carries an issued invoice or an imported definitive result, and DOS names the reason in the message. Issued invoices are never rewritten by a date move. Correct the invoice through its own review first. See [Invoice statuses](https://wiki.distribution-os.ch/invoices/invoice-statuses.md). > [accordion] The Start date field is greyed out > > The field stays disabled until a cinema is chosen. It shows **Select cinema**. > [accordion] Choose a valid date > > The date was empty or not a real date. Pick it again in the calendar. > [accordion] The Booking you moved still shows the old week in a list > > Reload the list. A colleague's change is picked up live, but your own list can be a moment behind. See [Live updates](https://wiki.distribution-os.ch/get-started/live-updates.md). > [accordion] The DCP Dispatch or KDM row still shows the old date > > DOS updates them after the save. While a film is catching up, those pages show **Updating** and nothing is sent for it. ## Related * [Create a Booking or a special projection](https://wiki.distribution-os.ch/bookings/create-a-booking.md) * [Booking conditions and shares](https://wiki.distribution-os.ch/bookings/conditions-and-shares.md) * [Check a cinema report](https://wiki.distribution-os.ch/results/check-a-cinema-report.md) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
