When setting up a Line Item (Step 1: Setup), you can choose between two types of objectives: - **Target budget**: the line item delivers until the budget is fully spent. - **Target impressions**: the line item delivers until a defined number of impressions is reached. When selecting a **Target impressions** objective, you still need to set a budget. This budget acts as a limit and safety net — it will never be exceeded. ### When does the line item stop? The line item stops as soon as one of the following conditions is met: - The **end date** is reached - The **impression objective** is reached (even if budget remains) - The **budget** is fully spent (even if the impression objective has not been reached) ### Where to set it up? In **Step 1-Setup:** select **Target impressions** under *Line item objective*, then enter your target number of impressions and set your budget. ![Capture d’écran 2026-05-04 à 09.58.01](https://helpdesk.displayce.com/hs-fs/hubfs/Capture%20d%E2%80%99%C3%A9cran%202026-05-04%20%C3%A0%2009.58.01.png?width=433&height=268&name=Capture%20d%E2%80%99%C3%A9cran%202026-05-04%20%C3%A0%2009.58.01.png) In **Step 5-Summary:** you'll find a reminder of your target impressions alongside the rest of your line item configuration. ![Capture d’écran 2026-05-04 à 10.01.18](https://helpdesk.displayce.com/hs-fs/hubfs/Capture%20d%E2%80%99%C3%A9cran%202026-05-04%20%C3%A0%2010.01.18.png?width=456&height=198&name=Capture%20d%E2%80%99%C3%A9cran%202026-05-04%20%C3%A0%2010.01.18.png) ### How is Automatic Capping is calculated ?   It is based on impression more than budget to ensure smoother spend distribution and prevent the campaign from ending prematurely.  The displayed daily capping is **the minimum value** between the **budget daily capping formula and the impression daily capping formula.** **Daily capping - c**alculated every day at 00:00 (frame local time). Daily capping (budget) = \[remaining budget / remaining days\]  Daily capping (imp) = \[remaining impression / remaining days\] x average CPM /1000 **Hourly capping - re**calculated every hour, within the limit of the daily capping. Hourly capping = \[(daily capping × 110% – spend up to previous hour) / remaining hours in the day\] ### How is it reflected in the Campaign Summary? The **"Line Item Budget"** column has been renamed **"Line Item Target"** to reflect both objective types: - **Target budget** → displays the monetary value - **Target impressions** → displays the target number of impressions If the budget is fully spent before the impression objective is reached, a **tooltip** will appear in the Campaign Summary to flag this situation and suggest increasing the budget. #### Can the impression objective be exceeded? A slight overdelivery may occur. Since impressions are purchased in batches, the line item may deliver a few additional impressions before the system registers that the objective has been reached. The maximum overdelivery is calculated as follows: `Maximum overdelivery = (5 / CPM) × 1,000` **Example:** For a CPM of €10, the maximum overdelivery is 500 impressions. ### FAQ **What happens if the budget is exhausted before reaching the impression target?** \- The line item stops. A tooltip in the Media Buying table flags this situation. Increase the budget to automatically resume the line item. **Is the remaining budget spent if the impression target is reached before the end date?** \- No. The line item stops immediately upon reaching the target, regardless of remaining budget or time. - [Knowledge Base](https://helpdesk.displayce.com/en/knowledge/knowledge-base?hsLang=en#main-content) - [Get started](https://helpdesk.displayce.com/en/knowledge/knowledge-base?hsLang=en#get-started) - [Set up my campaign](https://helpdesk.displayce.com/en/knowledge/knowledge-base?hsLang=en#set-up-my-campaign) - [Set up my Line Item](https://helpdesk.displayce.com/en/knowledge/knowledge-base?hsLang=en#set-up-my-line-item) - [Additional services](https://helpdesk.displayce.com/en/knowledge/knowledge-base?hsLang=en#additional-services) - [Campaign follow-up](https://helpdesk.displayce.com/en/knowledge/knowledge-base?hsLang=en#campaign-follow-up) - [Troubleshooting](https://helpdesk.displayce.com/en/knowledge/knowledge-base?hsLang=en#troubleshooting) - [Inventory](https://helpdesk.displayce.com/en/knowledge/knowledge-base?hsLang=en#inventory) - [Other](https://helpdesk.displayce.com/en/knowledge/knowledge-base?hsLang=en#other) - [New releases](https://helpdesk.displayce.com/en/knowledge/knowledge-base?hsLang=en#new-releases) - [FAQ](https://helpdesk.displayce.com/en/knowledge/faq?hsLang=en#main-content) - [Set-up](https://helpdesk.displayce.com/en/knowledge/faq?hsLang=en#set-up) - [Troubleshooting](https://helpdesk.displayce.com/en/knowledge/faq?hsLang=en#troubleshooting) - [User access](https://helpdesk.displayce.com/en/knowledge/faq?hsLang=en#user-access) [![DSP Dark](https://helpdesk.displayce.com/hs-fs/hubfs/DSP%20Dark.png?width=300&height=53&name=DSP%20Dark.png "DSP Dark")](http://displayce.com) Copyright © 2025, Displayce
