+## Introduction
+
+The **Cancel synchronization** activity cancels a running synchronization. You can trigger another synchronization later. For more information on the synchronization behavior, see [Synchronize](/refguide/mobile/building-efficient-mobile-apps/offlinefirst-data/synchronization/).
+
+## Properties
+
+There are two sets of properties for this activity, those in the dialog box on the left, and those in the properties pane on the right:
+
+{{< figure src="/attachments/refguide/modeling/application-logic/microflows-and-nanoflows/activities/client-activities/cancel-synchronization/cancel-synchronization-properties.png" >}}
+
+The **Cancel synchronization** properties pane consists of the following sections:
+
+* [Action](#action)
+* [Common](#common)
+
+## Action Section {#action}
+
+The **Action** section of the properties pane shows the action associated with this activity. It defines what happens when the **Cancel synchronization** activity is executed and specifies that the running synchronization process will be cancelled.
+
+## Common Section {#common}
+
+{{% snippet file="/static/_includes/refguide/microflow-common-section-link.md" %}}
+
+## Limitations
+
+* If the synchronization is in a step that applies file-related changes, it is not canceled to avoid leaving the system in an inconsistent state.
+* If the synchronization is already in its final steps, cancellation is not applied because most of the processing is already complete. The process is therefore allowed to finish.
