# Automatic pause or resume Activations

Objects used in DinMo can be modified or deleted (inside or outside DinMo), affecting activations.

This is the case, for example, when a table used in a DinMo model is deleted from the source data warehouse.

To prevent runs being launched automatically (involving calculations and therefore additional costs at the level of the source), DinMo automatically stops these syncs until the problem has been solved.

#### DinMo's system will automatically pause a activation and its related scheduled ones if:

* If DinMo cannot access the data source
* If a related entity is broken (source, model, calculated field, etc.)

#### On the contrary, DinMo's system will automatically resume a sync and its related scheduled ones if the system has automatically paused a activation (see above) and:

* The source validation is completed without errors
* DinMo no longer detect errors on related entities

{% hint style="info" %}
All verification operations are performed nightly (between 12am and 2am CET) or whenever a user launches a manual test.
{% endhint %}

#### How will the user know if the system has paused the activation?

* On the activation list stopped sync, there is an icon signaling that the activation has an issue.
* A tooltip indicates to the user that the system has automatically paused the activation and indicates what kind of entity is the culprit.
