* Choose the data structure, whose object we are going to create.
* ID of new object
  * Automatic. The unique ID will be created automatically;
  * Manual. You can compose the expression for the ID> For example, it could be todays date, or a combination of other fields (e.g. `$D.md5('{{field1}}' + '{{field2}}')`)  Remember, that length of ID cannot exceed 32 characters. 
* Save ID to the field. Often necessary in case of automatic ID generation.
* Generating an event (see [event model](https://readme.directual.com/scenarios/principles-of-scenarios/directual-event-model)) 

{% hint style="info" %}
If there is an *existing object* with such an ID, no new object will be created. The link to the existing object will be saved to the field.
{% endhint %}
