# Edit object step

![](/files/-MVtt1Lk8yuhDroAeilo)

**Edit object** step allows you to edit current object and objects connected with it via links.

{% hint style="info" %}
Remember! You cannot combine **serial actions** with the same field in a single step. You have to create step-by-step chain. It means if you want to increase {{field}} to 5, and then divide it by 10, you should create two separate steps for {{field}} + 5, and then in the second step {{field}} / 10 (don't forget to turn on [evaluating the expression](/template-system/evaluating-as-js-expression.md) for such calculations).
{% endhint %}

## Basic step settings

There can be several fields editing, each includes:

* The field to edit ([select field](/template-system/basics-of-template-system.md#inputs-for-templating));
* The value ([expression](/template-system/basics-of-template-system.md#inputs-for-templating)) – here you can apply JS-interpreter.

## Advanced step settings

### Single-thread execution (lock)

The way to avoid collisions while writing to the same field. 

* Lock key (field type of link like `{{userID}}` or `{{ContextVar.userID}}`);
* Time of lock in milliseconds;
* Global lock option (cross-scenario setting)

### Generation of an event

Following the [event model](/scenarios/principles-of-scenarios/directual-event-model.md), editing an object can trigger other scenarios. By default, this step edits an object in "silence mode", but you can turn on the event generation.
