# How to use the process tab on a table?

The **Process usage** tab in the **Custom Data model editor** shows whether the table is connected to processes and gives step-by-step guides: write, read, update, and **Ask AI** for block setup.

## When you need this

- The table exists but the bot does not save replies yet.
- You need to find processes using the table before changing fields.
- You want a quick jump to the process builder with table context.

## Key terms

- **Connect to process** — tab title; table hint: **Not connected to a process yet**.
- Blocks: **Write to table**, **Read from table**, **Update record**, **Ask AI**.
- **Open process** — opens the scenario builder.
- **Caution: model is in use** — usage tab lists processes and field references.

## Before you start

- [x] Table is saved with required fields.
- [x] You have a bot and permission to edit processes.

## Step-by-step

1. Open the table → **Edit**.
2. Go to **Process usage**.
3. Read **Caution: model is in use** or **Safe to edit** depending on references.
4. To save replies without code:
   - **Write to table** → **Open process**.
   - In **Text input** or **Keyboard**, enable Save to Custom Data and pick table and field.
5. To read:
   - **Read from table** — add **Actions** → Custom Data find row with conditions.
6. To update:
   - **Update record** — find the row first, then update block with id and fields.
7. Click **Ask AI** in **Ask AI** if you need agent help with blocks.

## What happens next

The process can create, read, and update table rows. The **Not connected to a process yet** hint disappears when usage exists.

## How to verify

- A test dialog saves to the correct field.
- Find block returns a row for your condition.
- The tab lists processes under **Processes** after connection.
