In Salesforce you can automate the update of many field records using workflow rules. We will create two workflow rules:

• Workflow rule  checks the Event booked checkbox and sets the Lead Status to Working – Contacted when the event is scheduled or rescheduled by Customer

To create Workflow rules:

1. Log in to Salesforce.
2. In your Salesforce Setup page, go to Create > Workflow and approvals.
3. Select Workflow rules and click New Rule.
4. From the Object drop-down, select the object to which the rule will apply. In our example, select Lead.
