Execute a SOQL query for Amount, Probability, Stage, and Close Date on the Opportunity History object. Create a custom date field on Opportunity for each field to track the previous date and execute a SOQL query for date fields. Subscribe to the OpportunityHistory Change Data Capture event in the Lightning component. Subscribe to the Opportunity Change Data Capture event in the Lightning component. None Users upload .csv files in an external system to create account and contact records in Salesforce. Up to 200 records can be created at a time.

Modify the trigger to use the isMultithread=crue annotation. None A developer is tasked with creating a Lightning web component that allows users to create a Case for a selected product, directly from a custom Lightning page. The input fields in the component are displayed in a non-linear fashion on top of an image of the product to help the user better understand the meaning of the fields.
