Upon Opportunity Creation if Amount is not null and is greater than 100000 then populate ‘Hot Opportunity’ in description field triggers in Salesforce

 Here’s an Apex Trigger that sets the Description field on an Opportunity to Hot Opportunity when the Amount is not null and greater than 100,000 during Opportunity creation.

trigger SetDescriptionForHotOpportunity on Opportunity (before insert) {

    for (Opportunity opp : Trigger.new) {

        // Check if Amount is not null and greater than 100,000

        if (opp.Amount != null && opp.Amount > 100000) {

            opp.Description = 'Hot Opportunity';

        }

    }

}

Explanation of the Code

1. Trigger Event:

   • The trigger is written for the before insert event since the Description field needs to be populated before the record is saved.

2. Logic:

   • Checks if the Amount field is not null and greater than 100,000.
   • If the condition is true, the Description field is set to 'Hot Opportunity'.

3. Bulk Processing:

• The trigger iterates over all records in Trigger.new to ensure it works for bulk inserts.
