Hi Nagarjuna,

try with below code 
trigger  leadUpdate on Lead (before update) {
if(trigger.isBefore && trigger.isUpdate){
         for(Lead l :trigger.new){
        if(trigger.oldMap.get(l.id).LeadSource != l.LeadSource && l.LeadSource == 'Direct'){
           l.LeadStatus = 'Hot';
        }
    
    }
   
    
    }
}

If this helps, Please mark it as best answer.

Thanks!!

Hi Nagarajun,

Before triggers are used to perform the logic on the same object and it triggers fired before the data saved into the database. For DML operation it required to commit with data base. So, we cannot use the DML operation on these triggers.
  
trigger  leadUpdateTrigger on Lead (before update) {
if(trigger.isBefore && trigger.isUpdate){
         for(Lead led :trigger.new){
        if(trigger.oldMap.get(led.id).LeadSource != led.LeadSource && led.LeadSource == 'Direct'){
           led.LeadStatus = 'Hot';
        }
    
    } 
    
    }
}


if you need any assistanse, Please let me know!!

Kindly mark my solution as the best answer if it helps you.

Thanks

Hi, Write a trigger on lead such that whenever leadSource is 'Direct' then leadStatus is equal to 'Hot'. Indeed a trigger for that. Thanks in Advance

Hi Nagarjuna,

Instead of triiger you can use WorkFlow or Process buider, for your solution

Hi  Nagarjuna,
please find answers to your query below.
1.  
trigger  leadUpdate on Lead (before update) {
if(trigger.isBefore && trigger.isUpdate){
         for(Lead l :trigger.new){
        if(trigger.oldMap.get(l.id).LeadSource != l.LeadSource && l.LeadSource == 'Direct'){
           l.LeadStatus = 'Hot';
        }
    }
   }
}
2. You cannot  perform DML operation In trigger, the reason it is not possible is 
  • In Before trigger If you update any  value in the record  salesforce automatically update the value for you, DML Statements are not required  in code 
  • In after trigger, the record in which the update is happing is locked so you are not allowed to perform any DML here. 
Kindly mark my solution as the best answer if it helps you.
Thanks
