How to prevent Account deletion if account has open opportunity ?

Before deleting Account, check for Opportunity associated with it. If Opportunity has stage value - Closed won or Closed Lost, then only we can delete Account otherwise it will throw an error message.

How to achieve this ?

Hi,

Please check the below sample code.

Trigger:
  
trigger AccountDeletion on Account (After delete) {


for(Account a:Trigger.new){

Opportunity opp=new Opportunity();

if(a.id==opp.account.id){

if(opp.StageName=='Closed Won' || opp.StageName=='Closed Lost'){
 delete a;

}
}
else{

a.addError('You cant delete this account');
}

}
}


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

Best Regards,

Hi THUNDER CLOUD,
Use this Code :
  
trigger triggerOnAccountDelete on Account (before delete) {
    list<Opportunity> opp=[select id,accountId,StageName,isClosed from opportunity where accountId in:trigger.old];
    system.debug(opp);
    for(Account a:trigger.old){
        for(Opportunity op:opp){
            if(a.id==op.accountId){
                    if(op.IsClosed==false){
                    system.debug('found');
                    a.addError('You cant delete this account because it have Some Opportunity,StageName-->'+op.StageName);
                }
            }
        }        
    }    
}
