Trigger Target on Opportunity (before update) |
Take the line update dry and try once
bcos you are writing the code on before update and you dont need again an update dry before the record is being saved

try this
set<id> sup=new set<id>();
for(opportunity opp:trigger.new)
{
sup.add(opp.accountid);
}
list<account>dry = new list<account>();;
Account[]acc=[select id,refereed__c,(select name,amount from opportunities order by amount desc)from account where id in:sup];
for(account lope:acc)
{
for(integer i=0; i<lope.opportunities.size();i++)
{
lope.label__c=lope.opportunities[0].name;
dry.add(lope);
}
}
update dry;
}
u can try this code
Trigger target on Opportunity (before update)
{
set<id> sup=new set<id>();
for(opportunity opp:trigger.new)
{
sup.add(opp.accountid);
}
list<account>dry = new list<account>();
Account[]acc=[select id,(select name,amount from opportunities where amount != null order by amount desc limit 1) from account where id in:sup];
for(account lope:acc)
{
system.debug('lope.opportunities.size()'+lope.opportunities.size()+'opps'+lope.opportunities);
if(lope.opportunities.size() > 0){
system.debug('name'+lope.opportunities[0].name+'amount'+lope.opportunities[0].amount);
lope.previous_rating__c = lope.opportunities[0].name;
//System.debug('The value in the variable of tupoe acocunt is'+lope.refereed__c);
dry.add(lope);
}
}
update dry;
}
Hi Kiran,
When I put update DML statement below is what happens .Any thoughts on this.
Apex trigger target caused an unexpected exception, contact your administrator: target: execution of BeforeUpdate caused by: System.DmlException: Update failed. First exception on row 0 with id 001U0000007uQnvIAE; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, Tiger1: maximum trigger depth exceeded Opportunity trigger event BeforeUpdate for [006U0000004xGer] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv] Account trigger event AfterUpdate for [001U0000007uQnv]: []: Trigger.target: line 20, column 1

Hi Steve,
I also have same understanding of before update trigger.If i take away update statement then it doesn't update my field on the account object..If I put it it kind of runs recursively and give an exception.
So how do I update referred field on the accouint object from opporunitty before update trigger.
Thanks,
Trick
u have a trigger on account object na..? u need to consider than also.. this update will invoke that trigger and the logic inside may lead to recursive loop......so find out that
