Liubov Korneva Opportunity Trigger Before Update doesn't work
So here is the scenario, I want to have an error message when user click Save after he changes Opportunity Stage from 10% Probability to 20% probability. I am using Related list Object Contact Role so not sure if this is what causing the issue
trigger ContactValidate on Opportunity ( before update ) {
Set<ID> oppId = new Set<ID>();
for(Opportunity o : trigger.new){
if(o.StageName != Trigger.oldMap.get(o.Id).StageName){
oppId.add(o.Id);
}
}
//If(oppId!=null){
If(!oppId.IsEmpty()){
List<OpportunityContactRole> OCR = [select id from OpportunityContactRole where OpportunityId=:oppId];
if( OCR.size()==0 ){
for(Opportunity o : trigger.new){
if(o.Probability == 10){
o.addError('No Contact associated with opportunity');
}
}
}
}
}
trigger ContactValidate on Opportunity ( before update ) {
Set<ID> oppId = new Set<ID>();
for(Opportunity o : trigger.new){
if(o.StageName != Trigger.oldMap.get(o.Id).StageName){
oppId.add(o.Id);
}
}
//If(oppId!=null){
If(!oppId.IsEmpty()){
List<OpportunityContactRole> OCR = [select id from OpportunityContactRole where OpportunityId=:oppId];
if( OCR.size()==0 ){
for(Opportunity o : trigger.new){
if(o.Probability == 10){
o.addError('No Contact associated with opportunity');
}
}
}
}
}
change this line
List<OpportunityContactRole> OCR = [select id from OpportunityContactRole where OpportunityId=:oppId];
with this
List<OpportunityContactRole> OCR = [select id from OpportunityContactRole where OpportunityId in :oppId];
Hope this helps...
i am new to coding.
may i know what is the purpose of keeping this statement in the above program. Set<ID> oppId = new Set<ID>();
Thanking you in Advance,,
Set<ID> oppId = new Set<ID>();
It is a collection of unique IDs you are collecting in the loop. You are initializing this variable here first.
for(Opportunity o : trigger.new){
if(o.StageName != Trigger.oldMap.get(o.Id).StageName){
oppId.add(o.Id);
}
I hope its clarify your question.
