How can we prevent duplicate records from being processed by Salesforce trigger?

Hello Anjali,

You can use a Set to store ids, which will prevent duplicate records from being processed.

Example:-

Set<SObject> setIdobject = new Set<SObject>();

for(SObject obj: Trigger.new)

{

setIdSobject.add(obj.id);

}

Thanks.

Hi,

Best way to prevent this is to use Map of Id vs record-

Map<Id, Sobject> mapIdVsRecords = new Map<Id, Sobject>();

for(Sobject sobj : sObjectList){

mapIdVsRecords .put(sobj.Id, sobj);

}

Hope this helps.
