    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,

    If you are using with List then you will Before.trigger to check duplicate then trigger insert data after check.

     

     

    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.
