Hi,
While converting lead to opportunity,i want to attach all the attachments from lead to opportunity.
I have written a trigger for this but its nor firing.Can you please help me on this.
  
trigger LeadConvert on Lead (after update) {

List<Attachment> lstattach=new List<Attachment>();



if (Trigger.old[0].isConverted == false && Trigger.new[0].isConverted == true) {


	System.debug('oppid' + Trigger.new[0].ConvertedOpportunityId);
	Attachment aa=[Select Id,ParentId from Attachment where ParentId=:Trigger.new[0].ConvertedaccountId];
	System.debug('attachment in lead' + aa );

if (Trigger.new[0].ConvertedOpportunityId != null) {

for(Attachment a:[Select Id,ParentId from Attachment where ParentId=:Trigger.new[0].ConvertedaccountId]){


  a.ParentId=Trigger.new[0].ConvertedOpportunityId;
  System.debug('parentid' +a.ParentId);

  lstattach.add(a);
}

Hi All,
Thank you for all the replies.
I got the solution.Parent Id is not rewritable so my code was not working.Now i have created a new attachment and inserting it.
Below is the solved code.
  
trigger LeadConvert on Lead (after update) {

if (Trigger.old[0].isConverted == false && Trigger.new[0].isConverted == true) {

// if a new opportunity was created
    System.debug('oppid' + Trigger.new[0].ConvertedOpportunityId);
    

if (Trigger.new[0].ConvertedOpportunityId != null) {

for(Attachment a:[Select Id,ParentId,body,name,ContentType from Attachment where ParentId=:Trigger.new[0].ConvertedaccountId]){

    Attachment attach = new Attachment();
    attach.Body = a.body;
    attach.Name = a.name;
    attach.ParentId = Trigger.new[0].ConvertedOpportunityId;
    attach.IsPrivate = false;
    attach.ContentType=a.ContentType;
    insert attach;
    delete a;  
}
}
}
}

Thanks,
Swaraj

Hi Swaraj,

Use the Before Update context of Trigger, it should work.

Hello Swaraj,

i think we cannot update the attachment parentId and so we need to add the attachment from
Lead to Oppourtunity.

Then delete the Attachment from Lead.

Thanks

Your trigger is wrong, what I can understand is that you want to assign the attachments associated to lead, to the converted opportunity.
Refer the below code: 
trigger LeadConvert on Lead (after update) {
	List<Attachment> lstattach=new List<Attachment>();
	if (Trigger.new[0].isConverted) {
		if (Trigger.new[0].ConvertedOpportunityId != null) {
			for(Attachment a : [Select Id,ParentId from Attachment where ParentId=:Trigger.new[0].Id]){
				a.ParentId=Trigger.new[0].ConvertedOpportunityId;
				System.debug('parentid' +a.ParentId);
				lstattach.add(a);
			}
			update lstattach;
		}
	}
}

trigger LeadConvert on Lead (after update) {

List<Attachment> lstattach=new List<Attachment>();

 // no bulk processing; will only run from the UI
 if (Trigger.new.size() == 1) {

   if (Trigger.old[0].isConverted == false && Trigger.new[0].isConverted == true) {

   // if a new opportunity was created
      if (Trigger.new[0].ConvertedOpportunityId != null) {

   for(Attachment a:[Select Id,ParentId from Attachment where ParentId=:Trigger.new[0].Id]){
      a.ParentId=Trigger.new[0].ConvertedOpportunityId;
      lstattach.add(a);
  }

   update lstattach;
 }
  }
 }

This sample code is not tested but will give you an idea to proceed.
