Need help on Bulk Trigger to add Opportunity Line Items

Hi I have written a Apex trigger for inserting opportunity line items and it is working fine. But the only issue is I am not able to insert more than 15 records in one shot. Please Help me!!

 

The code is as below:

 

trigger OppportunityProductInsert on Opportunity (after Insert, after Update ) {

Integer Num =1;
For (Integer I = 0; I < Num; I++)
For (Opportunity a : Trigger.new)
if (a.RecordTypeId=='01290000000UUr2' && (a.Number_of_Resources__c-a.Total_Number_of_Opportunity_Products__c)>0)
{
Product2 Prod = [select Id from Product2 limit 1 ];
Pricebook2 PB = [select Id from Pricebook2 where IsActive=True  limit 1 ];
PricebookEntry P = [select Id from PricebookEntry where CurrencyIsoCode=:a.CurrencyIsoCode And Pricebook2Id=:PB.Id limit 1 ]; 
OpportunityLineItem OppLI = new OpportunityLineItem (OpportunityId=a.id, UnitPrice=0, Quantity =1, PricebookEntryId=P.Id);
Insert OppLI;
}
}

You need to bulkify your trigger

 

here is a link to a good article on the topic: Writing Bulk Triggers for Salesforce.com

Thanks for the Link. But I could not find a solutions out of it even after trying for several times. If you can help me through the code where exactly the changes has to happen, that might help me in solving this issue of writing bulk trigger.

 

Since I am new to coding and development, I need more help towards this.

You've got two problems that I see. The insert statment within the For loop and the three SOQL queries in the For loop. As a general rule, you should never have DML operations or SOQL queries inside of a loop. I also don't see you using the Product that you retrieve with the first query.

 

To bulkify, you need to move your queries and DML statement outside the loop. Typically you would do this by collecting the data you need to query on in a list or set, then performing your query, then loop through the appropriate records again to do something to them and add to another list that you'll use for the DML statement.

 

I'm not sure what you're really trying to accomplish with the queries within you loop, so I won't try to rewrite it for you. It should be a pretty simple one to write, but I'm confused by those queries....

Hi Sunay,

 

You have not optimized your trigger to save limits.Using dml statement (Insert OppLI; in your case) and SOQL in LOOP is not the right way of writing triggers.

You should write your triggerd using collections like this

 

trigger OppportunityProductInsert on Opportunity (after Insert, after Update ) {

/* Seems of no use to me , please remove if not needed
Integer Num =1;
For (Integer I = 0; I < Num; I++)
*/
Product2 Prod = [select Id from Product2 limit 1 ];
Pricebook2 PB = [select Id from Pricebook2 where IsActive=True  limit 1 ];
PricebookEntry P = [select Id from PricebookEntry where CurrencyIsoCode=:a.CurrencyIsoCode And Pricebook2Id=:PB.Id limit 1 ]; 
List<OpportunityLineItem> listOfOppLI = new List<OpportunityLineItem>();
For (Opportunity a : Trigger.new)
if (a.RecordTypeId=='01290000000UUr2' && (a.Number_of_Resources__c-a.Total_Number_of_Opportunity_Products__c)>0)
{
OpportunityLineItem OppLI = new OpportunityLineItem (OpportunityId=a.id, UnitPrice=0, Quantity =1, PricebookEntryId=P.Id);
listOfOppLI.add(OppLI );
}
Insert listOfOppLI;
}

Hi David,

 

Thanks for your response!!

 

Let me explain to you about the trigger in detail:

 

When a new opportunity is created for a record type 'T&M', we will be entering the number of resources required in a field called 'Number of Resources'. When the record is saved, based on the number of resources, the opportunity line items should get inserted automatically which is editable.

 

Also when the opportunity record is edited or updated, the line items should get inserted based on the number of resources.

 

This is what we are trying to achieve, and we were successful with the above code for a limit of 15 resources. Suppose I give as '16 or more' while inserting or add '16 or more ' while updating, the above mentioned error shows up.

 

I hope this can help you in understanding the requirement and will be able to help me on this.

Do you hae any trigger on OpportunityLineItem or any field update using workflow rule.
SunaySunay

Hi,

 

Thanks for the reply!!

 

Ya we have triggers on Opportunity Line item to update another custom object called "Forecasts". Also we have workflow rules on the Opportunity Line item.

Here is your problem one trigger of yours calls another then I am sure you are going deeper in triggers calling trigger. You need to use static variable in this case to stop excecution of  some triggers.

 

Please check this : http://forceschool.blogspot.com/2011/05/writing-apex-trigger-issues-and_24.html

 

Even though your case is not of bulk upload as given in example ut you can use similar approach by using static variable.

Set this static variable to false before you update opportunityLineItem records in this trigger.

Hi,

 

Since I am new to coding. Can  you please help me on the above code which is posted. I am confused on the coding part.

Create a class

 

 

public class Constants  
    {  
         //Constant to block execution of trigger  
         public static Boolean runTrigger = true;  
    }

 In your trigger in OppLine item

 

triggert on OpportunityLineItem(before insert , before update)
{
         if(Constants.runTrigger)
          {
               //Put Your logic that you have for trigger to execute in this condition
          }
}

 

 

 

In your trigger

 

 

OpportunityLineItem OppLI = new OpportunityLineItem (OpportunityId=a.id, UnitPrice=0, Quantity =1, PricebookEntryId=P.Id);
//Set static variable to false
Constants.runTrigger = false;
Insert OppLI;

 

I hope it will work for you.

Hi Shashikant,

 

I tried the above, but whenever I insert or update, only one record is getting created. How do I create more number of records???

 

Please help!!

Sunay
Shashikant SharmaShashikant Sharma

I did not get your question, because how many number of OppLineItem gets created depends on your trigger which seems to me is not correct. I have provided some acrticles on Apex Trigger including bulk trigger handlin please check them.
