I am written one trigger as below it processing certain condition has been stratified then delete the current record.But I am Unable to delete the current record.


Trigger OrderDelete on Company__c (AFTER INSERT,AFTER UPDATE){
 LIST<Company__c> deletecom = NEW LIST<Company__c>();
    FOR(Company__c com : Trigger.new)
        IF((com.Delete__c == TRUE)&&(com.Order_Source_Code__c == 'DUM'))
    IF(deletecom.SIZE() != 0)
        DELETE deletecom;

It throw an exception why I don't no.


Error: Invalid Data. Review all error messages below to correct your data. Apex trigger OrderDelete caused an unexpected exception, contact your administrator: OrderDelete: execution of AfterInsert caused by: System.SObjectException: DML statment cannot operate on trigger.new or trigger.old: Trigger.OrderDelete: line 21, column 1

Some one please help me .....

  • It would be much easier to help you if you provided the exception you are getting. Also, in the for-loop you are adding Company records to the list deleteord, but you are passing list deletecom to the delete operation - use same variable in both cases.

I expect you're receiving this error (including spelling mistake, well done SF):

System.SObjectException: DML statment cannot operate on trigger.new or trigger.old

That's because the record you are trying to delete is in the Trigger.new collection. You would need to re-query the records first:

List<Company__c> companies = [Select Id From Company__c Where Id IN :Trigger.new];

Then, loop companies instead of Trigger.new. The error message is self explanatory.

  • I have been modified my question and added exception also

  • Yes, that is the same error as I describe above. Make the changes I have suggested and everything should be peachy. However, looks like you're trying to delete a record a user has just inserted....thats not going to look nice when the trigger finally does work May 2, 2014 at 7:57
