Need help with trigger

Hello,

 

I need assistance in the creation of a trigger that will not allow the deletion of an Opportunity under the following circumstances:

 

  • If there is an Agreement Name (Name) (echosign_dev1__SIGN_Agreement__c is object)
  • Or if there is a Sales Order No (Name) (Sales_Order__c is object)
  • Or if there is an Sales Invoice No (Name) (Sales_Invoice__c is the object)
  • Or if there is an attachment present in the Agreement

 

Thank you for your help.

 

Regards,

Alex

trigger validateChilds on Opportunity (before delete)

    Set<Id> stId = new Set<Id>();
    List<echosign_dev1__SIGN_Agreement__c> lstRe =[Select Id, Opportunity__c from echosign_dev1__SIGN_Agreement__c where opportunity__c in : Trigger.oldMap.KeySet() ];

        if(stId.contains(objA.Id))
        {
     	   objA.addError('you can not delete this, As there are AGreements available .');
           return;
        }

	if(stIdS.contains(objA.Id))
        {
     	   objA.addError('you can not delete this, As there are some Sales Order available .');
           return;
        }

	if(stIdSI.contains(objA.Id))
        {
     	   objA.addError('you can not delete this, As there are some sales INvoice available');
           return;
        }

	if(stIdAtt.contains(objA.Id))
        {
     	   objA.addError('you can not delete this, As there are some Google docs are attached to it ');
           return;
        }

    }
}

Hello, Alex,

 

This sounds like pretty serious development you want done.  You'll probably get better help by securing a small budget and posting the job on a site like Elance.

Hi Alex,

 

trigger deleteTest on Opportunity (before delete) {

    Set<id> agreeAttachment = new set<id>();

    for(Attachment a : [select id, name, parentid from Attachment]){
        agreeAttachment.add(a.ParentId);
    }

    for (Opportunity opp : trigger.old){
        //Assuming that the name of the loop-up fields on the Opportunity are as echosign_dev1__SIGN_Agreement__c, Sales_Order__c and Sales_Invoice__c
        if(opp.echosign_dev1__SIGN_Agreement__c != null || opp.Sales_Order__c != null || opp.Sales_Invoice__c!=null ||  agreeAttachment.contains(opp.echosign_dev1__SIGN_Agreement__c)){
            opp.addError('enter your error message here!!');
        }
    }
}

Hope this helps!

Above script will work for bulk as well.

Hello bForce,

 

I really appreciate your help.  There was only a minor problem.  I had to change Opportunity__c to echosign_dev1__Opportunity__c since that is how the Opportunity is referenced within the Agreement. 

 

The trigger saved just fine so now I just have to test things out.  Two thumbs up!!!

 

Regards,
