Trigger task before insert

Hi All, new to Salesforce Development

I'm trying to create an Apex Trigger in Task(Activity)/Event object.

1) Check a field in Account (Number Field A__c) if more than 100
2) Check a field in Account (Number Field B__c) if more than 50

Basically I have criteria above if not pass, prompt error message to users upon saving their Task/Event record.

Create a trigger before insert and use addError to prompt the error message.

Thanks!

Hi,

I have this code:
  
trigger checkAccount on Task (before insert) {

    for (Task t: Trigger.new)
        {
          if (t.Account.A__c >= 100 && t.Account.B__c <= 50){
            t.addError('Please update your record in Account');
          }
        }
}

Apparently, even the criteria are met, I'm able to create the task. 

Also I did try to pull the information using formula field in Task and upate the code with this, still unable to pass:

if (t.A__c >= 100 && t.B__c <= 50)

Can you add system.debug before the if statement to check the values of those field. And also you should create a Task Handler to store the logic of your code rather than doing it in the trigger itself.

Did you check that your Trigger is Active or Not?

Hi Lokesh,

In the Apex Trigger details, it shows: Status - Active.

Hi,


On Task and events we can not reference cross objects in validation rules:

 

Please find the link below for the article on Idea exchange:

and for workaround, please use below article:

Hi Deepak, 

I'm aware on the limitation using validation rule on this. My validation rule will only run upon saving the Task/Event record.

Seeking help to complete my Apex Code above, having hard time to make it run :(
