How to Lock the Case  Record when it contains open Tasks i.e. task Status = open

Hi,

We have a Batch class which is scheduled to run every day. This batch will update a specific user with role to a custom field on Oppty.

The problem is that we have a Validation rule on Oppty, because of which some Batches are failing.

I want to bypass this validation rule while the Batch job is running.

Is the below code snippet correct?

*************************************************************************************************************************************

 try{    
      update opp; //This is the Oppty which we are updating
      }
     
      Catch(Exception e)
      {
         string sErrMsg=e.getmessage();
       if(sErrMsg.contains('Opportunities can only be created for active Prospects/Customers.You are unable to create this opportunity because either your prospect has not been approved yet or Prospect/Customer record is inactive--which will require onboarding the Prospect/Customer.'))
           return;
      }

*************************************************************************************************************************************

will this piece of code bypass the validation rule and will this help the batches to run successfully?
