Hi,

I have an after update trigger and iam getting the below error

System.DmlException: Update failed. First exception on row 0 with id a0zc0000001JnZLAA0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, You are above your limit to select "Pay All" Action: []: Trigger.updateAlertItems: line 47, column 1

How can i get only the red highlighted error message which is a validation rule error message instead of that whole trigger FIELD_CUSTOM_VALIDATION_EXCEPTION error

Below is the trigger

trigger updateAlertItems on Alerts__c (after update) {

Set<ID> ids = Trigger.newMap.keySet();
List<Alerts__c> updatedParents = [SELECT Id, Calculated_Balance__c ,
(SELECT Id, Action__c , Pay_Validation_Rule_Check_1__c , Pay_Validation_Rule_Check_2__c , Pay_Validation_Rule_Check_3__c
from Alert_Items__r ) FROM Alerts__c
WHERE Id in :ids];

List<Alert_Items__c> childrenToUpdate = new List<Alert_Items__c>();

for ( Alerts__c p : updatedParents)
{

if(trigger.oldMap.get(p.id).Action__c!= p.Action__c)
{
system.debug('Enter here 1');
for(Alert_Items__c kid : p.Alert_Items__r)
{

if(p.Action__c == 'Pay All')
{
System.debug('Enter here 2');
kid .Action__c= 'Pay';
}

if(p.Action__c == 'Return All')
{
kid .Action__c= 'Return';

}

childrenToUpdate.add(kid);
}
}
}

if( !childrenToUpdate.isEmpty())
{

System.debug('Enter here 3');
update childrenToUpdate;

}

}

Thanks
