Do time-dependent workflows verify the rule criteria is still true before executing?

I have a time-dependent workflow on a custom object called ObjA__c that has a lookup to another custom object called ObjB__c. The rule criteria on the workflow is:

ObjA__c.intVal__c = 5 && ObjB__c.intVal__c = 3

The time-dependent workflow action is set to run 1 hour after rule trigger date.

When an ObjA__c record that has an intVal__c != 5 and which is linked to a ObjB__c where the ObjB__c.intVal__c = 3 has it’s intVal__c field update to equal 5 the time-dependent workflow is queued to execute in an hour.

What happens if before the queued workflow executes the ObjB__c.intVal__c is updated to not equal 3?

Since the record being updated is not an ObjA__c record I know that before the execution of the time-dependent workflow the record wouldn’t get removed from the queue. However I am wondering if before executing the action if a check is run to see that (ObjA__c.intVal__c = 5 && ObjB__c.intVal__c = 3) is still true before executing the queued action.


The time-dependent workflow action that this rule executes is a field update.


The criteria is not checked again in this situation – see below

According to the Time-Based Workflow FAQ, any record which no longer matches the criteria for a time-based workflow will be removed from the queue. This is vague though and doesn’t indicate whether a test is performed if the other record is updated.

I would expect that the criteria would work like a formula field, and that the system would at least check for validity when the timer elapses before executing anything, discarding the record in the process – but it seems like I am wrong.

Test Results

I ran a test to see if the criteria would be evaluated again before the workflow actions took place, and it seems like no check is performed.

When changing a field on the second object such that the criteria would not be met, the first record stayed in the queue which is to be expected.

However, the field update I specified was still performed once the time-based rule was processed.

Work Around

If you update the record that’s queued such that it doesn’t meet the criteria for the work flow, it is removed from the queue. An extention of this is that if you modify object B so that A would fail and then perform a non-changing edit on A (i.e. hit edit and then save) it also gets removed on the queue.

The upshot is that you could create a trigger on B after update, to perform a non-changing edit on all child records (object A) of the records being run through the trigger. This should in turn clear out the non-conforming records from the queue and prevent the workflow field updates etc. from taking place.
