Ah, I see what you mean now, the change needs to happen on the children and not the parent. 1. On the child object, create a update field value trigger without any timing that changes the value that you need to change. (e.g. change qty to negative) 2. On the parent object, create a "run triggers on related records" trigger without any timing - choose your child object in the picklist. Attach this trigger to your workflow action so it runs only at the time the workflow is pressed (assuming you use a clone workflow action - if you are not, you need to be to use this method). 2.1 If you aren't using a workflow action, you need to create a trigger that iterates through all of your child record and calls runTrigger() on each on them to run the trigger in #1 (i prefer the "run triggers on related records" approach since it is more streamlined and less prone to code issues unlike this one). Hope this helps.
