I have a similar situation. I have a Projects table related to a work_items table (one to many relationship). Work_items have their own start and completed dates that are managed as work is performed. My hope for the Action is to fill in the work_item completed date ONLY for work_items that don't already have completed dates when the parent Project is marked Completed. I have tried setting up the Action but it acts on all work_item children and fills in null work_item completed dates AND overwrites previously recorded work_item completed dates. I need a condition that allows me to choose a subset of the child records. Without this, Actions are too broad to make the edit related option useful.
Thanks in advance to anyone who can help.
