I need to keep two lists in the same site in synchrony.
Therefor I need to prevent people from updating an item in one list while the item is being updated or while a workflow is running.
I thought I could use NW action "Set approval status" but this can only be used with the current item.
The idea was to set the items approval status to "Pending" in both lists as long as the item is being updated or the workflow running on either of both lists.
Any suggestions how to achieve this?
Additional note: we are still using SP2010 and REST API is not available.
