Happy to announce that we started the development of building granular trigger for SharePoint item and file changes along with the plan to provide old and new values.
To be able to infer and provide old and new values, we will first need the ability for a trigger that can run when an item is modified and then the ability to get what changed for that modified item. So, to support this, we will be releasing a new trigger and a new action that works along with this new trigger to help you get started.
'When an item or file is modified' trigger
Only triggers on an item or file updates, not on an item or file creation.
'Get item or file properties changes' action
This new action returns information about whether or not a column's value was modified.
This action when released will:
Only work with the 'When an item or file is modified' trigger.
Require versioning to be turned on for the associated list or library
With these two updates, you can now build a flow when someone modifies a list or library and then using the new action check if a particular column or file property was modified since the last flow run. For example, you can check if the Status column was modified since the last run and then get the current Status value, else do something else.
After this update, we will continue to work on enabling the 'Get item or file properties changes' to provide old and new values of the columns.
Thank you all for being patient with us. Will update this thread as we have more updates.
