It would be nice to have a trigger if a certain column in a SharePoint list is modified. For example, if the column "Status" is modified, or if the column "Assigned To" is populated. So we don't have to use the trigger "When an item is created or modified", where you have to create a lot of workaround conditions just to make sure that the column that was updated is what you need.
Happy to say we are planing to start this work in April.
The first deliverable will be a new action that will get changes for one or more columns in a list or library using versions. The action will not only return the columns changed but also all values for each column since the last time the flow ran, thus bringing support for new and old values. You will be able to use this action in your existing flows with the 'when items are created or modified' trigger and still get to know what columns changed and their values.
The second deliverable will be a new trigger 'When a column value changes in a list or library'. This requires more development time. However, we believe the new action will be sufficient for all scenarios and also helps to close this idea as well.
Can't wait for this to land! Let us know what you think!
