I am trying to achieve this with workflow rule triggering an action, where the previous value is recorded before the edit in another column.
Row[Col] = “First”
Row[Old] = “”
Row[Col] = “Second”
Row[Old] = “First”
Row[Col] = “Third”
Row[Old] = “First,Second”
Workflow[Reaction]: Record Col
Action[Record Col:Do]: Data: sets values in row.
Action[Record Col:Set]: Set Columns: [Old] = [Col]&","&[Old]
I’m thinking the value of [_THISROW_BEFORE] is unavailable to Action?
