I have a table which has 'Update Datetime' column. As soon there is a request for work, this column is updated. I can easily create a recursive and keep track of all tasks with updated datetimes (timeline). The problem is that as soon the task is complete, this same column changed and shows the complete task datetime. So I would say column name is distracting here. It is Update Datetime and completed Datetime in same col. I do have a flag which changes when task is complete from 0 to 1. Is there any way, I can capture all updated datetimes before the value changed in that column to complete datetime? I can then create a recursive and keep track of timeline for each task.
