Please let me know how to update the date field - start date based on the state change of the workitem. As and when the developers change the workitem state from Open to Inprogress, then automatically the start date should be assigned with the date and time. I see the history tab which
provides the preview of the complete workitem changes, in which we also see the state change and the date and time.

Could some one provide me the program to achive the same?

Hi, with 3.x and 4.x you could achieve this using workitem customization. If you create a Java Script based calculated value for that attribute (if it is an attribute that can be set and not only internal to planning). The restriction is that the calculated value provider can only have a dependency to the state, so that only the state change triggers it. See Lab 5 for more examples.

Another option in earlier releases would be - again assuming this is a real attribute of the work item that is stored as any other work item attribute, to create a Java based server participant that detects the state change/action and sets the attribute. See as a starting point.

Note that detecting a state change is very hard in attribute customization. It is necessary to store the current state in an attribute. The calculation can also be triggered multiple times which you have to narrow down to one.
