Remaining Early Start of an activity

The Remaining Early Start (RES) is the date the remaining work of a started activity or task resumes.

• In the Masterplan pre-configuration phase, you can set this date if the activity has some progress. You can pick it only until it is saved. It must fall between one working day after the start and the end date.
• When you update an activity's progress in pre-configuration, you must set the RES date.
• Once the RES is set, any later change to it after the Lookahead is generated advances or delays the remaining work of the activity. After the Lookahead exists, the start field itself is labelled Rem. Early Start and you edit it there.

Set the Remaining Early Start

1. Double-click the activity bar to open the edit activity option.
2. Click Edit (the pencil icon).
3. Enter a new Rem. Early Start date based on the activity's progress. The Rem. Early Start and Rem. Duration fields appear for a leaf activity (an activity with no sub activities) when Total Progress is above 0 and below 100.
4. Click Tick.

Rem. Duration is the number of working days of work left from the Rem. Early Start. It is recalculated when you change the progress or the Rem. Early Start. Change it to move the activity's end date.

Note: An activity needs some progress to have a RES date, so edit the RES together with the progress. An activity that is 100% complete has no RES, because no work remains.
