But what if I need production to end at the original planned date even when it is delayed by a shut-down?

To make sure that the volume of the production profile will be produced within a specified end time, when influenced by a shutdown, you will need to alter the PE value for your production profile. On the “Production profile” tab of Forecast Properties, you may set an average PE that is to be applied in the establishment of the production profile.

Then on the “Forecast wells” tab of Forecast Properties, you may override the PE value by setting a specific PE value which will be used with this particular well.
