Reset a signal
Sometimes, signals will need to be reset. For instance, if a signal used to have a value and now is null, the platform will not overwrite the value with a 0 or null.
In order to reset the signal, select the signal. Most of the resets will have to be time dependent. Notice the Gas Production Rate Forecast.

- To reset, change the Signal Type to Static.
 - Save.
 

- Reset the signal back to Time.
 - Save.
 

Notice that the value has no first seen and no last seen value.
- Rerun the workflow to populate the values.
