Rollback several Streams at once

This method of rollback is generally used when developing – in particular, when building a history over a number of runs, when you have changed the rules for building the history (so you need to start loading your data again from scratch).

Open the model Channel Package Check
Keeping your left mouse button pressed down, drag your cursor over all the streams in your model – it doesn't matter if you include other components
All streams and any other components you included should now be selected
Right click anywhere on the model pane – but on the background, not on any modelling component
From the menu select Rollback Selected Objects
Roll back the streams using the options:
- Rollback all data
- Untick Keep Old Stream Sets
A log entry will be produced telling you what data has been cleared – in this case, all data in all selected components in the model

Rolling back (and re-running) from the Console

This method of rollback is generally used when testing – in particular, when a run was only partially successful, but you have changed the rules in the parts of the model that were successful (so you want to re-load these).

Open the model Channel Package Check
Run the stream Channel List Reconciliation
Open the Console and find the log for the analysis run
Double click on this entry
Go to the Stream Sets tab
You will find two buttons:
- Rollback all data...
- Rollback data and run the analysis again...

Use the button Rollback data and run the analysis again... to repeat the analysis run from the previous exercise.

Rollback a single stream set (a run)

This method of rollback is commonly used when testing a large model. If a single component has been updated and you want to re-run it without causing the rest of the model to re-run, then this approach is suitable.

Open the model Channel Package Check
Right-click on Latest Package Update
Select Rollback
Accept the default options (the Keep Old Stream Sets flag is ticked)
When the rollback has completed, look at the stream set list for this stream – you will see a single stream set (the most recent one) is yellow
Run analysis on this stream
The yellow (incomplete) stream set will be rebuilt – but this run will not cause any of the stream's predecessors to run
