Problem

What are some tips for managing models with a large number of scenarios and alternatives?

Solution

In some situations a model may accumulate a large number of scenarios and/or alternatives, for example they are automatically created when using the automated design feature in StormCAD or SewerCAD. You may also have a large number of scenarios created for example for different phases, different "what-if?" situations, etc.

In most cases it is best to clean up the model and remove the old, unneeded scenarios and alternatives to make it easier to work with the model. They can be archived first by simply copying the model to another folder or performing a save-as to another location, then open the original model and perform the clean up. To clean up scenarios and alternatives, delete the scenarios first and then the alternatives using the guidance in the "Deleting Scenarios and Alternatives" section of the article listed in the "See Also" section below.

Other tools for cleaning up scenarios and alternatives (reference # 680491) or being able to search for a scenario label or ID (reference #594754) will be considered for a future version.

Another approach to removing unwanted scenarios and alternatives is by merging them upwards i.e. converting child scenarios into base scenarios. More information on this can be found in the following wiki: Is it possible to make a child scenario/alternative into a base scenario/alternative?
