The General tab is where you define general properties for a List. To get to the General tab, double-click on the desired List in the Toolbox (if you haven't added a List you can add if from the 
button in the Toolbox). Then select the General tab.
- Cache Queries If checked, the List will cache parsed queries. This means that if you use the same query multiple times, the query will only be parsed once instead of each time the pull request is made. This can increase simulation run speed, but does require some small memory overhead, depending on how many unique queries are made in a simulation.
- Keep Empty Partitions If checked, the list will never remove partitions, even if they are empty. This is useful if you want to keep statistics on a specific partition. However, depending on how many unique partitions are created on the list, this can use significant amounts of memory.
- Unique Values Only If checked, the List will disallow multiple entries with the same value. If a value is pushed when there is already an entry with that
- Track Number Field Totals If checked, the list will keep statistics on the total (sum) field values of all entries for non-dynamic number fields. This can be used if you want to either listen for changes to a field's total, usually using Process Flow, or if you want to use it to gather model statistical results.
- View Entries... Press View Entries to open list's entry viewer.
- View Back Orders... Press View Back Orders to open list's back order viewer.
- Intial Content The set of controls under Initial Content allow you to define a set of values to be pushed onto the List when the simulation starts. Use the buttons above to add, remove and reorder these values. You can add objects individually, or you can associate the initial content with a model group, so that the List's initial content will always be synced with the objects you specify in the model group.
