This article describes the following:
When to use the Input Table
Input variables have always allowed you to enter values directly into the model table. With the Input Table feature, you have a richer interface for managing inputs across time. This gives you more flexibility, structure, and options for how values behave in your model.
How it works
Click on a cell in the table for a variable node.
You’ll have two options:
Type directly in the table cell.
Click on the f(t) to open the Input Table to enter structured inputs.
In the Input Table, you can:
Enter values for multiple time steps at once.
Apply a growth rate for a given a period.
Set rules like minimums and maximums.
Combine different input methods for flexibility.
Dynamically leverage historical data for your forecast.
Input Table Features
Starting Period — set the starting time step for a given input value
Starting Value — set the starting value for a given time step
% Growth Rate — specify a % change across time steps
Min/Max Value — set a minimum or maximum constraint
Step-based inputs — define different values at different time steps
Tips
Every variable node has its own Input Table — so you can tailor inputs individually.
You can always switch back to typing directly into the table if that’s faster for one-off changes.
Use Input Tables for scenarios where you’d otherwise have to manually calculate or copy values (like applying a steady growth rate).
Updating Multiple Nodes with Multi-Selection
You can also apply Input Table settings to multiple variables at once.
Select two or more variable nodes in the table.
Open the Input Table.
Any inputs you define will apply to all selected nodes simultaneously.
This is especially useful when you want to apply the same growth pattern, bounds, or step inputs across several variables at once.
