Load Scenario

Pull an existing scenario into a workflow so you can analyse it, modify it, or use it as a baseline for comparison.

When to use this

  • You want to re-run an analysis on a scenario you already built, without rebuilding it from raw files
  • You're creating a variant of an existing scenario with a new set of assumptions
  • You're comparing two scenarios and need to bring the baseline into the same workflow as the optimized version

What you need

  • A scenario already saved in this project (via Create Scenario or as the output of a previous run)

Parameters

Parameter Description
Scenario Pick a current scenario from the dropdown. The next run uses its current saved version.

How it works

When a run is accepted, the core resolves the selected scenario to its current saved version, records it, and keeps that exact version while queued and throughout the run. It does not rerun the producing workflow. Existing results and comparisons retain their recorded versions.

Load Scenario emits a full scenario data structure, the same shape that Create Scenario produces. Downstream nodes treat it exactly like a freshly assembled scenario.

Connect the output to compatible analysis nodes from the installed package, or to Create Scenario to save a new named copy. Package nodes declare their input requirements and document how to prepare data for their calculations.

Workflow wiring

Save a named copy of an existing scenario:

Save Data takes rows, not a scenario, so Load Scenario cannot connect to it directly. To export a scenario's rows, pass it through an installed node that turns a scenario into a table.

Common mistakes

  • Confusing a new version with a separate scenario. A producing step updates its own scenario history. Different producing steps can produce Baseline and Baseline (2); check the workflow attribution and the version shown before running.
  • Using a raw-table node to change nested scenario data. Choose a compatible node from the installed package; its ports and documentation describe the accepted input.

Next steps

  • Create Scenario — save scenario data as a named result.
  • Save Data — export rows as a Data Source, after a node that turns the scenario into a table.
  • Browse installed analysis nodes for the calculations available in this deployment.

Messages this node can show

This node has no messages of its own.

A run gives this node 5 minutes. A node that takes longer stops with Time limit reached.

Like every node, it can also stop on the checks before a run and the run's limits.
