When can you update a scenario with changes from its parent?

The ability to update a scenario with changes from its parent is contingent upon modifications being made to the parent scenario. This reflects the hierarchical relationship where the parent serves as the baseline or reference point for scenarios that branch off from it. When the parent has changes, it indicates that there are new data or configuration adjustments which can potentially affect the child scenario. Hence, it is logical to incorporate these adjustments into the child scenario to ensure consistency and relevancy of data.

When the parent has been modified, the changes may include new parameter values, updated constraints, or any alterations that affect the overall scenario planning. This provides an opportunity for users to refresh their scenarios and leverage the most current and relevant data available, improving decision-making and analysis outcomes in the planning process.
