I am aiming to simplify this further, so that a cumulative calculation can be added to any workflow by the addition of a few components and recursive loops.
This is my initial prototype, using 3 “Cumulative Framework” components that work together within a recursive loop. So you simply drop them onto any workflow and join them up in the pattern shown, with zero configuration to provide cumulative calculation functionality.
see also this component which encapsulates the above workflow, so you drop this on your workflow where you wish to do a cumulative calculation and then follow the steps in the component’s help description…
