The Dynamic Workspace action in Auomations on FME Server allows you to run multiple workspace with the same parameters with the input from a FME Server Auomation Writer.
Instead of using the FME Server Auomation Writer as input to the Dynamic Workspace, this should allow one to select multiple workspace from multiple repositories with same parameters, in an Auomation directly in a Dynamic Workspace Action.
This makes it easier configure an Auomation Writer with the use of only one Action, instead of multiple actions for multiple workspaces.
