Changing parameters in a runbook after it was synced in SCSM may change its state to “Invalid”. To fix this you need to go in SCSM and delete the synced runbook and run the Orchestrator connector again. If your SCSM machine is slow ( like mine :) ) you need to wait a little until the “Delete” action appears in the console, on the first instance you get only “Refresh”
