After modification in a routing plan or creating a new one, there are no changes in Routing Analysis.
The rules' or plans' changes do not affect Routing Analysis not resolving. However, if you change any data related to the termination side (upload new termination prices, add a new termination Account, etc.), and it happens to be after the Dynamic Routing Table has been already updated, the cause would be that the Dynamic Routing Manager has not yet been run to reflect those changes.
You should run Dynamic Routing Manager (System > Task Scheduler section) every time changes are made to a routing plan. Only after that the Routing Analysis will show the correct data.
