Hi @Prithika ,

If the plan you've created in Ataccama ONE Desktop is not connected to the server (Ataccama ONE Web), you cannot execute it directly in Ataccama ONE Web. To run the plan created in the one desktop can be done if we create any post processing plan that we create for a particular catalog item on a monitoring project  - or can create a workflow. 

Hope this helps !
