Couple of things i would suggest
1) Just try running ttadv5214m000 from the Run Program of Ming.le or Web UI. I dont know how these two(Ming.le or Web UI) works but i think there would be run Program Option in these interfaces. In LN Worktop, Baan V, Baan IVc4 there is a Run Program option, its present in the File Menu.
2)Does the Package Combination of the attached User , who is logging in the Baan System, has the Package VRC b61wk20, in its ts Package or atleast the Package VRC in the Package VRC's derivation structure?Maybe the Package Combination of the attached User doesnt have the Package VRC in its derivation structure
Lastly you could check whether this is happening for more than one Menus or more than one Menus in more than one Package VRC's.
