(#VIS30925)

1) Between 2 Main zones, no Flow bundle paths can be shown.
2) In the dialog 'Edit flow bundle term'/'Traffic types' a warning is shown:
'These settings are ignored for implicitly stored paths (->LUCE). Instead, all paths traversing active links are considered, i.e. all options except external trips.'

The results of the 'Equilibrium assignment LUCE' are not stored as path trees, but in a different structure as implicitly stored paths (called 'bushes') which leads to limitations for Procedures that are based upon path trees:
1) Flow bundles cannot take any Main zones into account. (This is documented as bug VISUM-20937.)
2) Flow bundle Traffic types cannot be taken into account.
