To allow moves between transfer zones, you need to define the paths that are used to access the TZ, including paths between TZs and paths from WSTZs to the parallel buffers (PBs). For more information on paths to PBs, see Set up the parallel buffer area (on page 1).
TZ Decker only allows moves between TZs that have a yard path, that is, the yard path model allows moves between those two vertices. Therefore, to allow a move between two TZs, a path must exist in the yard path model between those two TZs. If a TZ is accessible from two paths, such as a common area in the yard, like X-RAY, then it should have two vertices with each vertex connected to its corresponding path.
There should not be a connection between the yard paths on the waterside and the yard paths on the landside. This connection restriction prevents AGVs from getting dispatched to LSTZs for moves and parking.
