Functionality

This function module provides all the available pick-up and drop-off points (P&D) or empty pallets zones for each given source or destination structure (SRCDST) in the required direction. There are two different types of P&Ds or empty pallets zones:

• Assigned P&Ds/empty pallets zones:

These are zones with the corresponding zone functionality that are assigned to the source or destination zones.

• Free P&Ds/empty pallets zones:

These are zones with the corresponding zone functionality that are not assigned to a specific zone (for example, P&Ds which can be assigned to any zone).

The function module imports

• the site,

• the information whether the serving node is a P&D or a empty pallets zone,

• the storage bins or nodes (source or destination structures)

• and the required direction (entry/exit).

The function module exports the available nodes and detailed information for each source or destination (storage bin/node) with a given direction. The data contains:

• data on all available nodes including details

• a list of free P&Ds that can be assigned to any zone in both directions.

Note that in the database structure the P&Ds and empty pallets zones are defined as zones that might have multiple nodes assigned. The function module exports only one representative node for each zone. This representative node is one of the non-blocked entry nodes.

The function module exports definition errors related to the imported data in two separate tables:

• Zone definition errors

• Node definition errors

The function module exports an additional table for errors caused by importing an extra parameter.

Example

Notes

The function module imports source and destination data in a structure that consists of zone and node data. For processing, the system can only use one of them. If zone and node data are imported, the function module raises a flag of extra parameter in ET_SRCDST.

Definition errors occur either in ET_ZONES (in case of zone definition errors) or ET_NODES (in case of node definition errors).

If imported source or destination data causes an definition error or an extra parameter error, the function module processes the one that is free of errors. In this case, it provides the optional nodes as if only source or destination data was imported.

The function module raises an exception if the imported site is not defined since the system cannot continue processing.

The function module raises an exception if it cannot find any node.
