Strategy: Stringent FIFO Across All Storage Types

Explanation of the Strategy

It is generally assumed that only one picking strategy is allocated to each storage type. However, a strategy based on the storage type is not usable in all sectors of industry.

In WM, it is possible to pick stock according to the FIFO principle by taking into account all quants within a warehouse. In this case, the system does not scan individual storage types in sequence but it proposes the oldest quant in the entire warehouse as the quant to be removed from the warehouse. The system does not take into account the picking strategies specified for the individual storage types. This would lead to inconsistencies.

Some storage types should be excluded from the stringent FIFO strategy, otherwise incorrect picks would result. For example, the interim storage area for differences should be excluded from the stringent FIFO strategy. The stringent FIFO strategy is set or switched off in the table Exclusion of storage types from Stringent FIFO (see below).

Setting up the Strategy

In the Storage Type Search table enter three asterisks ( *** ) in the first Storage type column as illustrated below.

Storage Type Search Table

WNr	Act.	TypIn	B	S	Class	WPC	Ref	1	2	3	...(Stor.Types)
001	A							005	001	004
001	A			K				001
001	A		Q					024
001	A	SFI						***

Note Note

When you create pick transfer orders, you can also enter *** in the field for the source storage type in the transfer order preparation screen or in the transfer order item screen.

End of the note.

It is necessary to exclude some storage types, such as the interim storage area for differences, from the stringent FIFO strategy. In the table Exclusion of storage types from Stringent FIFO select the No stringent FIFO column for the storage type. The system then ensures that this storage type is not used for the stringent FIFO picking strategy. This indicator should be set for all interim storage types.
