FIFO Generation Mode

FIFO Generation Mode defines how FIFO Numbers are created to group inventory packs based on age. FIFO Numbers group inventory packs into equivalent age categories. For example, a day-based FIFO Number assigns the same key to all packs created on a specific day, treating them as equal in age when validating the pack for consumption or other transactions. Increased granularity results in more precise FIFO control, however, reduces flexibility when selecting suitable inventory.

This table lists the available patterns:

FIFO Pattern	Description	Example
Year & Month & Day	4 digits for the year, 2 for the month, and 2 for the day.	20260621
Month & Day	2 digits for the current month, and 2 digits for the current day.	0621
Month & Daily Sequence	2 digits for the current month, and 2 digits for a sequence number which increases for each day, a pack of the material is created (this is not quite the same as Month & Day - because the numbers wouldn't increase every day).	0601
Month & Sequence	2 digits for the current month, and 2 digits for a counter per inventory pack.	0601
Calendar Week	2 digits for the current year, and 2 digits for the week number (starting on Mondays) to represent the week (all packs created within the week have the same key).	0630
Shift	2 digits for the current month, and 2 digits that increase for every shift the material is produced (all packs for the same material created within the shift have the same key).	0601
User Defined	Allows for implementation-specific FIFO numbers to be generated, when the standard options do not provide the required values - attempts to observe the Plant Setting for FIFO Number Template. However, can be overridden if something more complex is required.
