Lot Controlled Planning

Material Pegging, Shelf-Life, Wear

Key Concepts

In PlanetTogether, an Item can be Lot controlled. This means that any material (on-hand quantity or supplies from production or purchases) will be stored in separate Lots rather than together in the warehouse. This enables the system to model Material Pegging, Shelf-Life, and Wear.  

Material Pegging

To enable material pegging, set the item’s LotUsability property to "Controlled" in the Item Details window of the Inventory Plan.

If any demands specify a particular "Lot Code," then the on-hand lot of supply will need to specify that same Lot Code used by that demand. You can import a lot with many codes already specified. If a Material Requirement specifies a Lot Code, it will only consume material in the lot that matches its Lot Code. Lot Codes can also be specified on Jobs and Purchase Orders.

PlanetTogether MRP will peg generated supplies (Job Products or Purchase Orders) to demands (Material Requirements, Sales Orders) for items whose LotUsability is NOT "Uncontrolled."

Shelf-life

Industries such as food, beverage, chemical, and pharmaceuticals often have materials or products that can no longer be used or sold after a specified amount of time has passed since their purchase or production date. PlanetTogether has several tools to help planners and schedulers create schedules that follow limitations related to perishable inventory. 

Shelf-life can be defined for each item, and it defines the length of time after the item is produced when it should no longer be used as a job material. To enable Shelf-Life, set the Item’s LotUsability to "ShelfLife" and specify a time span in the Shelf Life field.

The supply from lots will expire and become unusable by demands at the Production date plus the shelf life span. For example, if a job for an item with a shelf life of two weeks is scheduled to finish tomorrow, the material from this job will be unusable two weeks after tomorrow.

Wear

The usage of the parts is tracked and may be used to determine whether the parts can be used. To configure Wear, set the item’s LotUsability to "Wear" and specify the maximum number of times a lot can be used in the Material Requirement’s MaxEligibleWearAmount field. The Product field "NumberOfUsagesToBeAdded" will continually update the Wear running total amount.
