MRO Material Management

MRO Material Management

Summary: The MRO material management features provide the foundation for handling materials, material master data, reservations, storage locations, and goods movements in MRO workflows. The central objects are Material, MaterialMaster, Reservation, GoodsMovement, and StorageLocation. Materials are linked to master data and storage locations. Reservations link materials to tasks and define planned or actual quantities for maintenance work.

MRO material management is used to support maintenance work with the required spare parts, consumables, tools, or other material items.

In a maintenance workflow, users may need to know:

• which material is required for a task
• which material master data belongs to a material
• where the material is stored
• how much material is available
• how much material is already reserved
• which reservations exist for a task
• whether a reservation is planned, confirmed, issued, cancelled, or expired

The material management implementation separates the general material catalogue from the actual material quantity and reservation handling.

Basic concept

The material management implementation is built around the following main objects:

Object	Type	Purpose
MaterialMaster	Master data	Defines the catalogue entry for a material, including item number, unit, packaging, manufacturer data, and material type.
Material	Quantity-bearing MRO object	Represents a material instance or stock entry in MRO. It links to a material master and a storage location and exposes quantity, reserved quantity, and available quantity logic.
Reservation	Workflow / transaction object	Represents a material reservation for a task. It links a material to a task and stores planned and actual quantities.
GoodsMovement	Base class	Provides the common QUANTITY property used by both materials and reservations.
StorageLocation	Storage master / location object	Represents a physical storage location and stores storage-related information such as storage type, dimensions, access type, and occupancy status.

Core idea: MaterialMaster defines what the material is. Material represents the material in the MRO stock or material context. Reservation links a material to a task and reserves a planned quantity for maintenance execution.

Object overview

Object	Class name	Base / inheritance	Main relations
Material	UBIK.MRO.Material	Inherits from GoodsMovement	LK_MATERIAL_MASTER, LK_STORAGE_LOCATION
Material Master	UBIK.MRO.MaterialMaster	Master data class	Referenced by Material via LK_MATERIAL_MASTER
Reservation	UBIK.MRO.Reservation	Inherits from GoodsMovement	LK_TASK, LK_MATERIAL
Goods Movement	UBIK.MRO.GoodsMovement	Base class	Provides QUANTITY to derived objects
Storage Location	UBIK.MRO.StorageLocation	Functional location specialization	Referenced by Material via LK_STORAGE_LOCATION

GoodsMovement

Purpose

GoodsMovement is the base class for material-related quantity-bearing objects.

It defines the common quantity concept used by both:

• Material
• Reservation

Important properties

Property	Type	Meaning
QUANTITY	double	Quantity value for the goods movement. For Material, this is the material quantity. For Reservation, this is the actual reservation quantity and has reservation-specific validation.

MaterialMaster

Purpose

MaterialMaster represents the material master or catalogue entry.

It stores item-level master data that can be referenced by material instances in MRO.

A material master describes the material independently from a concrete reservation or task.

Important properties

Property	Type	Meaning
ITEM_NUMBER	string	Item number or material number of the material master.
PACKAGING_UNIT	string	Packaging unit of the material.
PACKAGING_SIZE	double	Packaging size.
ACTIVE	bool	Defines whether the material master is active.
UNIT_OF_MEASURE	string	Unit of measure used for the material.
MATERIAL_TYPE	int	Underlying integer value for the material type.
MaterialType	enum	Typed accessor for MATERIAL_TYPE.
MANUFACTURER_COMPANY_NAME	string	Manufacturer company name.
MANUFACTURER_PRODUCT_TAG	string	Manufacturer product tag or product identifier.

Material type

The typed material type accessor is MaterialType.

Known values are:

• SpareParts
• Consumables
• Tools

Open point: No explicit SAP or ERP synchronization behavior was found in the inspected classes. ITEM_NUMBER may correspond to an external material number, but the exact SAP/ERP mapping is unclear from the available code information.

Material

Purpose

Material represents a material instance or stock entry in MRO.

It inherits from GoodsMovement and therefore uses the inherited QUANTITY property as its material quantity.

A material links to:

• a material master via LK_MATERIAL_MASTER
• a storage location via LK_STORAGE_LOCATION

It also exposes calculated reservation and availability logic.
