MRO stands for Maintenance, Repair and Operations.

This inclued material types as production resource and tools, operating supplies, maintenance assembly and spare parts.

In many organizations because of the number of devices or products that need to be maintained or the complexity of systems, there is a need to manage the information with software packages. This is particularly the case in aerospace (e.g. airline fleets), military installations, large plants (e.g. manufacturing, power generation, petrochemical) and ships.

These software tools help engineers and technicians in increasing the availability of systems and reducing costs and repair times as well as reducing material supply time and increasing material availability by improving supply chain communication.

As MRO involves working with an organization’s products, resources, suppliers and customers, MRO packages have to interface with many enterprise business software systems (PLM, ERP, SCM, CRM).

One of the functions of such software is the configuration of bills of materials or BOMs, taking the component parts list from engineering (eBOM) and manufacturing (mBOM) and updating it from “as delivered” through “as maintained” to “as used”.

Another function is project planning logistics, for example identifying the critical path on the list of tasks to be carried out (inspection, diagnosis, locate/order parts and service) to calculate turnaround times (TAT).

Other tasks that software can perform:

Planning operations,

Managing execution of events,

Management of assets (parts, tools and equipment inventories),

Knowledge-base data on:

Maintenance service history,

Serial numbered parts,

Reliability data: MTBF (mean time between failures), MTTB, MTBR (mean time between removals),

Maintenance and repair documentation and best practices,

Warranty/guarantee documents.

Many of these tasks are addressed in Computerized Maintenance Management Systems (CMMS).

In SAP you can find information about the scenarios in SAP for Aerospace & Defense.


Stock keeping unit (SKU) is an identification, usually alphanumeric, of a particular product that allows it to be tracked for inventory purposes. Typically, an SKU is associated with any purchasable item in a store or catalog. An SKU is not the same as a product model number from a manufacturer, although the model number could form all or part of the SKU. The SKU is established by the merchant.
