  1. Trains
  2. Bridges / Tunnels
  3. Submarines
  4. Refineries
  5. Water Treatment Plants

SAP MRO Module

The MRO solution encapsulates any maintenance environment - typically one dealing with large assets that are subject to a high degree of regulation or complexity. 

SAP Airline Solutions

SAP MRP is a key part of the SAP Airlines Solution and ultimately, part of the Aerospace & Defense (SAP for A&D) solution portfolio.  It has been developed based on continuous input from SAP Airline Customers, through their membership in the SAP Airline User Group, which meets annually to discuss their SAP aviation maintenance requirements.  It is part of the comprehensive SAP Solution developed to support the aerospace industry. 

Follows SAP Development Guidelines

As an SAP-endorsed business solution, iMRO 6.9 is complementary to SAP software offerings, has been developed in accordance with SAP Development Guidelines , and provides additional choices and flexibility for businesses running SAP applications.  This latest release is certified on the SAP ECC 6.0 Enhancement Pack 6 platform, including certification on SAP Business Suite on HANA.

Designed to Spur Innovation and Value Creation

 Complex asset maintenance businesses rely on SAP to help them acquire, install, operate, overhaul, and ultimately to dispose of their complex, expensive assets.  SAP technology provides end-to-end solutions that support each of these activities, within complete eco-system of manufacturers and MRO service providers. 

Boosting Aftermarket Service Business

Integration with the SAP HANA platform, enterprise mobile apps, analytics solutions and SAP 3D Visual Enterprise Applications support manufacturing processes and help original equipment manufacturers (OEMs) transform their aftermarket services business. Aftermarket services typically offer higher profit margins than the sale of capital equipment and therefore OEMs are increasingly looking for ways to tap into this lucrative yet challenging market.

Enables Business Transformation Building Blocks

SAP iMRO Solution is a key enabling solution for business transformation.  Through the use of fapid templated implementations MRO business transformation projects drive down project risk, increase project ROI and improve overall MRO business processes.   Through the use of global template design and rollouts, customers can leverage the SAP S/4HANA platform and partner products to achieve entirely new, innovative, high-value process capabilities.

Induction Workbench

The iMRO Induction Workbench Provides an Efficient In-processing System for Incoming Parts

The Induction Process consist of the following steps -

  • Creating a physical asset in the system for tracking purposes (accountability, shipping) through serial number creation / receipt
  • Setting up the internal objects used to
    • Manage scheduling of high-level work
    • Manage cost collection at assembly / aircraft / module level for future COPA / RA (Internal) or Resource-Related Billing (RRB)
  • Creating a mechanism to track parts as they are removed from the structures / assemblies in the subsequent phase of dispositioning
    • Getting the process to a place where the subsequent phase of dispositioning is supported through:
      • Work step references (repair orders – complex assets / aircraft process)
      • Labor collection (dispositioning labor and component repair)
      • Placeholder for in-process material reservations (component repair)
      • Support structure for external subcontracting

The iMRO Induction Workbench (SBX) triggers all the steps required to induct components, complex assets, or aircraft in a single transaction:

  • Generation of Sales Orders
  • Work scope input
  • Generation of Returns Delivery
  • Tally and Physical Receipt of End Item
  • Creation of Repair Work Order (component scenario) or a list of End Item Work Orders (complex / aircraft scenario)
  • Print Work Order
  • Issue Part to Repair Work Order (component scenario)
  • Creation of External Repair Purchase Order
  • Call Inspection Workbench (iMRO-IBX)
  • Call Electronic Work Instructions (iMRO-EWI)

Sub-Process of the Above Steps:

Creation of End Item Batch / Equipment, Operative Networks and Projects (in the complex / aircraft scenario).

Complex Asset/Engine Induction

Create Returns Delivery:

  • A returns delivery item is created for post-release shipment of the engine back to the customer - the storage location indicated in the configuration table for the Induction Schema / Notification Type will determine the source location for the delivery


Receive Complex Asset into Stock:

  • The complex asset will be received into the storage location specified in the Returns Delivery
  • A Material Document is created on saving – this will represent the engine receipt date

Create Strip and Build Orders:

  • Order generation method dependent on customizing for the Induction Schema
  • The project generated during Sales Order creation must be released (CJ20N) as a prerequisite for the order generation

Modification Workbench

  • Induction of a Service Bulletin or Directive received from a regulatory body or customer (Mod)
  • Mod Review Process and the final Release of the Mod
  • Identification of applicable technical objects for the Mod
  • Creation of a post-modification variant for a master parts list (MPL) node
  • Creation of a new MPL node introduced by a Service Bulletin issued by an OEM
  • Link one Mod or Engineering Order to another Mod with relationship types that will determine how the embodiment notifications and maintenance plans of these linked Mods are processed
  • Embodiment Rules for the Mod per Customer
  • Creation of Master Plan for the Mod, and subsequent
    • Operative Maintenance Plans (for repetitive) OR
    • Notifications (for one-off work) per applicable technical object
  • Report on the Embodiment Status of the Mod

Effectivity Monitoring and Maintenance

Applicability Rules Sub-Screen:

  • This is where applicability values and ranges for the Engineering Order being processed are maintained. These values are used to search for applicable technical objects such as equipment, functional location, or part numbers, which are classified using the same characteristics with characteristic values meeting the applicability ranges on the Engineering Order
  • The class is defaulted from customizing for the document type. It has to be created via transaction code CL02 and maintained in table /AXONMBX/CU04A.
  • Depending on values selected in the Applicability Rules sub-screen, applicable technical objects will be identified and displayed in the Linked Technical Object sub-screen on the right by using the ‘Identify Linked Objects’ button. Only technical objects with a characteristic matching the applicability rules sub-screen are identified as applicable.
  • The technical objects identified will be deemed applicable to the Engineering Order and document object links will be created on saving the transaction.

Inheritance sub-screen:

  • A source document can be specified from which copying / inheritance of applicability rules can be performed.
  • Use either Copy or Reference functions as necessary depending on whether the Engineering Order should adopt identical or just similar applicability rules as compared to the source document
  • The ‘Copy’ function copies applicability rules from the source document, allowing each to be edited independently. Changes to the applicability rules on the source document after the copy are not reflected in referenced Engineering Orders

The ‘Reference’ function creates a persistent link between the applicability rules of the source document and the Engineering Order. Any subsequent changes to the applicability rules of the source document after the ‘referencing’ are automatically reflected in all referenced Engineering Orders

Linked Technical Objects sub-screen:

  • All technical objects in the system – equipment records, functional locations, materials and MPL nodes – that are applicable to the Engineering Order being processed are displayed here. These objects can be populated automatically via the Linked Object features (classification), or can be input manually.
  • Records are marked as either:
    • Deleted – will be removed on SAVE
    • Green Traffic Light – are applicable and have previously been stored in the database (object links exist between the Engineering Order and the technical object)
    • Yellow Traffic Light – are applicable according to classification but no object link has yet been stored in the database. A document link will be created on SAVE
    • Red Traffic Light – are not applicable according to classification, however it is possible to manually override. A document link will be created on SAVE
