White Paper
SAP Multiresource Scheduling (MRS) on
S/4HANA for Heavy Industry
In Heavy Industry high value and critical assets to remain in operation, controls the attainment
of production goals. System to manage Enterprise wide assets is very critical for Heavy Industry.
One of the aspects of effective asset management is managing maintenance operation
efficiently. This white paper throws light on importance and usage of Resource planning with SAP
MRS for Heavy Industry.

Introduction:
Planned, preventive, outages and shutdown
demand simple to complex level of planning
to ensure timely completion of maintenance
and upkeeping important plant machinery
and supporting assets. Failure or outage of
any of the critical asset during production or
manufacturing incurs huge productivity
losses.
Asset owners and planner are always
struggle around planning the maintenance
operation and at the same time making sure
that required skill human resources, spare
parts and material are available. There are
quite few industry grade software solutions
available right now to address this critical
business function in Enterprise asset
management (EAM) space.
SAP itself advocates two important tools for
Resource Scheduling; Multi Resource
Scheduling know as SAP MRS and Click
software. Being useful because of in-built
integration to have visibility about tools,
spare parts availability in addition to human
resources, MRS is always best suited tools
for Resource planning in Heavy industry.
Significance:
Every asset in mills and production plants are
owned by responsible O&M staff. These
Field Supervisors and Managers works in co-
ordination with operation plan, plan for
outages, shutdowns and preventive
maintenance work. The Asset planner define
schedule for work to be undertaken based
on these known/planned events. On the
other hand, Maintenance team usually is
Central unit attending entire scope of
maintenance for plants or different mills on
a Location.
Asset planner plans the maintenance
operation for these known events
considering production or manufacturing
plan. There total output based on efficient
planning performed by these Asset Planners.
Maintenances team however is stretched
between these know events as well as
breakdowns and urgent upkeeping
(unknown) requirements. Planning
resources on different type work as well as
ensuring that resources are not overbooked
or are available to take up planned work is
challenging in absence of working resource
planning tool.
Challenges:
Maintenance Resources work in different
shift based on the responsibility, expertise
and maintenance demand. Knowing the
availability of resources or team capacity
ahead of time enables informative
scheduling of maintenance operation.
Usually resource shift is planned in HCM
system. Lack of integration between
resource planning and resource work
schedule bring down less confidence in
seeing HCM data for reference. Moreover,
HCM work schedules are changed
periodically and less to adjust maintenance
operation demand.

Maintenance resources are usually grouped
based on their skills and expertise. Working
hierarchy within maintenance organization
most of the time differs than the HCM
organization hierarchy. This adds more
problem when it comes to define
responsibility of managing resources for
planning purpose.
Although the availability human resources
play pivotal role in completing the
maintenance operation, without tools,
equipment and spare parts it’s impossible to
complete maintenance task. If availability
tools, equipment and spare parts are
purposefully ignoring, it adds up for either
additional inventory (cost) or loss of
productivity due non-availability of these
resources.
Not every resource is maintained as
companies full time resource. Its normal to
engage contract resources to work on
maintenance operation. Better decisions are
taken about utilization of inhouse vs external
resources when planner can see availability
side by side. Most of the time contract
resources are outside resource planning tool
and managed at very high level without
considering their work schedule and
advance planning.
SAP MRS Answers to
Heavy Industry:
SAP MRS is the best suited resource planning
tool for heavy industry due to number of
reasons however it proves to be
undoubtedly winner if the Company is
already using SAP for HCM, Maintenance
operation, Material management and other
business processes. Following key functions
are useful for heavy industry resource
planning function which MRS addresses
well.
1. Capacity Planning of Resources based on
shift and individual work schedule. MRS
defines available capacity of resources or
team based on actual work schedule of
resources rather than referencing group
level work schedule. This helps Asset
Planner while scheduling the
maintenance work as well as dispatching
work for execution. Based on demand
plan, Planner can change resource work
schedule without impacting HCM work
schedule.
2. Flexible way to keep maintenance work
scheduling and resource planning
separate so that other dependent plans
upon maintenance work stays on time.
Resource planner has responsibility to
make resource available based on
priority and urgency provided in
maintenance schedule.
SAP MRS can be defined both way where
resource planning follows the
maintenance schedule and other way
where maintenance schedule gets re-
planned based on resource plan.
Although later is not the best fit case for
heavy industry.
3. SAP MRS enables to look at overall
resource availability by bringing full time

and temporary resources together in one
view. Rather checking at individual group
or team level for contract (temporary)
staff. Capacity can be checked and
assigned at individual resource level.
This brings lot of values by providing way
to compare internal capacity vs outside
capacity and utilization.
4. Individual technicians and maintenance
resources get to see work assigned to
them and timeline to complete the
assigned work. It can show the changes
in working time without HCM
department’s involvement to change the
shift of resources. Resource can confirm
the work performed from their hand-
held device.

functions SAP MRS offers. To know more
