SAP MRS (Multi Resource Scheduling) - A ready reference (Part 1)
Being a beginner in SAP MRS is a challenge. As a BW techie, When I started in MRS Module, I found a lot of scattered information but there is no article or blog with consolidated information even on basic terminologies of SAP MRS.
This blog is my attempt to provide an insight of basic aspects and terminologies of SAP MRS to a novice.
Introduction to MRS
SAP Multiresource Scheduling enables you to find suitable resources for demands and assign them to the demands. Demands are units of work from the areas of Plant Maintenance, or Project System, for which a resource is to be planned.
It is End to end scheduling process.
Salient features of MRS --
- Effectively manage high volumes of resources and demands for your service, plant maintenance, or project business.
- Get a real-time view of resources and project assignments with a user-friendly planning board.
- Drag and drop” to update project details.
- Boost productivity and reduce operational downtime.
- With the ability to view, analyse, and interpret order data, you can easily match technician skills to assignments – for better repair work and improved service quality.
