Usage and differences between MRS , RSH and FSM

[sp0123]

Dear Experts,

We are working on a requirement for  Resource Scheduling for one of our client.

SAP has 3 products available i.e. MRS , FSM and RSH.

Can someone tell me what are the usages of those and the differences between them? 

Thanks and Regards,

S Kumar

Hi S Kumar,

MRS 10 has an end of life for SAP S/4HANA in 2027 and for SAP ECC in 2030, hence we are not actively positioning this solution for new customers. With that we have two successors, SAP S/4HANA Asset Management for resource scheduling (RSH), and SAP Field Service Management (FSM).  At a high level, the natural successor for MRS is SAP RSH for in plant maintenance operations and SAP FSM for field service related operations. Here is a blog I wrote on the topic which goes into much more detail. You can also find a demo video of RSH here, and FSM demo videos here. 

Hope this helps,

Thanks,
Ryan
