In May 2026, SAP announced that its two maintenance scheduling products, SAP Multiresource Scheduling (MRS) and SAP S/4HANA Asset Management for Resource Scheduling (RSH), will be folded into SAP Field Service and Asset Management (FSA), the renamed and expanded version of SAP Field Service Management (FSM).
If you plan maintenance with either of them, nothing changes this year. SAP's own advice is to keep using what you have. But there are three things you need to be aware of:
- MRS sunsets at the end of 2030.
- RSH stopped getting new features at S/4HANA 2025 FPS0, the initial shipment of S/4HANA 2025.
- FSA's planning capabilities are arriving release by release, with general availability planned for the end of 2026.
This article explains what MRS and RSH are, what SAP has said about them, which dates apply to your system, and what your options are from here.
What SAP MRS and RSH are.
SAP Multiresource Scheduling (MRS) is SAP's long-serving add-on for assigning work to people and equipment. It has been around since the R/3 days, runs on SAP ERP 6.0 (better known as ECC) and, in a separate version, on S/4HANA.
SAP S/4HANA Asset Management for Resource Scheduling (RSH) is the newer of the two. It runs inside S/4HANA Asset Management, uses Fiori apps rather than SAP GUI, and is built around work center capacity. It does not run on ECC.
What SAP announced about MRS and RSH in May 2026.
At Sapphire in May, SAP renamed Field Service Management to Field Service and Asset Management and named five planning and execution products it plans to consolidate into it: MRS, FSM, RSH, SAP Cloud 4 Projects Resource Management, and SAP Maintenance Scheduling and Optimization.
SAP's product announcement says three things about MRS and RSH:
- MRS is in maintenance mode with no major enhancements planned, and SAP plans to sunset it by December 31, 2030.
- If you run MRS on ECC or S/4HANA with the dispatching scenario, SAP recommends continuing to use it for the time being.
- RSH will get no roadmap updates after the S/4HANA 2025 FPS0 release. You can keep using it for work center capacity-based scheduling while you revisit your license transition and migration to FSA.
Here is what has shipped so far:
Release 2605 went live on June 2, 2026, and brought the new name, asset-centric vocabulary, and one planning feature: a Workload and Capacity view inside Planning and Dispatching.
Release 2608 followed in August 2026. It made the capacity view more realistic by accounting for technician absences and showing workload by day, and it let schedulers spread work across work centers and review draft changes before publishing them.
SAP's target for general availability of the full FSA solution is the fourth quarter of 2026.
So the pieces that would let FSA take over from MRS or RSH at a plant are not all there yet, but they are on their way. That is why SAP's advice is to keep using MRS for now, and keep RSH while you plan the move.
The dates that apply to you.
The dates relating to RSH, MRS, and FSA are confusing, so we have brought them together with the latest information we could find (mid-October 2026).
You can read more in our guide, SAP ECC to S/4HANA: the maintenance leader’s guide to the migration.
A few things that stand out.
No deadline on this table is before the end of 2027. The first real deadline is the end of mainstream maintenance for ECC and MRS 10.0, and extended maintenance moves that to the end of 2030.
Support ends for MRS and ECC on the same day. Mainstream maintenance runs out at the end of 2027 and extended maintenance at the end of 2030, for the ERP and the add-on alike. For MRS on ECC, the sunset does not force a decision that ECC was not already forcing.
RSH is frozen, not finished. It is getting no new features, but S/4HANA 2025 has mainstream maintenance to the end of 2032, and SAP says you can keep using RSH for capacity-based scheduling in the meantime.
Licensing.
If you run MRS, moving to FSA may need a new cloud subscription. DSAG, the German-speaking SAP user group, raised this in May, arguing that existing MRS customers should not need another license to keep functionality they already use.
As of October 2026, we have not seen an SAP statement that settles it.
RSH customers are in a similar position: SAP's announcement tells them to revisit their license transition as part of the move to FSA, without clarity on what that involves.
FSA itself is sold as several subscriptions, which our FSA explainer breaks down.
Next steps, by situation.
Most SAP maintenance teams are in one of four situations.
In each, the underlying choice is the same: follow SAP's scheduling roadmap, or move planning to third-party software that works next to SAP.
You run MRS on ECC and plan to migrate to S/4HANA before 2030.
SAP recommends staying on MRS for now if you use it to dispatch work to individual technicians. Once the migration is done, each SAP option comes with a catch: MRS for S/4HANA ends in 2030, RSH gets no new features, and FSA is still arriving, with the MRS licensing question open. Third-party planning software that works on both ECC and S/4HANA can take scheduling out of the migration project altogether.
You run MRS on ECC and plan to stay on ECC until 2030.
With extended maintenance, MRS and ECC both run out of support on December 31, 2030. You can keep MRS until then, but if you leave scheduling until the ERP project, you will be changing both in the same year. Moving scheduling earlier, to FSA or to third-party software, keeps it out of that project.
You run RSH on S/4HANA.
New features for RSH stopped at S/4HANA 2025 FPS0, but it still works. SAP's advice is to keep using RSH for capacity-based scheduling and revisit your license when the FSA migration option is ready. One SAP partner, valantic, has mentioned the second half of 2027 for that, but we could not confirm it.
You schedule in CM25, spreadsheets, or custom-built software today.
The MRS and RSH dates do not affect you. If you're on S/4HANA, check with IT whether you can still use CM25, because SAP is phasing it out. If you plan in spreadsheets or custom-built software, the bigger issue is that your weekly plan lives outside SAP. Our comparison of SAP scheduling software covers your options.
Where SAP's scheduling work is going.
SAP's scheduling investment is visibly moving to FSA and to Autonomous Enterprise Joule agents, and away from MRS and RSH.
On October 8, 2026, SAP announced new agentic capabilities for its Asset Operations Assistant. They support initiating, screening, and simulating maintenance requests, with general availability planned for the fourth quarter of 2026.
SAP's product pages already list a Maintenance Planner Agent and a Field Service Dispatcher Agent, both with beta registration open.
Where FastPlan fits.
Enterprises like yours want to keep SAP as their system of record. It is critical software for running the business, and switching to a different ERP system is a years-long project.
That is why many enterprises are turning to third-party options that enhance SAP and get more out of the data held in it, while reducing the dependency on the SAP roadmap.
FastPlan gives planners a visual planning and scheduling workspace specifically for SAP PM and CS.
Companies choose it because:
It runs on SAP ECC and S/4HANA. Move planning from MRS to FastPlan on ECC, and your planners keep the same workspace after you migrate to S/4HANA.
Planners keep capacity-based scheduling and get their own views. Work is scheduled against real work center and employee capacity, absences included, and each planner can build views for their own role or work area.
Plans can be tested before they are committed. The working plan stays separate from the live orders in SAP until a planner commits it. So they can save a plan B, C, and D beside the default and see how each affects overall capacity before committing to SAP.
It does not depend on MRS, RSH, or FSA. FastPlan connects to standard SAP EAM through FastCloud, Arkyn's SAP integration, so whatever happens to SAP's scheduling products, your planning keeps working. It can also run alongside MRS or RSH while you switch over.
Where to next?
SAP's advice to stay on MRS and RSH for now is sensible, and if FSA is the right place in 2027 or 2028, a planning layer next to SAP does not stop you getting there.
