Usage of Constrained Demand vs. Sales Forecast in IFS Demand Planner

Hello everyone,

I would like to ask whether anyone using IFS Demand Planner is working not only with a standard sales forecast but also with constrained demand.

In our current setup, we are using Demand Planner where the forecast is maintained in the Adjusted Forecast. This forecast is then transferred to the Master Schedule and serves as the basis for both procurement and production planning.

However, we are facing a common challenge:

  • The forecast often represents unconstrained demand, i.e., what sales teams would like to sell, without reflecting actual production or capacity constraints.
  • Alternatively, the planning team adjusts the forecast down to a constrained demand level, so that it better reflects what we are realistically able to produce and deliver.

I would be interested to understand how others are handling this:

  • Are you working with both unconstrained and constrained demand in parallel?
  • How do you incorporate capacity constraints into your planning process?
  • Do you manage this directly within Demand Planner, or do you handle it later (e.g., in Master Scheduling or another step)?

Also, could anyone advise on how to set this up so that both forecasts can be maintained and used in parallel? Would you recommend handling this within Demand Planner, within the Master Schedule, or using a different approach or tool?

Any insights, best practices, or recommendations would be greatly appreciated.

Thank you in advance!

Hi,

I would suggest that you look at the IFS S&OP (Sales and Operations Planning) functionality to handle the Unconstrained vs Constrained demand requirement and other resource planning scenarios.

The functionality is integrated with MS Level 1, Demand Planning and RRP (Resource Requirements Planning).

This PPT and recording are from IFS Applications 10, but the concepts are the same as those in IFS Cloud.

Hello Daniela,

I agree with what Richard describes above.

But I would also like to highlight:

In Master Scheduling and you can also try increase the forecast in another MS Set <> 1 (MS Set is called Material Planning Scenario from 25R2). And then test the production plan in RRP, focusing on a few key resources.

Remember MS Set 1 represents the live scenario - here we should work with a constrained forecast.

***

In 26R1 we introduced MRP and CRP simulation, so you can explode the unconstrained forecast down through the BOM, using MRP, and then look at Work Center Load and Labor Load. This will give you are very detailed picture.

Please remember that MRP Simulation component doesn’t come with MRP, you need to buy this new component.

Cheers,

Mats

Hello,

thank you very much for both of your responses. I really appreciate it.

It’s great to see that you shared both the presentation and the video — this is exactly what we were looking for. We will continue to analyze the content, learn more about it, and start testing the approach on our side.

Thank you again for your support!
