MRP for spares and consumable items

Hello,

My company holds and manages huge quantities of machine spares and consumables for which we would like to use the MRP functionality to plan the purchases. I have gone through the MRP functionality to see how to set this up, but can only see that MRP works well for items that are /consumed/ through sales orders or production orders. Spares and consumables will never be sold or used in production, so we tried running this using only the parameters of minimum levels and reorder quantities, however, this does not trigger any /actions/.

Has any of you used MRP for consumables or spares? Or do you have any ideas on how I can achieve the good planning for spares and consumables purchases?

Thank you

Hi,

If your organization has development capabilities, you can customize MRP to consider your consumables and spares. You can set up custom MRP parameters and logic to trigger purchase actions based on your specific needs.

Or you can use manual planning techniques. You can set minimum and maximum stocking levels for spares and consumables based on your business requirements and manually review and adjust inventory levels as needed. This method allows for more flexibility and control over the planning process.

Best regards,

Kevin

Hi Sophie,

As you mentioned that for spares and consumables products you want to setup based on minimum level as trigger. You can use Coverage group - Min/MAx and then map this correctly on Released Product with defined Min/Max level. Now, MRP will consider On hand stock, Issue and receipt stock, if it is below Min level defined, MRP will trigger Planned order.

To test this you can create a new product with ZERO stock and Define Min = more than zero, Max= Higher value than Min.

I am assuming that all other setups are already completed by you. But if this doesnt work, you may share config snapshot which you did and based on that this can be looked further.

Thanks,

Gaurav

As others have mentioned or asked, what is your sourced of demand. Master planning/MRP can react to more than sales or production consumption. IF you have Transfers orders, inventory journals, etc. that have requirements to use or consume inventory, those trigger Master planning as well. Forecasts can trigger master planning.

Often for Spare parts and consumables, companies will setup a safety stock (min/max), or Forecast to project the inventory they need to keep on hand to service customers. If you do not have discrete sales orders, are you integrating D365 with another system that handles service orders to trigger spare parts and consumables?

Perhaps some of this documentation may help?:
