MRP Area, or Sloc MRP? for Supermarket method.

[former_member681640]

Hello Experts.

I'm planning to realize Supermarket method with SAP ERP.
I assume I'm reaching goal. however I need one more step. I appreciate if somebody gives me an idea.

My goal is buildung this setting in ERP.

- Parts deducted from Supermarket storage location (0001) .
- Once the qty of the parts are below of certain point. (like reorder point)
System generate any kind of trigger to goods receipt storage.

- Goods Receipt Storage is set us (0007).

So I set-up like below.

- Setup Sloc MRP Indicator as "2 Storage location stock planned separately" for storage location 0001.(This is Prod. Stor. Location)
- Setup Reorder point and replenishment qty for Storage Location MRP
- Set Storage Loc. for EP as 0007.

This setting works well, let's say 80%.

Storage location 0001 correctly generate transfer request to storage location 0007.

However, we use MRP type PD for this parts.

With MRP type PD, system generate purchase order requisition for future demand.
It works well to prevent future material shortage.

However, in the setting above, MRP type PD for the parts doesn't generate any purchase order requisition for future demand.

I thought MRP runs plant level, but it seems not consider the demand for the storage location 0001 as long as the storage location is set up as Sloc MRP indicator.

I searched in the community, and found we could use MRP area function.

but at the moment I don't have any Idea how to set-up, or even it's possible or not.

Does anybody have experience of the setting "Supermarket" with SAP ERP?

We want to automatize the process as much as possible.

Hello shin_g

I'd create a MRP area for "supermarket" storage location. Then you can define a separate MRP type just for the MRP area. You can use one of V* (reorder point) MRP types. The "supermarket" MRP area will be replenished with MRP planning run. The replenishment method can be customized so a purchase requisition to transfer stock from the main storage location.

I'd discourage using MRP storage location as it's getting obsolete and not supported any more in S/4HANA. MRP areas are more flexible and powerful.

Thank you 3a9e4ce873a94034b33dc62b0ce600ee .

I see, MRP areas are more flexible!

Let me check if I understand correctly?

- With MRP area, I can define completely separate MRP type to Storage Location level.

- The reason why MRP type PD didn't generate purchase order requisition was, I set up Storage location MRP for the location 0001, therefore SAP ERP completely exclude 0001 from any MRP activity, including future demand.

Therefore Plant level MRP type PD didn't recognize their future demand in the storage location 0001.

Hello shin_g

You got it right.

You can define a separate MRP settings in material master including MRP type on MRP area level. As your MRP area can be defined for a storage location, effectively you can define MRP type for a storage location.

Old fashioned storage location MRP doesn't work with requirements. Here you can either exclude a storage location from MRP planning or have it planned with min stock. That's it and that's one of the reasons MRP areas are so much better here.

Hello shin_g

Couple points here.

You need two MRP runs: one on MRP area 0007, then second on MRP area 0001. You can combine it using planning scope definition. Unfortunately planning scope is no longer available in MRP Live in S/4HANA, but I'm trying to get it back. You can support that effort by voting on the improvement request: Planning scope configuration in MRP Live

You are trying to use V1 MRP type for supermarket. V1 is reorder point MRP type, based on consumption. Of course you can include requirements into reorder point planning, but that needs to be activated in MRP type configuration.

I'd start with MRP run in supermarket, 0007 MRP area and make sure that you get correct supply proposals covering reorder point and external requirements. Here you should use external procurement and MRP should generate purchase requisitions.

Next step would be to make MRP assign source of supply to those purchase requisitions, i.e. your standard storage location 0001. To do that you first need to set up stock transfer orders between storage locations - configuration: Materials Management -> Purchasing -> Purchase Order -> Set up Stock Transport Order -> Set up Stock Transfer Between Storage Locations.

Once the issuing storage location is correctly setup in purchase requisitions, you should see requirements in the standard storage location 0001.

Hello All, or hopefully 3a9e4ce873a94034b33dc62b0ce600ee

I did set-up MRP area Supermarket for storage location 0007 and put future demand for 0007.
I also created other MRP area Plant for plant level.

I do the MRP run for both Supermarket and Plant.

but it doesn't generate any purchase order requisition for the demand for 0007.

This is what I wanted to do...

But this is what the ERP currently behave.

I thought the MRP setting solve this, however actually the behavior looks same as Storage Location MRP.

Does anybody have solution of Idea?

After several reading on the Web..

I expect I could assign storage location 0001 for the MRP tipe..

Or I can also try to maintain special procurement type for stock transfer.
