Purchase order Quantity: Multiple of Fixed Amount

[Phil_P]

Hello there, SAP Community,

I’d like to configure Material master data for fixed purchase quantity.

I have a material that is sold in fixed multiples of 1000.

So, when I (Manually or MRP) create a purchase requisition/order, only multiples of 1000 are allowed as purchasable quantities. Also, the minimum purchasable quantity is 2000 units. So, if the MRP requires 1001 units, a purchase order for 2000 units will be created.

Allowed: 2000, 3000, 4000, ...

Not Allowed: e.g., 500, 1500, 1111 ... 

Where can I configure this behavior?

Can this also be controlled for manually created purchase requisitions and purchase orders?

Kind regards,
Philipp

Solution to Configure Fixed Purchase Quantity in SAP Material Master:

1. Set Fixed Lot Size in Material Master:
Go to MM02 (Change Material Master).
Navigate to the MRP 1 View and set Lot Sizing Procedure = FX (Fixed Lot Size).
Enter Fixed Lot Size = 1000 to ensure requisitions are always in multiples of 1000.

2. Define Minimum Order Quantity:
In MRP 2 View, set Minimum Lot Size = 2000 to enforce a minimum purchase quantity.

3. Check Rounding Profile (Optional):
In MRP 1 View, assign a Rounding Profile if required to adjust order quantities to multiples of 1000.

4. Verify Scheduling Agreement or Info Record:
Ensure the Purchasing Info Record (ME11/ME12) has the correct multiples defined under "Order Unit."

After these changes, MRP will always generate purchase requisitions in multiples of 1000, with a minimum of 2000.

It seems those steps work only when Purchase Requisition has Creation Indicator as "B - MRP" . Is there a way to predetermine or assign automatically - maybe with warning/error message - when Creation Indicator is "R - Manual"?
