Supply Protection of advanced ATP in SAP S/4HANA
This blog is for SD consultants. This functionality can be used from SAP S/4HANA OP2021 FPS0 version. However, it also works with SAP S/4HANA 2022 onwards, and SAP S/4HANA Cloud, private edition.
What is Supply Protection
Supply Protection is for promised minimum selling quantities for each customer.
SAP S/4HANA OP2020 FPS00 or upper version. Fiori server must be installed. The user must have “SAP_BR_ORDER_FULFILLMNT_MNGR” role.

“With Supply Protection for Specific Document Types” flag should be On
Execute App ID:F4569 “Manage Supply Protection”
Click Create button.
Set the mandatory fields.(Red * Marked)
Supply Protection is defined by Material and plant combination.
*“Consumption Based on” can be done as “Requested Delivery Date” from SAP S/4HANA OP2021.
Set planning Period Type, start date and end date.
Set Characteristic 1 is mandatory. You can define up to two characteristics for Core Protection ( Horisontal) .
You can add additional fields of Sales Orders and Stock Transfer Orders via “Characteristic Catalog” Fiori Apps.
Prioritized Characteristic is option. You can define over 2 characteristics, if you need.
Push create button and set characteristics.
Set Priority, the Characteristic Values and the Protected Quantity
Push Create button and set characteristics if you use Prioritized Characteristics.
And set protected Quantities for each period.
Push Create button.
Push Activate button.
Create Other Supply Protection objects for other Sales Offices as well in this case.
Case: no Prioritized Characteristics
Set protection group values
Finally I created 3 supply protection objects
Execute “Create Sales Orders VA01” Fiori Apps.
Set Sales Order Type, Sales Area and Sales Office.
Set sold-to party and Customer reference number.
Set material number and quantity.
Push enter key.
Then “Review Availability Check” (Only for Fiori Apps”Create Sales Orders VA01″ From OP2021) screen appears, in this case confirmed quantity is 950 pcs. Push “>” button.
Then, click “Intermediate Results”.
Click “Show Details for Supply Protection”
You can see “Review Supply Protection Check Result”.
Because confirmed quantity for Sales Office 170 and Customer Group 01 Sales Order
3000(inventory)- 1050(Sales Office 17A) – 1000(17B) = 950 pcs
Because confirmed quantity for Sales Office 170 and Customer Group 02 Sales Order
3000(inventory) – 500(170 & Customer Group 01) – 1050(Sales Office 17A) – 1000(17B) = 450 pcs
Because confirmed quantity for Sales Office 170 and Customer Group 03 Sales Order
3000(inventory) – 500(170 & Customer Group 01) – 500(17A & Customer Group 02) – 1050(Sales Office 17A) – 1000(17B) = – 50 pcs
So, confirmed quantity is zero.
Supply protection protects related supply protection object total quantity. It defines minimum quantities. So, If every related supply protection objects total quantities can be kept, confirmed quantity is no upper limit until whole inventory consumed.
If you want to set upper limit, use the below “Production Allocation(PAL)”.
Integration into Other Advanced ATP solution
Product Allocation (PAL)
Supply protection and product allocation (PAL) are complementary solutions. While with PAL an upper limit is defined, the logic of supply protection defines minimum quantities. For more information, see Avoiding Matches with Multiple Protection Groups.

Great Blog! Thanks for sharing.
Thanks for sharing the insights. It looks great.
I have few questions.
Supply Protection is a virtual demand restriction the availably stock dependent on the characteristics of the demand. If there is enough stock available, nobody will notice that supply protection is maintained. In other words a customer can get any quantity of the stock as long as there is enough left for the once which are protected.
Just a very simple example.
There is Supply Protection of 1000 for a customer-group A. The total stock for this material-plant combination is 10.000. This means that a customer not belonging to group A could get a quantity of 9.000 (= Stock minus restriction).
If a customer of group A was first, this customer could get 10.000.
If B was first and orders 9.000 only 1.000 are remaining. In this case only customers of group A could get the 1000.
Thanks for sharing, I have a quick doubt regarding the protected quantity.
Here it shows that system is protecting 500 nos though we have maintained the split week wise. So what is the actual requirement for us to plan on a weekly manner. We can just maintain a constant value to be protected.
I have a similar question in relation to the time buckets.
Are the time buckets only there to auto expire the unused protected quantities, if there are buckets in the future the total quantity still needs to be protected even though the sales order MAD falls outside the range of the protection object?
thanks in advance
The online help says "If the protection of a time bucket is not completely consumed, it will expire once it is in the past."
