What is SAP Customer Order Sourcing?

SAP Customer Order Sourcing is a public cloud service based on SAP Cloud Platform and offers

• Calculation of (omnichannel) product availability
  • across DC’s, vendors, 3rd party warehouses and even stores
  • You can use APIs to upload availability raw data. Based on this data and on temporary reservations, the system calculates which products are available to sell and in what quantity across all source types such as stores or distribution centers.
• Management of sources and source lists
  • You can use APIs to upload, retrieve, and delete sources and their master data, and group sources in source lists. Sources and source lists are used for modeling sourcing strategies. You can also create source lists in the Strategy Builder app.
• Creation and maintenance of sourcing strategies
  • You can use the Strategy Builder app to model sourcing strategies. Sourcing strategies can be assigned to your Web shop, for example, and are the basis for sourcing runs.
    
• Calculation of optimal sourcing results
  • You can use APIs to calculate a sourcing result for one or multiple products with specific identifiers. When it calculates the sourcing result, the system runs through the assigned sourcing strategy.
• Management of temporary reservations
  • You can use APIs to create, retrieve, update, and delete temporary reservations used to reserve products for a customer who is in the checkout process to buy the products. These reservations prevent the same product from being promised to different customers.

What you will learn in this blog post (no coding required)

• You will be introduced to SAP Cloud Platform Cockpit and Subscribe to SAP Customer Order Sourcing (Trial).
• You will use SAP API Business Hub to upload master data ¹ via REST API of SAP Customer Order Sourcing Service
• You will model your first sourcing strategy via the Strategy Builder App of SAP Customer Order Sourcing Service.
• You will create a sourcing request to test your sourcing strategy.

¹ What are the required master data for SAP Customer Order Sourcing?

SAP Customer Order Sourcing needs to know which and how many of a product are available (we call it availability raw data) in which locations (we call it sources).
These data are used for further calculations concerning:

• Available products to sell
• Sourcing result for products
• Reservation of products for a certain period of time

For a better understanding of SAP Customer Order Sourcing, let’s have a look at the following, very simplified Business Scenario:

You are the owner of an E-Commerce (or web shop owner) Business in the Fashion Industry with these characteristics (which is the required master data for the service):

• sources: you have one Store in Stuttgart and one Distribution Center (DC) in Munich
• availability raw data: You only have one product available with the following quantity:

As a Business Owner you want to reduce delivery cost of each order and therefore decide for the following Sourcing Strategy:

“The products in the shopping cart should be delivered from the source with the shortest distance to the customer.”

For instance:

• A Customer located near Stuttgart, ordering a Red_T-shirt, should be supplied from the Store in Stuttgart.
• A Customer located near Munich, ordering a Red_T-shirt, should be supplied from the DC in Munich.

1. Open your global account in the Cockpit.
2. Navigate to Global Accounts and your Subaccount named trial.
3. In the navigation area of the trial subaccount, choose Subscriptions.

2. Insert a Strategy ID with the id “my-webshop-strategy-de” (you will need it later) and a display name, for example, “My sourcing Strategy for web shop in Germany”.
3. Choose Create to finish the creation of your first strategy.
4. Choose the newly created strategy from the Sourcing Strategies list, to build a specific strategy.

1. Go back to your cloud Cockpit > Cloud Foundry Trial > Trial > Spaces > Your Space > Services > Service Marketplace
2. Choose SAP Customer Order Sourcing (Trial) and navigate to the Service Overview.
3. On the left side bar navigate to Instances > New Instance ( )

Step 3.1: Upload sources

1. 1. On the left side choose Sources
   2. Open POST /sources and choose try out.
   3. Copy the following sources data and paste it into the body:

[{  "sourceId": "munich_dc",
        "sourceName": "Munich Distribution Center",
        "sourceType": "DC",
        "sourceCoordinates": { "latitude": 48.136781, "longitude": 11.577352 }
},
{  "sourceId": "stuttgart_store",
    "sourceName": "Stuttgart Store",
    "sourceType": "STORE",
    "sourceCoordinates": { "latitude": 48.774247, "longitude": 9.181072 }
}]

1. 4. Click execute.
   5. Make sure you get the HTTP response 201.

Step 3.2: Upload Availability Raw data

1. 1. On the left side choose Availability Raw Data.
   2. Open POST/availabilityRawData and choose try out.
   3. Copy the following availability raw data and paste it into the body:

[{  "productId": "Red_T-shirt",
    "unit": "C62",
    "calculatedAt": "2019-09-24T21:54:30Z",
    "items": [ { "availableFrom": "2019-09-24T00:00:00Z","quantity": 4 } ],
    "source": { "sourceId": "stuttgart_store", "sourceType": "STORE" }
},
{   "productId": "Red_T-shirt",
    "unit": "C62",
    "calculatedAt": "2019-09-24T21:54:30Z",
    "items": [ { "availableFrom": "2019-09-24T00:00:00Z", "quantity": 11 } ],
    "source": { "sourceId": "munich_dc", "sourceType": "DC" }
}]

1. 1. Click execute.
   2. make sure you get the HTTP response 201.

1. Go back to Strategy Builder App and choose the Strategy my-webshop-strategy-de.
2. Drag and drop the Objective Products from Several Sources onto the canvas for modeling your strategy, under the shopping cart.
3. Drag and drop the Sources Munich Distribution Center (DC) and Store Stuttgart (Store) into the first box.
4. Drag and drop the Rule Shortest Distance to Destination into the second box.
5. Save your strategy.

Hint: The box where the building block is supposed to go is highlighted when you drag them onto the canvas.

The modelled strategy says:

For a sourcing request with this Strategy:

1. Consider the sources in Munich and Stuttgart.
2. Source Products according to the rule Shortest Distance to Destination

In other words:

The products in the shopping cart should be delivered from the source with shortest distance to the customer.

Now let’s test our strategy

Scenario: A Customer Located close to Stuttgart orders a Red_T-shirt.

Desired Sourcing Result: Red_T-shirt should be sourced from Stuttgart since it is closer to the customer than Munich.

let’s check if this is the case

1. Open SAP Customer Order Sourcing on SAP API Business Hub in a new window.
2. On the left-hand side choose Sourcing.
3. Post the following sourcing request:

{ 
  "strategyId": "my-webshop-strategy-de",
  "items": [ { "productId": "Red_T-shirt", "quantity": 1 } ],
  "destinationCoordinates": { "latitude": 49.004417,"longitude": 8.400847 }
}

In the sourcing result you see that the Red_T-shirt should be sourced from stuttgart_store.

An optional task for you:

Create a sourcing request for this scenario to test your strategy:
Scenario: A Customer Located in Ingolstadt (latitude: 48.764472, longitude: 11.426090) orders 1 Red_T-shirt

Let us know in comments, how your sourcing request and your response looks like. Good Luck!
