SAP order to cash accelerator

The SAP accelerator for the order to cash process is a sample implementation of the SAP Table Batch Source feature in Cloud Data Fusion. The accelerator helps you get started when you create your end-to-end order to cash process and analytics. It includes sample Cloud Data Fusion pipelines that you can configure to perform the following tasks:

  • Connect to your SAP data source.
  • Perform transformations on your data in Cloud Data Fusion.
  • Store your data in BigQuery.
  • Set up analytics in Looker. This includes dashboards and an ML model, where you can define the key performance indicators (KPIs) for your order to cash process.

This guide describes the sample implementation, and how you can get started with your configurations.

The accelerator is available in Cloud Data Fusion environments running in version 6.3.0 and above.

Sample datasets in BigQuery

In the sample implementation in this accelerator, the following datasets are created in BigQuery.

Dataset name Description
sap_cdf_staging Contains all the tables from the SAP Source system as identified for that business process.
sap_cdf_dimension Contains the key dimension entities like Customer Dimension and Material Dimension.
sap_cdf_fact Contains the fact tables generated from the pipeline.

Sample pipelines in Cloud Data Fusion

Sample pipelines for this accelerator are available in the Cloud Data Fusion Hub.

To get the sample pipelines from the Hub:

  1. In the Cloud Console, open the Instances page.
    Go to Cloud Data Fusion Instances
  2. In the instance Actions column, click View instance.
  3. In the Cloud Data Fusion web UI, click Hub.
  4. Select the SAP tab.
  5. Select Pipelines. A page of sample pipelines opens.
  6. Select the desired pipelines to download them.

Each of the pipelines contains macros that you can configure to run in your environment.

There are three types of sample pipelines:

  • Staging layer pipelines: The staging dataset in this type of pipeline is a direct mapping to the original source table in SAP. The sample staging layer pipelines have names that refer to the SAP source table and the BigQuery target table. For example, a pipeline named KNA1_Customer_Master refers to the SAP Source Table (KNA1) and BigQuery target table (CustomerMaster).
  • Dimension layer pipelines: The dimension layer dataset in this type of pipeline is a curated and refined version of the staging dataset that creates the dimension and facts needed for the analysis. The sample pipelines have names that refer to the target entity in the target BigQuery dataset. For example, a pipeline called customer_dimension refers to the Customer Dimension entity in the BigQuery dataset sap_cdf_fact.
  • Fact layer pipelines: The fact layer dataset is a curated and refined version of the staging dataset that creates the facts that are necessary for the analysis. These sample pipelines have names that refer to the target entity in the target BigQuery dataset. For example, a pipeline called sales_order_fact delivers curated data to the Sales Order Fact entity in the corresponding BigQuery dataset sap_cdf_fact.

The following sections summarize how to get the pipelines to work in your environment.

Configure staging layer pipelines

There are two configuration steps for the staging pipelines:

  1. Configure the source SAP system.
  2. Configure the target BigQuery dataset and table.

Sample pipelines used for order to cash KPIs

The following key business entities in the order to cash process correspond with sample pipelines in the accelerator. These pipelines deliver the data that powers the analytics about these entities.

Key business entities Corresponding sample pipeline name
A Customer might be a person or an entity with whom the organization does business. These three SAP source tables capture details about the customer as they pertain to the business. Information from these tables contributes to the customer_dimension in the sap_cdf_dimension dataset. KNA1_CustomerMaster
Material is the commodity that is traded between the enterprise and its customers. Information from these SAP source tables contributes to the material_dimension in the sap_cdf_dimension dataset. MARA_MaterialMaster
The order management sub-process of the order to cash process (when your system receives an order from the customer). VBAK_SalesDocumentHeader
The order fulfillment and shipping sub-processes. LIKP_DeliveryHeader
The invoicing and customer payments sub-processes (when the customer receives an invoice). VBRK_BillingHeader

Configure dimensional layer pipelines

You can extract KPIs from source SAP tables. To prepare the data for analysis, organize the data in the source table to match the BigQuery table's schema structure.

The accelerator creates the following four sample tables:

Table name Table description
customer_dimension Curated list* of Customers and their associated facts such as customer classification, customer hierarchy, and customer sales-related information.
material_dimension Curated list of Materials and associated facts such as SKU number, product hierarchy, and classification.
sales_order_fact Curated list of sales information such as order types, order status visibility, ordered quantity, and order value. These fields are typically aggregated to generate order management KPIs such as Open Orders, Confirmed Orders, Rejected Orders, and Billed Orders.
revenue_fact Detailed accounting information generated by the Sale of the Material to Customers. Derived from the Accounting tables, this fact table contains information that can provide insights through Revenue KPIs including Gross Sales, Net Sales Before Discount, Net Sales After Discount, or Trends.

*In this context, the curated list comes from business logic that gets applied to the selected list of columns.

The accelerator builds the dimensional layer of the BigQuery dataset using SQL scripts, which you can modify for your project. For example, you can adapt these scripts to add more columns to the target BigQuery dataset entities.

Transformation to star schema: BigQuery executor pipeline names

The following BigQuery executor pipelines in Cloud Data Fusion load data into dimension and fact tables:
