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.

|Looker Developer||These users can install the Looker Block through the
They must have
Required IAM roles
In the accelerator's sample implementation, the following IAM roles are required. You might need additional roles if your project relies on other Google Cloud services.
- BigQuery Admin
- BigQuery Data Owner
- Storage Object Viewer
- Cloud Data Fusion Runner
roles/datafusion.runner) needs to be granted to the Dataproc service account
You can implement the accelerator in your project with the following steps:
- Configure the SAP ERP system and install the SAP transport provided.
- Set up your Cloud Data Fusion environment to use the SAP Table Batch Source plugin.
- Create datasets in BigQuery. The accelerator provides sample datasets for staging, dimensional, and fact tables.
- Configure the sample Cloud Data Fusion pipelines from the accelerator to integrate your SAP data.
- From the Cloud Data Fusion Hub, deploy the pipelines associated with the order to cash analytics process. These pipelines must be configured correctly to create the BigQuery dataset.
- Connect Looker to the BigQuery project.
- Install and deploy the Looker Block.

Sample datasets in BigQuery
In the sample implementation in this accelerator, the following datasets are created in BigQuery.
||Contains all the tables from the SAP Source system as identified for that business process.|
||Contains the key dimension entities like Customer Dimension and Material Dimension.|
||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:
- In the Cloud Console, open the Instances page.
Go to Cloud Data Fusion Instances
- In the instance Actions column, click View instance.
- In the Cloud Data Fusion web UI, click Hub.
- Select the SAP tab.
- Select Pipelines. A page of sample pipelines opens.
- 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 (
- 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
- 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
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:
- Configure the source SAP system.
- Configure the target BigQuery dataset and table.
Parameters for the SAP Table Batch Source plugin
The SAP Table Batch Source plugin reads the content of an SAP table or view. The accelerator provides the following macros, which you can modify to control your SAP connections centrally.
||SAP client to use||
||SAP logon language||
||SAP server name or IP address||
||SAP system number||
||SAP User name||For more information, see Using Secure Keys.|
||SAP user password||For more information, see Using Secure Keys.|
||Used to limit the number of extracted records.||
For more information, see Configuring the plugin.
Parameters for the BigQuery target
The accelerator provides the following macros for BigQuery targets.
BigQuery target connector configuration
||The project ID where the BigQuery dataset has been created.||
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|
|The order management sub-process of the order to cash process (when your system receives an order from the customer).||
|The order fulfillment and shipping sub-processes.||
|The invoicing and customer payments sub-processes (when the customer receives an invoice).||
|The accounts receivable and reporting sub-processes (when the payment is logged in your system).||ACDOCA_UniversalJournalItem|
All Cloud Data Fusion staging pipelines
The following Cloud Data Fusion staging pipeline samples are available in the accelerator:
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.

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