Master Data plays an important role in any SAP solution.With master data, businesses maintain central view of mission-critical data and teams that need these records execute their business functions based on the same information. Without having access to master data, information begins to fall out of sync between departments.

When customer is having very huge landscape of SAP systems including both S/4 HANA and ECC systems importing of Master Data( Business Partner and Products) becomes the tedious job and there can be Coex scenarios as well.

You can use the Data Replication Framework (DRF) to replicate master data such as business partners, products, and locations between source systems and target systems. The DRF uses a Key Mapping Framework to map the IDs of the corresponding objects in the source and the target system when replicating master data.

Since customers are widely using the DRF framework to transfer their master data between on premise systems same can be used to transfer the master data to SAP BTP applications as well.

The support of the middle wear might be required based on the need if your BTP application is not importing the data as it is.

In this blog I am explaining the steps which is carried out replicate both Business Partner and Product master data into SAP BTP offering SAP Returnable Packaging Management.  The blog covers  how to  configure the business systems to transfer the data and configure the replication models, middle wear configurations etc.

Business Partner Replication from S/4 HANA On Premise

5) Configuring Filter Values

a. Go to the transaction: DRFF

b. In the browser, select the relevant Replication Model and click Change.

c . Add the desired filters and save them.

Create Outbound Services for data replication (SOAMANAGER)

Below are the different objects used in the SOAMANAGER screen.

1. Start the transaction SOAMANAGER.

2. Choose Web Service Configuration under Service Administration.

3. Search for the following mentioned object names one after the other and repeat the below-mentioned procedure

4. Click Create and Choose Manual Configuration.

a. Under Logical Port Name

Enter the logical port name, for example, LP_<System name that you are connecting to>. ex: RPM_CPI_LP

Choose Logical port in the Default check box.

Enter the description, for example, <For Business Partner Data Replication>.

Choose Next.

b. Under Consumer Security

For Basic Authentication:

In case the Authorization type is User Role in your integration flow, choose the User ID/Password option, and enter the SAP Cloud Platform integration User ID and password to connect to the SAP Cloud Platform Integration tenant.

In case the Authorization type is Client Certificate for your Sender configuration in the integration flow, choose X.509 SSL Client Certificate for Authentication Settings. Then choose an item for your SSL Client PSE of transaction TRUST.

Choose Next.

c. Messaging

d.Under Transport Settings

Enter CPI operation server/worker node URL in the URL field – https://c2812-iflmap.hcisb.int.sap.eu2.hana.ondemand.com/cxf/BusinessPartner

Choose Next.

e. Repeat the same procedure for CO_MDG_BP_RPLCTRQ with the URL to be entered as (same as above in step 4), if you use the same integration flow to receive Business Partner Relationship payload.

SAP CPI

Create a new Iflow to make all the mappings between the S/4 HANA payload and RPM BP entity.

Click on the package. Go to the Artifacts tab. Then select and click on “Replicate Business Partner from backend to RPM” to open.

Click on edit to make changes to the iflow. Then Save it.

Click on Configure to change the configurations of the sender (S/4 HANA) and receiver (RPM).

Select Sender to configure S/4 HANA details. Make sure the below values are present. Authorization: UserRole is used here as we have used Basic Authentication in SOA MANAGER configurations above. Change to Client Certificate if it is used for Authentication between S/4 HANA and CPI.

Go to Receiver to configure the RPM API URL. Provide the details below and save them.

We have used Authentication OAUTH Client credentials to access RPM APIs.

Add the already created Credentials artifact under the Credentials Name field. Check below for creating a Credential artifact.

Create the Credentials using the following steps –

Click on the eye symbol in the navigation and then select “security material” under the “Manage Security Material” section.

Then click on Create and enter details to create new credentials artifact.  The name provided here should be used in the above section

Then deploy the artifact.

Iflow Deployment :

• After providing all the above details, deploy the iflow.
• Check the iflow deployment status by following the below steps –
  • Click on the eye symbol in the navigation and click on the below-highlighted box

Search the iflow by providing the name below. Check if it has deployed successfully. fix if there are any errors and re-deploy.

Find the iflow url under the endpoints section and this URL is configured in the SOAMANAGER – under the Transport Settings tab URL field.

Trigger the BP Replication

• Login to the S/4 HANA system using SAP GUI.
• Go to transaction BP and search for a BP. Update any field and save the record.
• It will automatically trigger an outbound message to CPI.
• Check CPI for BP in the messages.
• Then trigger the GET BP API from the postman (attached collection below) or check the BP in RPM UI.

Manual Replication :

Go to transaction DRFOUT. Select the replication model (created in the starting) and outbound implementation (986_3) for BP.

Select/Enter the values in Manual Replication Filter Criteria. Save it. Then click on F8 to execute the transaction. 

Troubleshooting :

• Check transaction “SRT_MONI” for the status of outbound messages. This will help to fix if there are any errors in the processing.
• The business System should be configured in the SLD system before using it in DRFIMG Configurations
• Make sure the USER ROLE in the iflow is configured to ESBMessaging.send if user credentials are provided in SOAMANAGER.
• Download the WSDL files of respective objects from S/4 and upload them in the iflow→message mappings section before mapping source to destinations fields in Iflow.
