About SAP
SAP is one of the most widely used ERP software for modern organizations around the world. SAP systems are key to centralized data management and for adding efficiency and automation to business processes. SAP ERP is modular, and organizations can choose from a wide range of modules, to pick the ones most relevant to their business. Earlier different departments of an organization would have data stored in separate databases, for e.g. inventory, sales, suppliers etc. and this data would not be easily accessible to users in other departments. SAP allows organizations to centralize the data, accelerate workflows, and to use it for business analytics to increase productivity. BryteFlow for SAP DB Replication
SAP solutions have evolved with the times and today they can be installed on-premise, on the Cloud or even as a hybrid implementation. SAP offers more than 100 products customized for various business applications. In addition, there is an ecosystem of SAP partner vendors and consultants who offer more products and services to customers. As you can see, SAP systems generate a lot of data, and it needs to be extracted and delivered from SAP internal and external systems to Cloud data warehouses and repositories for consumption. SAP connectors play a big role in this. About BryteFlow SAP Data Lake Builder
What are SAP Connectors?
SAP connectors provide the means for SAP systems to integrate with different applications and technologies by use of open standards. SAP connectors enable technical operations between SAP components, usually coded as ABAP or ABAP objects, with components typically coded in C++, Java, .NET, Visual Basic etc. SAP HANA to Snowflake (2 Easy Ways)
App Connect and the SAP instance can have bi-directional communication using the SAP connector. The connector supports BAPI (Business Application Programming Interface), RFC (Remote Function Call), and IDOC (Intermediate Document) interfaces. How to Carry Out a Successful SAP Cloud Migration
Types of SAP Connectors
SAP has 6 basic connectors that can enable exchange of data between various external systems and tech environments and SAP ABAP systems. RFC, HTTP and IDocs are the underlying supported technologies for two-way communication. SAP to Snowflake – Easy Integration
SAP connectors function in 2 ways:
Client Case Functionality
The external system executes functionality by sending inputs into the ABAP system and receives the results of the operation in the response. RISE with SAP (Everything You Need to Know)
Server Case Functionality
The ABAP system executes functionality by sending inputs to the external system and receives the results of the external operation in the response. SAP HANA to Snowflake (2 Easy Ways)
Here are some SAP Connectors we will touch upon.
SAP NetWeaver RFC Software Development Kit (NW RFC SDK)
If it is possible to extend the external system with C/C++ coding, the NW RFC SDK is an ideal connector. It also provides bindings for other programming languages, with a native C interface, like Perl, Python, PHP or Go. It supports communication via RFC and WebSocket RFC.

Transferring data from SAP Oracle to SAP HANA DB with BryteFlow
For illustrative purposes, here is a step-by-step process to demonstrate how to move data from an SAP Oracle database to an SAP HANA database using BryteFlow Ingest. BryteFlow Ingest replicates data from SAP databases (provided you have access to the underlying database) while BryteFlow SAP Data Lake Builder delivers data from SAP applications. In either ase, you can move the data in just 5-6 steps.
Step 1: Download and Install BryteFlow Ingest. Login and Configure source database.
You have two options for obtaining the software: you can contact the BryteFlow team or download it from the AWS Marketplace or from the Azure Marketplace. Once it’s installed, log in and select the “Connections” link on the left panel. Select the ‘Source’ tab in the top nav bar. From there, follow these steps to set up your source database:
- Choose “SAP (Oracle)” as the Database Type.
- Enter the OracleHost Details in the Database Host field.
- Provide the Port Details in the Database Port field.
- Input the Database Details into the Database Name field.
- Enter the User Id used for Database connection in the User Id field.
- Input the corresponding User password for Database connection into the Password field.
Step 2: Configure destination database.
To establish a connection with your destination database, on the “Connections” screen select the “Destination” tab on the top nav. Follow these steps to set up the Destination Database.
- From the dropdown menu, choose “SAP HANA JDBC” as the Database Type.
- Specify the destination drive details within the “dst-drv” section.
- Input your destination URL into the “dst-url” field.
- Enter your user ID into the “User ID” field.
- Provide the corresponding user password for the database connection in the Password field. Please note that certain fields may differ depending on the source database selected.
Step 3: Select the tables you want to replicate.
Select the “Data” link in the left panel to set up the source table(s) for replication. Here, you’ll define the primary key and transfer method for each table. Opting for ‘By Primary key with History’ automatically maintains SCD Type2 history. Alternatively, selecting ‘By Primary Key’ creates a mirrored copy of the source table without historical records. Additionally, you can use the “Where” feature to filter out undesired data. Byteflow Ingest offers the capability to “mask” sensitive information within columns.
Step 4: Schedule the replication.
Select the “Schedule” link in the left panel to visit the Schedule page. Here you can schedule the data transfer. You can opt for either “Automatic” or “Periodic” replication of deltas. “Automatic will deliver deltas as soon as there are changes at source while “Periodic” option enables you to create your own schedule, whether daily or weekly.
On the right you have four buttons at the bottom of the screen. Select “Full Extract” for starting the initial load. Select “Sync New Tables” to incorporate new tables after replication activation. Select “Sync Struct” to reflect structural changes in existing tables. Select “Rollback” to return to a previously successful operation, especially useful in case of replication interruptions.
Step 5: Monitor the transfer of data.
Select the “Dashboard” link in the left panel to get insights into ongoing data transfers, such as the overall count of loaded records and tables, live updates on ongoing loading operations, replication intervals, and the current state of connections.
Note: As an alternative tracking option, select the “Log” link in the left panel to track data loading progress via the log, and get instant notifications about the data replication. This covers extraction or loading statuses, the volume of loaded records, and any errors encountered within the process.
