Building data models into SAP HANA

February 7, 2023

Pyramid is an official member of the SAP® PartnerEdge® open ecosystem and is fully certified by SAP on SAP BW/4HANA, SAP HANA, and SAP Netweaver. The Pyramid Platform is also available on the SAP Store.

SAP HANA is an in-memory, column-oriented, relational database management system ideal for handling large datasets. Reading and querying data from SAP HANA is common in most BI toolsets—albeit with varying degrees of functionality and analytical control.

But what about building new data models (and data mashups) and “writing” them back to HANA as a target system?

The problem

Enriched data is of great value to end-users. It provides enhanced context for deeper analysis or categorization of existing data. Indeed, many machine learning processes involve adding new elements to a data set for further analysis or use. In processing such data—either cleaning it, embellishing it, or attaching new data to it—users need a place to store the processed outcome. Unfortunately, almost all BI tools (such as Power BI, Qlik, and Tableau) can only model and mash up data into their own proprietary data engines. They cannot write data back to other target systems—including SAP HANA.

While there are scenarios where this is not required, enterprises often prefer to have all data models hosted in the same enterprise technology stack rather than in siloed peripheral tools. This promotes reusability and data governance, and it allows the data assets of the enterprise to be secured and monitored.

The solution

Pyramid provides a visual, intuitive front-end tool where users can create their own data model by dragging and dropping their data sources onto a canvas. They can then perform both simple and complex data manipulations, machine learning, and AI functions by using ready-built functions, by building complex functions with point-and-click simplicity, or alternatively using pre-existing R or Python code.

The big difference is that Pyramid can use HANA as a data target where the resultant data set may be stored when the data flow process finishes. In fact, Pyramid may be one of the simplest ways to build or adjust a HANA database!

Business case

Angie is the CIO of Cornerstone Bank, an international bank specializing in personal loans. Cornerstone has an SAP HANA database and is looking for a BI system that will implement the specialized Python scripts, machine learning, and other scripts that are used to classify risk and market profiles associated with each applicant. After running a proof of concept (POC) with several vendors, it has become apparent that results from the machine-learning processes must be written back to the original SAP HANA data source. Without this functionality, data would have to be loaded onto another in-memory database, making the SAP HANA database partially redundant. In addition, unless this calculated data is materialized in the database, it must either be recalculated every time it is required (a massive, time-consuming task that doesn’t work).

Angie’s team decides to use Pyramid because it can process data from HANA, run the machine learning logic in Python, and then store the results back into HANA for analysis and reporting—all via the business user-friendly tools.

Machine learning data model

In the diagram below, Angie has used Pyramid’s self-service data modeling module. She has created a model where the SAP HANA database is accessed as a source. Various SAP HANA tables are selected, data is mashed together with an Excel source, a Python machine learning script is applied, and most importantly, the resultant data sets—using all the complex machine learning scripts—are stored on SAP HANA.

The Python script is used to predict the loan status for the next month. Existing data fields are used as inputs into the Python script detailing loan amount, interest rate, previous defaults, net monthly income, et cetera, producing a “Predict_Success” column where a value of 0 predicts a successful collection of the monthly loan repayment and a value of 1 predicts an unsuccessful collection.

  1. SAP HANA Database is used as a data source. Data is also sourced from Excel and is mashed together in the data model.
  2. Python code is used to predict the successful collection of monthly premiums.
  3. A preview displays the “Predict_Success” column that indicates the likelihood of a successful collection.
  4. Results are written directly to tables on the SAP HANA database.

Using Pyramid, Angie runs the model and processes 10 million records in 5 minutes. With the resultant data now immediately available in SAP HANA, all subsequent reports can be run without recalculating and reloading them into a third-party database. Using Pyramid’s powerful scheduling tool, the model has been scheduled to run every Monday morning at 3:00 a.m. The availability of this feature has made Angie’s job much easier. She can now leverage the organization’s large SAP HANA investment without needing to invest in a new replicated in-memory data source.


In this blog, I have discussed Pyramid’s ability to write data back into SAP HANA through a business-user-focused data ETL and modeling tool. It allows end-users to run Python scripts, machine learning code, and other data manipulations to build new data values and write the results into the SAP HANA.
