Core Data Services [CDS] in SAP S/4 HANA

A data model represents framework of what relationships are in a database. Data models are the foundation of software development. They provide a standardized method for defining and formatting database contents consistently across systems, enabling different applications to share the same data.
Professional data modeling tools provide a way to generate SQL from a modeled ER diagram although some developers often prefer writing SQL directly. Below is a look of a data model.

Hana DR – Replication of INI parameters

Before Hana SPS12 we always have to manually setup the INI parameters on the secondary site after a change in the primary. It is not a tough thing to do nevertheless SPS12 introduced a feature to get a synchronization between the systems in a DR scenario also for INI parameter changes. One more step in the Hana synchronization and in my opinion it’s welcome.

I’ll not go into the replication configuration steps just describe my findings on the INI replication subject. Hope you get it useful.

S/4 HANA Trial Balance CDS View

We were very excited when we discovered the standard SAP delivered CDS C_TRIALBALANCEQ0001 for displaying the Trial Balance as the calculation of opening and closing balances can be tricky and the Universal Journal ACDOCA table was new to us, as was S/4 HANA.

During our testing using the embedded BW we realised that the opening and closing balances it was returning was incorrect and upon consultation with SAP they confirmed that additional new Fiscal configuration is required on an S/4 HANA environment.

SAP HANA Security: Granting Object Privileges with Repository Roles

This blog explains how to use the SAP HANA Web-Based Development Workbench to grant object privileges with repository roles in SAP HANA.

SAP HANA Web-Based Development Workbench

The SAP HANA Web-Based Development Workbench editor, hosted within the XS engine, provides an interface that you can use to build and test development artifacts. From a security perspective, we can use this interface to create and manage repository-based roles. This interface offers all the advantages of repository-based roles without the need to define those roles using scripts. The interface is not exclusive, meaning that you can edit repository-based roles created using scripts with the GUI interface, and you can edit a repository-based role’s scripts, those created using a GUI, in SAP HANA Studio. This flexibility allows the security administrator to manage the repository role using either interface.

Consuming SAP HANA Express Edition information models in Microsoft Power BI using live connection

Initially I created my account at https://powerbi.microsoft.com. I also subscribed for the Microsoft Power BI YouTube channel.

so, I decided to play around connecting Power BI with my SAP HXE instance. Generally speaking there are two ways of connecting and consuming SAP HANA information models in Power BI: Import and DirectQuery. For this post, I will be showing my SAP HANA live data connection with Power BI (DirectQuery).

HANA Deep Insert

I have been very impressed with HANA and the ease in which you can expose an OData service for your entities and views. Since starting work on the platform I have found the need to store my entities using a deep insert. I thought surely this was possible, but like many I have been disappointed to find that this is not supported.

Currently the solution to this problem is to place the creates into a batch in the front end. My main issue with this is the parent Id is not returned to me to place into the child objects. I am then forced to place the child create in the success handler of the parent object create, losing the transaction functionality.

SAP HANA Multitenant Database Containers (MDC) Features Chart

Starting from HANA 2.0 SPS01, Multitenant Database Containers (MDC) will be the standard and only operational mode for SAP HANA systems, and definitely one of the significant changes that will have greater influence, affect directly or indirectly on customers’ systems that are currently running on single container but plan to update to HANA 2.0 SPS01+ and above anytime soon or in near future.

Want to know the differences and the developed of MDC with more supported features and less limitations compare to years ago when it first introduced on HANA 1.0 SPS09+ ?

Avoiding HANA Enterprise Cloud Headaches!

A source told me that one of the largest SAP customers in the (ANZ) region is moving from HANA Enterprise Cloud (HEC) back to an on-premise infrastructure model. Well, this was not surprising for me as I already knew some customers in Europe also moved from HEC to on-premise or other cloud offerings, due to unexpected and unforeseen issues with the HEC model.

I am aware that the majority of the businesses still can’t simply justify the business case for HEC, and it is disappointing to see that some existing customers don’t get the expected business benefits from this model.

Restore SingleDB on 122.08 to Multi Tenant DB on HANA 2.0 SPS01

Just tested recover a single Database to Multi Tenant Database without the need to convert them to MDC beforehand with below scenario and thought it is a good idea to share.

This enhancement only work on target >= HANA 2.0 SPS01 and is particularly useful where it keeps your source/ productive database intact and allows you to to perform a series of testing before converting them to MDC, especially if you plan to upgrade to HANA 2.0 SPS01 since MDC would be the standard and only operation mode.

HANA Backup and Recovery: Multi-streaming Data Backups with Third-Party Backup Tools

SAP HANA uses one channel for data backups, by default. With the introduction of SAP HANA SP11 we have new functionality available to make it possible to considerably speed up the backup time by distributing backup data in parallel to multiple devices by using third party back-up tools.

When multiple channels are used, SAP HANA distributes the data equally across the available channels. All the parts of a multi-streamed backup are approximately the same.

SAP HANA High Availability and Disaster Recovery Series

My purpose is to deep-dive into the entire SAP HANA high availability (HA), fault recovery (FR) and disaster recovery (DR) concept including the high-level overview of ALL available HA, FR and DR options, different configuration and setup methods and key benefits and trade-offs of each technology. I aim to provide deeper, clear and broader information in SAP HANA HA and DR technologies unlike the majority of confusing and contradictory information available on the internet. At the end of the day, you will be able to compare all available DR, FR and HA options, learn how to ensure your system’s operational continuity and decide the most suitable approach for your own data center readiness scenario to meet the business requirements.

A short overview of the SAP HANA Performance Management Tools in SAP HANA 2.0 SPS00

SAP HANA capture and replay


Testing application workload can be a huge effort for users, developers and consultants alike. Also, things do not get easier on a large scale, especially for moving from one revision or SPS of SAP HANA to another.

Initially released with SAP HANA1 SPS12, SAP HANA capture and replay offers semi-automated support for integrated testing in the context of SAP HANA., the goal being to simplify the manual effort needed for creating tests and performing a more accurate replays than what is possible with other approaches.
