Have you ever encountered issues with enqueue locks or drafts that were not removed automatically?
We recently faced exactly this situation in one of our systems and were finally able to identify the root cause and resolve the issue.
Draft data is persisted in the draft tables of
This year (2026), at a BW/4HANA customer: brand-new transformation routines in ABAP, cleanly formatted, modern syntax in many places. And right in the middle of it, a READ TABLE ... BINARY SEARCH. Written by a developer who was so young that BINARY SEARCH was already outdated when he was born. W
The CDS View Entities are currently celebrating their 5th birthday. On September 2, 2020 I found the first blog post [A new generation of CDS Views: CDS view entities](https://community.sap.com/t5/application-development-and-automation-blog-posts/a-new-generation-of-cds-views-cd

The cover picture of the article symbolises the day: HANA Tech Night is celebrating its 10th birthday. And as with every HTN, there will be pizza and beer. But not only...
A brief look back at SAP CodeJam and the 10th HANA Tech Night, both held on 3 June in Mannheim. It was a really suc

These AMDP programming guidelines are a proposal for ABAP and SAP BW projects. They were originally written for the use case of AMDP transformation routines in SAP BW/4HANA. Feel free to copy, modify and use them in your own projects as long as this article is linked as the source.
You will often encounter GUID and UUID in SAP HANA and in S/4HANA as key fields. As long as these do not have to be interpreted or converted, this is not a problem for SAP HANA. The prerequisite for this is a uniform data type. But there are different formats for UUID.
In this blog post, I would like to share a small example of an AMDP [aka. HANA Script or AMDP Script ((Actually there is no HANA Script or AMDP Script. These terms can only be found in the SAP BW environment in the Transformations. This neologism is a mixture of the te

CDS queries can only read data from CDS InfoProviders
Reporting directly in the transactional ERP system (e.g. S/4HANA) using CDS Views is called Embedded Analytics. Here, the CDS Q
The CDS InfoProvider Views form a modeling layer that serves as the starting point for Embedded Analytics in S/4HANA with CDS queries. However, the CDS InfoProviders can also be used directly as a source for queries in the Query Builder of the SAP BW M
Unfortunately, in the official SAP documentation there is no clear definition of designations to the CDS View types concerning their specific tasks and roles in the different frameworks . The articles and books in this area sometimes use different definitions here. For example, consumption v

Officially, the 2nd edition of SQLScript for SAP HANA, the English edition of my book, has been available since mid-August. Today I received my author copies from SAP PRESS and for the first time I am holding a bound copy in my hand. The format has become slightly large
The HANA Web-Console (HWC) from Brandeis Consulting is the quick entry into SQLScript programming on the SAP HANA database. For trainings and also for the daily work with SQLScript it is very practical, if you don't have to start the SAP
The 2nd edition of the English edition of SQLScript for SAP HANA is scheduled for release on August 26, 2021. The issue is updated and expanded with a few new topics. It thus largely corresponds to the current German edition.
The two SAP programming languages ABAP and SQLScript (aka. HANA SQL) behave differently when it comes to processing strings with blanks. This can lead to errors and confusion. It is therefore important to understand the ABAP VARCHAR mode o
SAP has unfortunately decided to stop making its VM images of the free HANA Express , which were previously available in the cloud from hyperscalers, available. So far, I have been a fan of HANA Express systems in Google Cloud Platform (GCP

With the ABAP Managed Database Procedures, or AMDP for short, SAP succeeds in making the performance of the SAP HANA database in ABAP developments easy to use. This is a framework that now includes not only SQLScript procedures, but also functions and also allows the
With SQLScript, errors can be avoided elegantly and performantly during loading due to the unallowed (i.e. invalid) characters in SAP BW. This article provides an overview of the problem and outlines the solutions in AMDP transformation routines to clean up the data.
When loading data from source systems, there are requirements in SAP BW that are often repeated at the field level. This includes, above all, logics for cleaning up and processing the data, such as:
The Neo environment of the SAP Cloud Platform will be switched off on November 14th! This also means that a popular opportunity to create a HANA instance with SQL console is disappearing...
Next week will be followed by a blog post on how to achieve this in the Cloud Foundry environment.

With version 2.0 SPS04 of the SAP HANA database, the so-called "End-User Test Framework in SQLScript" was introduced. This makes it possible to create SQLScript Unit tests in the form of [User Defined Libraries (UDL).](/en/blog/user-defined-libraries-udl-in-sqlscript
SAP HANA 2.0 SPS03 introduced the concept of User Defined Libraries (UDL) in SQLScript. It enables us as developers to bundle several functions, procedures and variables in one object. All components of a UDL are defined in one piece of source code and only one metada
With SAP HANA 2.0 SPS04, another feature has been added to the SQLScript language: The embedded functions. These enable the use of imperative SQLScript code within a SELECT query. These functions are created and executed only for exactly this one query. This r
Up to SAP HANA 2.0 SPS03 recursive calls in SQLScript were not allowed. This means that a procedure may not call itself either directly or indirectly via other procedures. This restriction was removed with SPS04. However, the call depth is limited to 32 and procedures
With BW/4HANA 2.0 I observed that the packet size of the DTPs is dynamically suggested by the system. Figure 1 shows, for example, a suggested size of 1,311,000 data records. In this way, the system dares to go into an order of scale, that is better than the former fixed standard value of 100,000 ro
BW/4HANA 2.0 no longer supports the administration of InfoProviders and requests in the SAP GUI. Instead, a browser window with the SAP BW/4HANA cockpit opens when we click on the administration of the ADSOs or start a DTP and the DTP monitor opens. You can find the SAP documentation for the B
In the SAP Cloud Appliance Library (CAL), you can use SAP's latest systems in the cloud with little effort. Some of the systems are free for certain purposes, and are great for learning new technologies. Especially the DEV systems can be used well for this purpose.
