HANA Views & SQL – Technical Performance Optimization

BW on HANA can easily enable SQL data access for third party tools, using the “External SAP HANA View” flag to automatically generate Calculation Views out of BW objects. However, Consuming multidimensional BW scenarios through relational SQL paradigm can lead to quite some issues with performance. This blog is about a few basic technical tips, which help to enhance runtime performance. Tested with BW 7.5 on HANA SPS 10, 11 and 12.

Making use of an Active/Active (read only) HANA database in S/4 HANA

Introduction

At SAP, we thought about creating additional benefit for customers who run SAP S/4HANA on premise.

Many of them in fact run two SAP HANA databases in a SAP HANA system replication setup: the productive SAP HANA database (aka the primary SAP HANA database), and an additional ‘hot standby’ SAP HANA database (aka the secondary SAP HANA database). The latter is part of their high availability strategy and allows business continuity in case of a failure of the primary SAP HANA node.

Text join using pa0000 table in hana

I am sharing you concept called text join in HANA, which we mainly use to extract descriptive data from a table or language specific data from a table.

Text Join is used in order to get language-specific data.

Text Join is used to fetch the description based on user’s session language. Once we implement the text join in SAP HANA, it automatically find out user’s language and give description in that language.

Port Forwarding SAP HXE instance (VM) to allow connection from SAP BO 4.2 on the Cloud

In this post I will show you how I succeeded connecting SAP BO Platform 4.2 on the Cloud with my local SAP HXE instance (VM) for educational purposes only.

Scenario:

In my case, I do not have any of the SAP BI Client Tools, such as SAP BO IDT, SAP BO Webi Rich client, SAP Design Studio, and so forth installed on my devices. Reason is because I do not have authorization to download any software from SAP Download Center (which makes sense). So, my only gateway is the SAP BI Launchpad.

New Hana backup software

Hello, I would like to present a new backup software that we N’Ware Technologies have been developing to support our customer running on Hana.

We made this backup software because existing backup software were missing basic functionality or were complex to use.

linux Bash scripts/windows dos scripts to automate backups are complex to the normal user to manage. It requires specialized knowledge on how to use the command line, sometimes on linux that user might not know, and offer no other functionality than the basic 1 backup per day.

Calling HANA Stored Procedure from Abap class and scheduling it through Process chain (using AMDP – Abap managed database procedure)

This blog will explain below –
