Calculation Engine Plan Operators (CE Functions) Vs SQL Code

In this blog, I’m going explain few CE Functions and also the alternative solution for CE Functions using three tables with sample data.

The reason why I’m talking about this topic is, still some people are thinking about CE Functions, so I just want to clear the myths about CE Functions. CE Functions are alternative to SQL Script. We have total 13 CE Functions, but out of 13 , we may need CE_VERTICAL_UNION CE Function (this is used to combine the columns of different tables though they don’t have any relation), because we don’t have simple alternative solution in SQL.

Use of Segmentation in S/4 HANA for Product Revisions

With S/4 HANA, SAP introduced a concept called Segmentation that was available in an Industry Solution prior to S/4 HANA. This blog provides an overview of how Segmentation can be used to track product revision levels with segregation of inventory for each of those revision levels.

In a B2B world, usually a product is assigned a new identification (new part#/material#) if there is a change to the form/fit/function. But if the change is minor (no change in form/fit/function), the customer assigns a revision level and may specify that product revisions are not interchangeable. One solution to solve this business requirement is Segmentation within S4/HANA that works throughout the supply chain. Segmentation can be used to assign revision levels and track these revisions (Inventory, Demand, Supply at these revision levels) throughout the logistics processes from Sales/ Procurement/ Manufacturing and Inventory.

SAP Data Services – Defining delta using hash functions

In section 34 Changed Data Capture of the SAP Data Services Designer Guide you can find a very good description of the various delta load capabilities in SAP Data Services. Isn’t that worth an attentive read?

Delta loads are commonly used to reduce overall ETL processing time. When the number of new and modified source records is relatively low compared to the full data size, overall performance will increase significantly. Not only the time spent in extraction will be much lower, also the transformation and load steps will run much faster because those operations will apply to a (minor) subset of data only.

Integrating SAP HANA XSA with Microsoft Office 365 Sharepoint Excel using Microsoft Graph API and NodeJS

I would like to show how to read data from Microsoft Office 365 using Microsoft Graph API and NodeJS and then write this data into SAP HANA XSA tables.  Our scenario requirement was to pull data from Excel files on Sharepoint on Microsoft Office 365 and write this data to SAP HANA XSA container tables.  We wanted to use the SAP HANA File Adapter which has a section for Sharepoint Configuration.  However, the Excel adapter as of HANA 2.0 SPS 3 can only connect to Sharepoint 2013 on premise systems and not Sharepoint on the Microsoft Office 365 Cloud.  So we had to come up with an approach to address this requirement and develop it.  This Blog describes the approach which will hopefully help other folks needing to accomplish this type of scenarios for integrating Microsoft Office 365 data with SAP HANA XSA .  There will be another Blog that describes how to trigger our custom developed NodeJS application from a virtual procedure through the file adapter through SAP HANA Smart Data Integration (SDI) layer.

Motivation


When establishing an Enterprise Data Warehouse (EDW) there are two fundamental approaches which can be taken. Either an application driven approach can be chosen by opting for a solution which covers all tasks to be performed in an EDW out-of-the-box or the data modelling is natively performed directly on the database with a collection of separate tools to support the deployment and operations of an EDW.

Smart Data Integration: Write Back to MS SQL Server

Prio 1 Use case for SDI is the Table Replication from a non-SAP Data- source into SAP HANA tables. For some Data- sources it is also supported to not only read data from it, it is also supported to write back to it.

Meaning having SAP HANA content as source and writing the Data into the 3rd Party Data- source. Source could be a table or a, even BW generated, Calculation View.
