Model Storage with Python Machine Learning Client for SAP HANA

Machine learning models, e.g. classification and regression model, contain the relationships and patterns between features in the training dataset which could be applied to similar data in the future for prediction. Model training could be time consuming, so it is desirable to store/persist a model for future use without retraining the model.

We provide a model storage class for model persistence, such as classification, regression, clustering and time series models. In this blog post, you will learn:

Migrating SAP Business One SQL Server to HANA

How to keep SAP Master Data Governance (MDG) customizing in sync with SAP ERP or SAP S/4HANA

Very often, SAP customers implementing SAP Master Data Governance (MDG) need to synchronize, at least, two customized systems in order to keep business processes that span across multiple systems consistent. In most cases, the customizing data are maintained on the operational SAP ERP or SAP S/4HANA system and distributed to the SAP MDG system.

Instead of doing the work manually in each system, you can automate this process. SAP Solution Manager offers two technical solutions for this:

SAP Business Application Studio – Using SAP HANA Tools with SAP Cloud Application Programming Model projects

In this blog post, I will show you how to add native HDB artifacts using SAP HANA tools to SAP Cloud Application Programming Model projects. We will start by creating an SAP Cloud Application Programming Model project, and then we will adjust it step-by-step to work with SAP HANA tools. We continue to improve our tools so that in the near future, there will be no need for these manual steps.

STEP 1: Add SAP HANA Tools Extensions to SAP Cloud Business Application Dev Space

The first step is to create an SAP Cloud Business Application dev space and add the following additional SAP extensions to it:

SAP Target Architecture. A Process Based Approach.

The switch to SAP S/4HANA or the introduction of completely new SAP components is very often considered as an exclusive IT task and is accordingly planned as an IT project. In the beginning, it is often forgotten that this is much more than a purely technical system introduction (upgrade). In addition to technical changes, potential changes in the previous way of working due to new processes must also be taken into account.

The consequence of this is, that successful project implementation is dependent on knowledge and active cooperation, equally on IT and the relevant specialist department.

Knowing the restart properties of SAP HANA parameters, change and monitor results from server level

Problem Statement & Use Case : Let’s divide the arose problems in two levels :

1. With the rise of hyperscaler managed services , if you are onboarded for a customer project only for some short term critical maintenance services like upgrades, migrations , often you are going to find several access issues for administrators specially on SAP HANA client level . And for say if you only have 2 weeks to accomplish your entire activity and raising a bug in DevOps to allow SAP HANA cockpit from your VDI and to have proper access to that and following up and eventually get that done in a completely new customer environment is quintessentially mess. It may end up with changing the firewall rules or a certain amount of unnecessary delay if you take my personal experience.

HANA – hdbcons first aid hacks

A tool which got more and more power since HANA 2.0 was released is hdbcons. It should only be used by experienced admins and should be tested in non-prod systems, because it can produce system crashes. There are several known issues documented in notes which describe scenarios you should avoid the usage of hdbcons in prod systems.

This blog won’t describe the full functional scope (the central hdbcons note 2222218). I will show some general use cases which are not well known, but should be kept in mind for scenarios I call ‘HANA first aid’. At the end of the blog you will also get an example script for such a troubleshooting situation.

SAP S/4HANA: Financial Planning with Commercial Project Management

Introduction

This blog gives an overview on the process to perform financial planning with commercial project management.  As a prerequisite, you need to know the concept of master project in SAP Commercial Project Management and project management in SAP S/4HANA Project Systems.

User Role – Project Manager / Project Planner

Commercial Project Management in S/4HANA plays an important role in the complete life cycle of a commercial project. Starting from the bid preparation (creating multiple financial plans for the bid based upon various scenarios, comparing them and finalizing the most optimistic version, transferring the finalized version to S/4HANA for execution) till project handover, major aspects for the project lifecycle (financial & commercial health of the projects, variation in the planned & actual cost etc.) can be analyzed and controlled from the master project created in SAP Commercial Project Management . Apart from that various issues, risks, opportunities related to the project can be managed with SAP Commercial Project Management. Change requests along with the financial impact due to the same can also be managed in SAP Commercial Project Management.

Version Management in SAP S/4HANA for central procurement – Central Purchase Contracts

Version management – Introduction

In the case of procurement transactions extending over a longer period of time (for example, in the procurement of capital goods), you may need to differentiate between various versions of the purchasing document. You may also need to refer to one particular version when corresponding with the supplier

Version Management enables you to generate and manage versions of purchasing documents. A version groups together the change documents generated  during subsequent processing of relevant documents. A version thus indicates the revision level of a document (version 0 = original document, versions 1 + = revisions) and provides the user with an overview of the various changes that may have been made in the course of time.
