I know that I must have written this blog long ago when the project finished. Although I started writing I could not finish it somehow .

I decided to finish it when we had chance to represent our project as success story at Teched Barcelona.

In my blog Going to Teched 2016 Barcelona I already mentioned about our first S/4HANA migration project and my boss’s (Hüseyin Bilgen) blog SAP S/4HANA Journey started in Turkey – TechEd Barcelona 2016 and about the Teched session.

As the technical consultant of the project I want to share what I did in the project, what the difficulties were and what I got from the project as a technical guy.

First of all, What I did during the project;

When we migrated to SAP Simple Finance, the version was “SAP Simple Finance, on-premise edition 1503 support package stack 1508“.  The name was “SAP Simple Finance” at that time and now it is called as “SAP S/4HANA Finance”. HANA DB version was revision 102 of Stack 10. The documents were according to these versions.

Since it was a new topic I searched for the guides firstly. I knew that I had to read guides, notes and any referred documents carefully.

There was an install and upgrade checklist attached to the note “2157996 – SAP S/4HANA Finance: Checklist for Technical Installation / Upgrade“. You can find the checklist of current version attached to this note.

There were notes to apply to the system before, during and after upgrade.

I went through the info given SAP Simple Finance Administrator’s Guide at http://help.sap.com/sfin200 (for release 1503) in mentioned note. The name of the guide was SFIN_ADMIN_GUIDE_202.pdf.

The upgrade sequence was described as below in the admin quide.

There are also tables that describes the sequence of the upgrade. I followed those tables, too.

After the preperatory steps we copied the production system to a test system (System Copy). This step is crucial for upgrades, because of having a close system to the production system and simulation of the real upgrade process.

I run Maintenance Planner (it was maintenance optimizer before as you know) to get stack xml and download required support packages.

Latest Software Update Manager 1.0 SP14 (SUM) was the tool that I used to upgrade our system from source to target system version as seen below.

There were Post Installation Steps mentioned in the admin guide and there were also notes  which must be applied directly after the upgrade to “SAP Simple Finance on-premise edition 1503 support package stack 1508” mentioned in RIN “2117481 – Release Information Note: SAP Simple Finance, on-premise edition 1503“.

One of the post installation steps was “Technical Installation of SAP HANA Live 2.0, Virtual Data Model for SAP Simple Finance, On-Premise Edition”. I had some problems when I was installing Live components to HANA DB and I solved the problem with the help of SAP guys. ALM was the tool to install HANA Live components.

With HANA Live Browser (http://<HANAHostName>:<port>/sap/hba/explorer/) application you can quickly and easily search, browse, tag and consume HANA analytical content views using an internet web browser. You can open definiton or content of views,  Open View in SAP Lumira, Open View in Analysis Office.

I can give some usefull links abbout HANA Live.

I must mention about the Setup of SAP Fiori System Landscape for SAP Business Suite as one of the key topicsof the project. We installed a gateway system landscape (dev-prod) for the implementation. Here are some useful links for the topic.

SAP Fiori for SAP Simple Finance, On-Premise Edition

SAP Fiori Implementation Information

The “SAP Fiori apps reference library” enables you to explore, plan and implement SAP Fiori, the new user experience for SAP software.

Here is the architecture of the System Landscape for SAP Fiori Apps.

As the Second, what were the difficulties?

* Landscape was big enough. HANA DB, HANA Live, Business Suite, SFIN, Fiori are all included in the project.

* The topic was so new as it was the first implementation of SFIN in our country.

  We opened some OSS messages to get help. SCN discussions were not enough.

* Keeping track of all implementations in order was difficult. (Thanks to Onenote helping me about this)

As the Third, what I got from the project as a technical consultant?

* I practiced many topics about HANA

* I will have a chance to goto Teched with this project

* I have been the very first technical guy that implemented SAP Simple Finance in Turkey

* I had an experience of implementing HANA Live and SAP Fiori

* Good feeling of finishing a successful project

And as the final words, the project was successfully implemented as the first implementation of SAP Simple Finance in Turkey.

Customer was happy about the project. Users were happy about the performance of the new UX and new transactions. They are using HANA Live Browser, too.

I hope I will be included more S/4HANA projects in the future.

Thank you for your interests.
