SAP S/4 HANA for Dummies: Convista in Asia

With the proliferation of digital transformation and all of its related technology consisting of RPA, cloud, AI etc. Software companies are swiftly adapting their current product services to fulfil the brand new wave of business demands. SAP, the behemoth in the ERP area is not any exemption.   SAP’s middle ERP product has usually been ECC however over the years the software program large has invested in developing a shrewd ERP system. This new gadget isn't an upgrade to its middle ECC however an entirely new commercial enterprise suite with a simplified core, an in-memory database designed by way of SAP, a grade-A function-based user enjoys known as Fiori, and extra flexibility to integrate and amplify clever solutions within the cloud with SAP S/4HANA cloud platform. It is referred to as S/four HANA. 

Benefits of SAP HANA database for S/4 HANA

  • In-memory database that improves speed and flexibility
  • Random access
  • Data stores in rows and now columns
  • Parallel processing is possible
  • Overall system improvement up to factor of 10-20
  • Data footprint reduced up to the factor of 40
  • Migrate to HANA DB in one step: Update and migrate in one step to reduce downtime and guarantee a seamless migration
  • OLTP and OLAP in the same SAP system: No latency, no aggregation, single source of truth

Question: What about SAP BW for OLAP

Answer: SAP BW is not dead but it is SAP core data warehousing tool. S/4 HANA embedded analytics is mainly for real-time analytics and is accessed from the Fiori launchpad

Methodology

SAP’s centre ECC product leveraged the ASAP technique for the assignment execution
ASAP Methodology 8X:
The levels encompass Project planning and preparation, blueprint, awareness (baseline config and tune-up config), very last practise, cross stay, submit go stay help
With SAP S/four HANA it's miles the activate method


ACTIVATE Methodology:


As against ASAP, the ACTIVATE technique isn't always just a technique but an entire FRAMEWORK. This encompasses
SAP excellent practices – ACTIVATE first-rate practice-based totally on scope, saves time from blue-printing interest
Guided config – Rapid Deployment Solution(RDS),  self-carrier configuration
Methodology- Consistent high-quality transport, prescriptive and accelerate product delivery
The ACTIVATE method is agile centric which helps clients – Start Fast, Build Smart, Run Simple. See information under.


Agile Projects


Agile ventures have small groups of 7+/- 2 with sprints to supply among 2-4 weeksThe team includes functional useful resource, technical useful resource, check useful resource, product proprietor, security aid, enterprise and solution supervisor, Mira and IBM Jest used to for ticketing gadget and exchange request to decorate design thinking SAP utilizes IRISE and SAP BUILD for interactive prototype

SAP S/4 HANA Migration and Deployment Options

Migration options

Greenfield: From non-SAP/SAP  to S/4HANA

Install SAP S/4HANA using the Software Provision Manager
Initial data load from source system using Migration  cockpit / Data-Services / Advanced Data Management by Syniti

System conversion (Brown Field):  No guided configuration
Use software update manager (SUM)

The source system does not have to be on a HANA DB
ECC must be Unicode- SAP ECC6 EHP 7

Landscape transformation

From ECC, CRM etc. into S4HANA. Consolidate to one instance
Deployment Options

On-Premise

Cloud: The following cloud options exist

SAP S/4HANA cloud: SAAS model, updates are quarterly, and no room for customization
SAP S/4HANA Cloud, Single-tenant edition: SAAS model, updates twice a year, and ability to customize

SAP S/4HANA Managed by SAP Enterprise Cloud: IAAS model, annual updates, extensive customization (not recommended) permitted.

The role of SAP Solution Manager (SOLMAN) 7.2 in S/4 HANA

Solution manager 7.2 facilitates change towards outcome-based delivery. Use solution manager 7.2 with best practice to deploy SAP S/4 HANA.  It acts as the ERP for SAP projects. It helps with fit to standard analysis, document scope requirement, project management etc.

Benefits of Solution Manager for SAP S/4 HANA

All methodology, accelerators and tools to customers in one area
Modern Fiori interface- track the build process, build cycles etc.
Tools for best practice (test scripts, process diagrams, config documents etc.)
SOLMAN helps to keep track of changes. It is a single source of truth for the project
Reporting:  In the project, SOLMAN has a solution readiness dashboard to track team member activities
S/4 HANA FIORI UX

To see a list of all the apps and the associated installation, please visit Fiori Apps Library.
Even if you do not know where to start, SAP can provide you apps recommendations by simply providing one month’s worth of transaction codes used through ST03N. See here for more
 information. SAP Fiori works with apps and it is built based on UI5 – JAVA, CSS. Use fiori front end server for each backend system- DEV- QAS- PROD. It helps with scaling and business logic

Details on ACTIVATE Methodology Phases:

Discover:

Determine licenses and use the trial versions in Cloud Appliance Library (CAL) – (30 days). Explore SAP Model Company for new implementation

Prepare:

This includes readiness steps, custom code management (what custom code do we need? How do we adapt to fit new data model?), project preparation and planning, organizational governance, team organization, sprint consideration.  For system sizing, consider the system size from the source. You can consider archiving. Use SAP DVM-Data volume management in solution manager

At this stage the following system planner and pre-checks tools are utilized:

The tool’s main focus is on the functional assessment that evaluates all available SAP S/4HANA simplification items and identifies the ones that are relevant for your system. This assessment provides a basis for the functional system redesign that is necessary upon conversion.

 The technical assessment includes system sizing and data volume management, the assertion of the software prerequisites for conversion, an inspection of SAP Business Warehouse (BW) extractors, and a first-pass estimate of the impact on the custom code. The software prerequisites cover OS and database versions of the ERP system, as well as the installed industry solutions, add-ons, and activated business functions.

The readiness tool can:

Can be executed on SOLMAN or not
Displays simplification items that pertain to your solution
Verify all system requirement

Pre-Checks

System sizing: HANA Sizing estimate- Use SAP Quick sizer in the marketplace to get the correct sizing. Corrects CPU, DISK etc

Custom Code Worklist: By readiness assessment or through ABAP Test Cockpit

Data Volume Management-DVM
Fiori -apps recommendation based on current transaction landscape. See S/4 HANA FIORI UX section above

Simplication item check – Notes to be implemented e.g.  Business Partner (BP)conversion

To start the simplification list, use transaction  /SDF/RC_START_CHECK. It checks system consistency during conversion/upgrade. Resolve error messages (mostly notes) and re-execute. Consumed by Software Update Manager (SUM). An example of pre-check simplification item will be the Business partner conversion

Maintenance planner

Formerly called maintenance optimizer. Maintenance Planner in solution manager checks the system with regards to business functions, industry function and adds-on. It is a prerequisite for SAP ECC to S/4 HANA conversion.

It checks add-ons, business functions, industry solutions
Generates XML stack

Stops upgrade, implementation or conversion if no path exists
Explore:

Fit-Gap analysis: Organize value identification workshop to determine the key business scenarios and define the roadmap to SAP S/4HANA

Process extension: Document and modify best practice graphics and see the configuration areas.
Testing: Identify test cases (all types of the test), supports a great testing environment and test suite
Config (New implementation): Guided config and implementation cockpit, solution designed template, requirement capture and gap, process re-engineering, best-practice workshop
Realize:

Configure in sprints based on requirements identified in EXPLORE phase (new implementation)
Utilize transaction SPDD, SPAU like in typical upgrade projects etc. for conversion migration objects to ensure data elements and dictionaries, reports, programs, FM and screens are in sync. SAP will identify changes and provide recommendations on how to proceed (conversion).
Data migration (for ECC there is pre-designed mapping for non-sap there is a canonical format). Migration cockpit (LTMC), data services, SAP SLT are tools that can be leveraged. LSMW is not recommended.

Data conversion: Data migration and conversion happens in downtime, system update can happen in the uptime

Custom Code Adaptation- Find issues using ABAP Test Cockpit
Software Update Manager (SUM) – Uses the XML stack generated by MP tool. This is the actual migration stage

Utilize a distributed system

Figure 1. The use of the distributed system for SAP S/4 HANA conversion
The following applies only to conversion projects:

Moved from SD to FSCM ( Financial supply chain Mgt)

The credit-control area is replaced with segments and global segments
External credit rating through external feed
Output Determination

No longer uses condition technique but BRF+ (Business Rules Framework). The functional consultant can use the predetermined rules.
Open code BRF+

Check note 2248229
Make sure BRF+ is in EXPERT mode. Go to tools and choose XML Export.
The functional consultant uses transaction OPD- To maintain condition records
Pricing

KONV replaced with PRCD _ELEMENTS
The limit to condition table has increased from 99 to 999
customer and document pricing procedure now has two-digit as opposed to  0-9 or a-z
PRC_MIG_POST_PROCESSING (SE38) – a program that should be run after ECC to HANA conversion.

Rebate-VBOX (index table changed)
Moved to a module called “settlement management”- good for retro-active rebate processing
ATP and TOR

No more cumulative requirement table – VBBS. S/4 now uses only VBBE
As a migratory step, in OVZ2 -Availability requirement check make sure you change from B-Cumulative to A.

Inventory Management

MKPF (Header) and (MSEG) item is condensed in MATDOC
Material ledger becomes mandatory in S/4HANA to help valuate in multiple currency and also sync costing between Balance sheet and P&L.

There is no doubt SAP has devoted significant resource to the development of the S/4HANA product line as every year new simplification items are introduced, migration tools are developed and project accelerators are introduced to assist customers to get on the transformation journey.
