This was from yesterday's SAP User Group webinar covering SAP S/4HANA: New Deployment Tools for System Conversions.  It was full of new information (at least for me)

The Readiness Check is one of the oldest tools, and has been updated.

Simplification items


Efforts


Resources needed


Extend topic


Deep dive tools to help better assess/predict effort


Activities


Interface analysis - limited to BW extractors and Idocs




  • By end of year, may expect new features, new interfaces covered by this analysis


Business Partner is now included in this analysis


-enhancing this tile in readiness check, to give you more information


-customer/vendor records


Working on Finance

Run SUM, send to SAP


SAP has a database, not accessible to public


In that database collect statistics of upgrades/conversions


Collected data


Data by version, system type, productive or QA version


Intend to open data to public




  • An app in SAP Support launchpad - suggestions of how to shorten down time

  • How long phases take

  • How shorten some phases


It is a rough assessment, not a prediction


Will give you an estimate of how long it will be

Custom code


Now a commodity issue


Quick fixes - work in ABAP for Eclipse, automatically fix issues found in code inspector checks


60% automation with quick fixes


30% of code is unused - delete it upon conversion


Remaining with manual adaptation

When do a conversion, a chance to clean up system


If not done in conversion, it will stay in your system


When run sandbox conversion, update UPL or code monitor


Import stats in custom code Fiori App - creates transport

Available in ABAP in SCP

Only available in cloud


Response to question of how to go to back to standard program


SAP developing an approach to this


Measure how difficult it is to read / manage custom code


How often custom code changes


Bubble represent development packages - how difficult to maintain and change


Upper right corner is where money is spent fixing most difficult development packages


Tried with a few customers - picture is the same as above


Up to 1/3 to 1/2 able to find in S/4 to replace customer code

This one is little known


Fix custom code in sandbox, chances to get them to development - this is where retrofit comes into play


Custom code adaptations to feed back in


Helps to stay in sync

Standard conversion - less than 5TB


High end option for large systems - NZDT technology - minimization service - need SAP Services - also available for 1909


Middle option - starts converting to new data structures in up time, records changes, a stable technology, starting 2 years ago; preparing certification for partners so not limited to SAP Services


Bottom part shows a live example - First conversion took 111 hours; then with optimized downtime down to 24 hours

Finance conversion - several table changes, many tables become obsolete as move to universal journal


Tables have inconsistencies in redundancies in old data model


Root causes are different


Run this 3 to 6 months prior to conversion



Figure 11 Source SAP


Business partners are checked for inconsistencies

NEW IMPLEMENTATIONS

Can't use LSMW; can still run but not supported or recommended


Use migration cockpit


Data construction - data that you don't have today



Figure 13 Source SAP


S/4 Migration Cockpit



Figure 14


Migrate open items and master data - RFC connection


120+ objects available



Figure 15


What Idoc needed


Uses machine learning and crowd sourcing


Pricing for run time and design time
