Readi­ness Check 2.0: under­stand S/4HANA transfer

How are we prepar­ing for SAP S/4HANA imple­men­ta­tion? Does my cus­tom code work in SAP S/4HANA? How about those busi­ness func­tions or add-ons we use? And integrations?
How can we best uti­lize SAP Fiori? What Fiori appli­ca­tions do we need and how we imple­ment them?
How do busi­ness process KPIs look like? How can we improve them?
How much serv­er capac­i­ty do we need in order to run SAP S/4HANA?

These are some of the ques­tions that come in mind when think­ing about start­ing SAP S/4HANA project. The best tool for find­ing answers is SAP Readi­ness Check 2.0.

SAP Readi­ness Check has been in use since May 2017. Two years lat­er in May 2019 the new func­tion­al­i­ties con­tain­ing Readi­ness Check 2.0 were intro­duced. The results from Readi­ness Check 1.0 can still be uti­lized till the end of 2019, but SAP rec­om­mends mak­ing a new analy­sis with Readi­ness Check 2.0.

Com­pared to the first ver­sion, Readi­ness Check 2.0 includes many new and improved analy­sis tools but also dash­board look and usabil­i­ty are improved along the design based on SAP Fiori 3.0. Readi­ness Check 2.0 can now be used only as an online appli­ca­tion and it can’t be down­loaded yet in Word-for­mat report as in Readi­ness Check 1.0. This func­tion­al­i­ty has been replaced with new autho­riza­tion con­cept which brings flex­i­bil­i­ty for result uti­liza­tion. The autho­riza­tions of each analy­sis’ results can be man­aged in SAP Readi­ness Check appli­ca­tion and S‑user doesn’t need to be cre­at­ed for every­one who needs access to the results. This way autho­riza­tions lev­els (read-only vs. edit­ing per­mis­sions) can be eas­i­ly managed.

SAP Readi­ness Check 2.0 prepa­ra­tion in ERP sys­tem is exe­cut­ed in a same way as in pre­vi­ous ver­sion. The analy­sis runs’ end results in devel­op­ment and pro­duc­tion sys­tems are zip files that are uploaded to SAP Readi­ness Check 2.0 appli­ca­tion. After this, the analy­sis itself takes less than half an hour to com­plete. If need­ed, the analy­sis can also be updat­ed lat­er by upload­ing a new zip file to the appli­ca­tion. There­fore, for exam­ple, Sim­pli­fi­ca­tion Item analy­sis part can be updat­ed while oth­er parts’ con­tents remain the same. The dif­fer­ence between Readi­ness Check 1.0 and 2.0 prepa­ra­tions is that the new­er ver­sion can’t be pre­pared via Solu­tion Manager.

Sim­pli­fi­ca­tion Item Check in new Readi­ness Check lists all the nec­es­sary actions with­in each item. Those actions can also be sep­a­rat­ed to dif­fer­ent cat­e­gories based on if they are manda­to­ry, con­di­tion­al or option­al. Man­u­al sta­tus and com­ment field of each item help divid­ing work and track­ing progress. The items are already divid­ed in cat­e­gories accord­ing their rel­e­van­cy from the cur­rent ERP system’s point of view. There­fore, the most impor­tant and urgent activ­i­ties can be focused right from the begin­ning of a project.

Same than in Sim­pli­fi­ca­tion Item Check, Add-On and Busi­ness Func­tion Check func­tion­al­i­ties are also being improved in Readi­ness Check 2.0. Renewed cat­e­go­riza­tion, com­ment field and pos­si­bil­i­ty to man­u­al­ly add third-par­ty Add-On com­pat­i­bil­i­ty ease under­stand­ing data and track the sit­u­a­tion. A new part in Readi­ness Check 2.0 analy­sis, besides inte­gra­tion part Busi­ness Ware­house Extrac­tors, is iDoc inter­faces. The analy­sis lists iDoc inter­faces that might cause prob­lems when trans­fer­ring to SAP S/4HANA environment.

SAP Readi­ness Check analy­sis is a good basis for SAP Fiori imple­men­ta­tion. Readi­ness Check offers rec­om­men­da­tions for busi­ness roles and Fiori appli­ca­tions based on the analy­sis of cur­rent SAP ERP system’s trans­ac­tion use. If there is no pre­vi­ous Fiori imple­men­ta­tion, the most rec­om­mend­ed start approach is to exam­ine rec­om­mend­ed Light­house SAP Fiori appli­ca­tions list, which con­tains SAP key appli­ca­tions. Fiori appli­ca­tions are divid­ed accord­ing to busi­ness roles what helps to under­stand the Fiori con­cept. Those roles rec­om­mend­ed by Readi­ness Check can be man­u­al­ly set In Scope or Out of Scope sta­tus and appli­ca­tions can be tagged as favourite what helps keep in track the selec­tion of suit­able Fiori applications.

Oth­er notable func­tion­al­i­ties are for exam­ple Busi­ness Process Dis­cov­ery which iden­ti­fies busi­ness process opti­miza­tion poten­tial, and SAP S/4HANA Siz­ing sim­u­la­tion where data­base size change can be eval­u­at­ed accord­ing to the growth from new func­tion­al­i­ties and reduc­tion from Data Vol­ume Man­age­ment actions.

SAP Readi­ness Check is an impor­tant part of ISLET S/4HANA assess­ment. It is used for both tech­ni­cal and appli­ca­tion side reviews. Fur­ther­more, in the assess­ment busi­ness val­ues are explored when trans­fer­ring to S/4HANA and roadmap is made for the upcom­ing years. We car­ry out assess­ments accord­ing to customer’s needs with dif­fer­ent empha­sis. We are hap­py to tell you more.
