This blog is for the detailed steps for Readiness Check (RC) for step t2 of conversion to S/4HANA 1809FPS0. Readiness Check is an optional step and is a high level analysis to get a Results Dashboard and also download to a Results Document with details of Active Business Functions, Add-On Compatibility, Custom Code Analysis, Recommended Fiori Apps, S/4HANA Sizing, Simplification Items, Business Process Analytics and Data Volume Management.

SAP S/4HANA

It is recommended to use Solution Manager, the diagram below is shown without SOLMAN to show the extra steps needed for running the check without Solution Manager.

SAP S/4HANA

STEP 1: De-implement any of the notes if they were implemented earlier. In case of ABAP class inconsistency, please clean up the class header in transaction SE24, specify the object and select Utilities -> Regenerate sections in the change mode.

If you face issues with above, please open OSS message. If you try to download latest version of note and apply, it may cause a bigger issue with a lot of time wasted later on.

STEP 2: Apply Note 2185390 – Custom Code Analyzer (includes manual steps)

This note downloads other dependent notes, and then some other dependent notes and this goes on. Number may vary depending on your patch level. The Note requires Manual steps as below:

SAP S/4HANA

As per Manual steps above, In SE80 create Package SYCM_MAIN

SAP S/4HANA

Create SubPackage SYCM_ANALYSIS

SAP S/4HANA

Confirm Manual step. Then the note application will prompt for another manual step depending on your SP level, its only applicable to the narrow range of SAP_BASIS SP08 to SP11 only.

SAP S/4HANA

In SE11, create table WBINDEX You will require the developer key and object access key.

SAP S/4HANA

Add field PROGNAME and confirm manual step.

SAP S/4HANA

In SA38, run SAPRSEUC in background. This is a long running job and runs single threaded by default. You can run it in parallel to save time as explained in the next step which is optional.

SAP S/4HANA

TIP: Please note it is not required to run the job SAPRSEUB, which updated Where-Used list for the whole system, the SAPRSEUC updates Where-Used list for Customization only. Job SAPRSEUB used to run several days like 11 days at one customer. The good thing is if it is cancelled it continues from the point it was cancelled with a overhead or 20-30 mins for every restart.

STEP 3: (OPTIONAL) Improve Performance of job SAPRSEUC. Apply notes below.

Note 2667023 – Runtime of job EU_INIT or SAPRSEUB/SAPRSEUC, performance Manual steps are in Note 2228460 – Runtime of job EU_INIT, SAPRSEUB, performance

SAP S/4HANA

You will have to register developer if needed, and register object to get Access key and fill in as below:

SAP S/4HANA

Add 2 fields as below:

SAP S/4HANA

In SE38, Variant , Change add text elements as below. there are 7 programs and 1 class with text elements to be updated.

SAP S/4HANA

After applying the note, job runs with one background process and uses number of dialog processes as defined in (1) table RSEUPACTRL as below. (2) Add column ALLSERVER, if it is blank, (3) Mark X for parallel processing and (4) define percentage of dialog processes to be used according to timezone. If this is sandbox that you want to finish the job as soon as possible you could jackup these percentages.

SAP S/4HANA

STEP 4: Apply Note 2310438 – SAP Readiness Check for SAP S/4HANA – Managed System

This prompts for applying Note 2185390 – Custom Code Analyzer and you already did it in earlier step, so confirm.

STEP 5: Apply Note 2504480 – Suite on HANA memory Sizing report – Advanced correction 9

Please note:

  1. Note requires minimum ST-PI 740/SP02 or 700,710/SP12 to apply the note.
  2. If you already have ST-PI 740/SP08 or 700,710/SP18 the note is already applied.
  3. If you don’t want to apply ST-PI, instead of applying this note, implement report ZNEWHDB_SIZE as described in Note 1872170 – ABAP on HANA sizing report Please note that if you take this option, there are 3 programs and function module to be created/updated to latest code.

ST-PI is independent and doesn’t need other components or stack.xml to apply, this would save lot of manual work.

In tcode SE38, check that program /SDF/HDB_SIZING is available and you can even run it for test. Please use below for troubleshooting if you run into issues. Please refer this after scheduling analysis with TMW_RC_DOWNLOAD_ANALYSIS_DATA.

SAP S/4HANA

STEP 6: Note 2399707 – Simplification Item Check. This can be applied quickly. There are no Manual corrections.

STEP 5: Note 2443236 – SAP Readiness Check for SAP S/4HANA Business Process Improvement Content. This can be applied quickly. There are no Manual corrections

STEP 7: In order to apply note 2612179 follow this sequence.

  1. in SNOTE apply Note 2611746 – DVM Create objects for APIs for triggering and monitoring ST14 analyses
  2. tCode SE38 run program NOTE_2611746
  3. In SNOTE apply Note Note 2612179 – DVM API to trigger and monitor DVM ST14 analyses for Readiness Check
  4. In SNOTE apply Note 2693666 – Enhance error handling when collecting DVM ST14 data for SAP S/4 HANA Readiness Check

STEP 8: Run background job in Development system to download repository metadata info.

In SE38 run background job SYCM_DOWNLOAD_REPOSITORY_INFO. Define the variant to restrict to the required namespace.

SAP S/4HANA

Then run the program in background using this variant.

SAP S/4HANA

STEP 9: Monitor the background jobs and download zip file.

SAP S/4HANA

In case you get below dump:

SAP S/4HANA

After the job is finished, in SE38 run SYCM_DOWNLOAD_REPOSITORY_INFO again and click on button to Download Zip file…

The solution is – Enter tCode SE38, Program LZEHPRC_CP_BB20UXX, click on Change (You will need developer access). Go to menu option Utilities, Settings.

SAP S/4HANA

select option above, click on OK, Save and Activate the program. Unfortunately you have to Rerun the job from the beginning.

STEP 10: Transport the 6 notes to Production

STEP 11: Run Background job in Production

in tCode SE38 – TMW_RC_DOWNLOAD_ANALYSIS_DATA create variant as below:

SAP S/4HANA

(1) Select items and (2) Schedule Analysis. This will trigger number of background jobs as shown in next step.

SAP S/4HANA

If you get this error, apply note 2443236 – SAP Readiness Check for SAP S/4HANA Business Process Improvement Content and also the needed ST-A/PI through SPAM.

SAP S/4HANA

STEP 12: Monitor the background jobs and download zip file. There are various jobs launched

Job TMW_RC_BPA_DATA_COLL is scheduled to collect Business Process Analytics data
Job TMW_RC_HANAS_DATA_COLL is scheduled to collect HANA Sizing data
Job TMW_RC_DVM_DATA_COLL is scheduled to collect Data Volume Management data
Job TMW_RC_SITEM_DATA_COLL is scheduled to collect Simplification Item relevance check data

SAP S/4HANA

After the job is finished, in SE38 run TMW_RC_DOWNLOAD_ANALYSIS_DATA again and click on button to Download Analysis Data as shown in previous step.

STEP 13: Generate Readiness Check Results Dashboard

In SAP Launchpad (S-USER is required) url (1) https://launchpad.support.sap.com/#readiness
(2) Import Analysis, (3) SAP S/4HANA, (4) Enter Analysis name, (5) select TMW_RC_DOWNLOAD_ANALYSIS_DATA.zip and (6) select SYCM_DOWNLOAD_REPOSITORY_INFO.zip (7) click on Upload

SAP S/4HANA

You can view the Results Dashboard and if you need to download report, click on Create Results Document and the report will be available in word format.

SAP S/4HANA

STEP 14: SOLUTION MANAGER CONFIG

  1. Apply Note 2290622 – SAP Readiness Check for SAP S/4HANA This is a note with elaborate steps.
  2. In tCode SA38 execute report AGSRC_START_ANALYSIS
  3. Enter the managed custom code client. Recommended to enter DEV system here
  4. Enter the analyzed system and client. Recommended to enter PRD system here.
  5. Enter eMail address of the user who should get the result of the analysis.
