Also apply the notes mentioned in OSS note 3061414 – Enabling extended integration impact analysis for SAP Readiness Check, if you want to include ALE scenario’s in your analysis.
As you can see from the list of OSS notes there are improvements in the area of idocs, data volume management and business process analysis.
For this reason SAP recommends to run the S4HANA readiness tool on productive system.
It is possible to run on a recent copy, provided you copy the ST03N data from production to the recent copy. This process is described in OSS note 2568736 – SAP Readiness Check for SAP S/4HANA – copy ST03N data.
Troubleshooting guide is OSS note 2968380 – SAP Readiness Check Report 2.0 – troubleshooting guide.
Run S4HANA readiness check 2.0
There are 2 data analysis programs to run: SYCM_DOWNLOAD_REPOSITORY_INFO and RC_COLLECT_ANALYSIS_DATA.
First you run SYCM_DOWNLOAD_REPOSITORY_INFO on development system to fetch information about your Z coding:
The tool will launch batch job. After job is done download the zipfile to your local PC.
If you are asked to regenerate the ABAP indexes run program SAPRSEUC in the background and be very patient. See blog on ABAP where used index for more background information. See also OSS note 2655768 - Custom Code Analyzer - The where-used list index for customer objects is not up to date.
Second program you need to run on production. So you first need to transport all the notes to production. The notes are large and can take up to 20 minutes import time. So take a quiet time at the productive system to import them.
Start program RC_COLLECT_ANALYSIS_DATA in your productive system:
Select your target version and press execute. This will launch multiple batch jobs. Wait for all the jobs to finish and start program again to download the ZIP file to your PC.
As explained in OSS note 3071549 – Buttons in the report RC_COLLECT_ANALYSIS_DATA the report RC_COLLECT_ANALYSIS_DATA now has a link to the CVI integration (customer vendor).

Differences between S4HANA readiness check 1.0 and 2.0
- More aspects are covered in 2.0 (like idocs, data volume, business processes, etc)
- 2.0 is fully online, it is easier to give access to the site (entering e-mail is sufficient, no need for S user to access), you can still make word summary or xls download of the results
- The analysis programs are faster
