2. Frequently Asked Questions

#1 Can I generate a results document as MS Word from SAP Readiness Check 2.0?

SAP Readiness Check 1.0 supports the word document generation so that you can download your results to work offline and share your results with consultants from SAP and partners.
Based on your feedback, we will support this option for SAP Readiness Check 2.0 in future: You will be able to download a MS Word results document together with all SAP Readiness Check list results (e.g. Simplification Items, Custom Code, BW extractors, Fiori apps..) as MS Excel in one zip-file.
It is planned to release this feature with SAP S/4HANA 1909 (middle of Sept).

#2 IDoc – why are the blocklisted IDocs always 0?

As of today, for all analyses, the backlisted IDoc number is always 0. The reasons are:

1. customer specific caller programs (“wrappers”) will not be part of the standard SAP S/4HANA backlist and will not be evaluated

2. Only the caller program itself will be evaluated but not the coding used inside

We are currently checking internally how to improve this data.

Sometimes the total number of IDoc is very big.
Reason: all customized IDocs w/o runtime data and all customized IDocs with runtime data are countered. This is done for both directions, Outbound and Inbound

Refer to this blog for further information and follow-up recommendations:
SAP Readiness Check 2.0 – Details about the topic of Integration

#3 When can we run SAP Readiness Check for the next SAP S/4HANA release?

Usually around August / September many customers ask when SAP Readiness Check will support the next SAP S/4HANA release and what  the preparation steps are. In general:

SAP Readiness Check supports the next SAP S/4HANA release automatically from the day the new SAP S/4HANA release is released.

The following tiles are impacted when a new SAP S/4HANA version is released: Add-ons, active business functions, Simplification Items, Activities related to Simplification Items, recommended Fiori apps.

For preparation: There is no need to update the implemented SAP Notes:
If you have already implemented the relevant SAP Notes (see SAP Note 2758146) and set up your SAP ECC system correctly, you can just run a new SAP Readiness Check analysis choosing the new target release from the dropdown.
That being said it is always recommended to have the latest version of SAP Note 2758146 implemented.

Note: Some customers may not be able to see the latest version due to a missing connection between their SAP ECC system and SAP support system. In such case, download the latest content from https://launchpad.support.sap.com/#/sic/overview and use report /SDF/RC_START_CHECK from SAP Note 2399707 to “Upload Simplification Item Catalog from file”

#4 Who can see my analysis?

Once an analysis is created, it is visible to all s-users which belong to the same customer number.
When uploading your Zip file, you can tick the second box to acknowledge that all SAP employees may access and use the SAP Readiness Check Results for SAP business purposes like support, services, and marketing.
If you would like to share the analysis with selected SAP employees or partners, you can

  • create an s-user for them
  • use the “Settings” button on the top right to grant access maintaining their email address

 

#5 What authorization is required to perform SAP Readiness Check?

The user must have Activity 16 (execution) of authorization object S_DEVELOP and authorization object SM_BPM_DET with Characteristic of ‘OBJECT_MS’ (collected KPIs) to perform SAP Readiness Check.

#6 Which system and client shall SAP Readiness Check be executed on?

SAP Readiness Check needs to be executed only once per SAP ECC system.

SAP Readiness Check should be run in the production system and must be run in the productive client. This ensures that all checks are executed properly. In case you have more than one productive client the result of the Business Process Reality Check will currently only include the analysis of the client where Readiness Check was executed. All other SAP Readiness Check analyses are client-independent and you will always get complete results of the ECC system considering data of all productive clients.

#7 Add-On and/or Business Function tiles are empty

Please make sure you have maintained your system data in SAP Maintenance Planner either:

  • as per SAP Note 2287046 – How to Generate the System Info XML and upload to Maintenance Planner or
  • via SAP Solution Manager

If data is still now showing up, please open a support incident on component BC-UPG-MP.

#8 What is the expected performance impact if I run SAP Readiness Check on my PROD system?

On an average system with 2 TB database, the performance impact should be at most 10%. If you have high system load in general (which you should not have according to Best Practice), you can run the job over the weekend. If you have normal system load with normal peaks, you can run the job throughout the day which takes usually a few hours for systems up until 2 TB. Most performance impacting checks are the DVM and sizing check. You could go ahead and schedule only these checks for the weekend alternatively.

Note: you should investigate these performance issues in general because you will need to run the Simplification Item Checks on your Production System at some stage during your production system conversion week. If SAP Readiness Check is taking a long time, Simplification Item Checks will likely be even longer.

      Hi,

      We’re pursuing the below approach for migrating our multiple ERP production systems to S/4 HANA 1809. Having said that, does readiness check 2.0 and simplification item checks are required to run or applicable to this scenario as well?

       

      “Selective data transition using Landscape transformation”

      Hi Dheeraj, sorry for my late answer! It depends on what sort of SDT project you are doing.

      If you create a brand new system without any data but keeping configuration and custom code, then the sizing tile and data volume management part will not be relevant for you, but all other tiles are.

      In any case I would run Readiness Check as either way some tiles are relevant.

      Kind Regards,

      Ariane

      Hi Ariane Hoffmann

      On the similar lines, if we want to create a shell copy and then convert the shell copy to S/4 then can you please mention as whether RC is even needed at all? And if at all is needed then which all sections would be relevant.

      Asking because the shell copy is generally an empty system (no master or transactional data) but would have only customizing and custom code repository. So when there is no data in the system then all data relevant tiles in the RC in my opinion would not be needed.

      Many Thanks in advance

      Regards,

      Pankaj Agarwal

      Hello Ariane,

      We executed the RC report unfortunately one time in 000 client, then we noticed that it was not right. And we had executed one more time in the productive client. Both collected results had almost same data size (I mean zip files downloaded from rc report).

      And then I thought that maybe we should delete buffered data in the report after that it could be better. So we did it and executed last time. Data size were this time circa 150 KB pretty low by comparison with previous.

      So, my question; is that a fatal mistake for the RC analyse? could be that results reliable?

      Kind Regards,

      Fetih

      Hi Fetih,

      That to execute the collect data report in productive client is right.

      For the data size question,  I would like suggest that you can extra the zip file and compare the each XML file size.

      If something is wrong here, you can create customer message for component "SV-SCS-S4R".

      Hello Ariane,

      Can you please confirm if ReadinessCheck 2.0 can be used for clients already on S/4HANA but upgrading to 1909 by example to calculate the delta on code and innovative business solution?

      First of all- almost all OSS notes are available and installed on S4HANA, and on some notes I see mentioning of deltas between 1709 and 1909;

      If you can confirm or infirm..

       

      Thanks,

      Hi Sorin, I am very sorry for my late reply, I did not receive any notifications for questions here.

      No, Readiness Check does not support S/4HANA as source release. We are working on a Readiness Check for upgrades though.

      If you are currently planning an upgrade, please use:

      Hi Ariane,

      Need Urgent Help

      Currently we are planning to upgrade system from SAP S/4HANA 1610 to SAP S/4HANA 1909 and wanted to check if there is any tool available to perform custom code analysis and to get the details on how we can prepare our system for 1909 Upgrade.

      or can you please confirm if Readiness Check 2.0 still does not support upgrade scenarios to analyse the system data?

      Hello Everyone,

      FYI.

      After some discussion with SAP, I understood that readiness check 2.0 is no longer supported from solution manager. Running the analysis from solution manager has been discontinued.

      Thanks.

      Hi Deepika,

      really sorry for my late reply and you are correct - the option to run Readiness Check via Solution Manager has been retired and will not be available again in future.

      Hello Ariane,

      How can we download/export our comments from the RC 2.0?

      We have previously generated a first RC 2.0. In this first analysis, we have manually added comments
      - for simplification items – the manual status – rationale why each is in scope/out of scope
      - for add-on functions – the manual status – rationale why each is compatible/incompatible

      It is possible to generate a ‘results document’ in a zip-file containing multiple spreadsheets and a word document. However, we unfortunately cannot see/find the before-mentioned comments in any of these.

      The consequence is that the "comment feature" is not really useful. When we create a second RC 2.0 analysis, we need to re-enter comments.

      Suggest a future improvement ...;)

      Best regards Thyge Friis

      Hi Ariane,

      Need your suggestion on below.

      We ran S4 Readiness check 2.0 in Test system. TAANA ANALYSIS  job took almost 73 hrs to complete.

      This  Job spent almost 55+ hrs of  time at one particular table which is having 3612370000 entries (1.5 tb of size). Total db size is 20TB. 

      Would it be possible to use parallel process to finish this quickly in production system ? or any other alternate options we have to speed up this ? just fyi, in test and prod we have same memory configurations.

      Would it be okie If we consider running this readiness check only in Test  by bringing latest st03n data from production to test?

       

      Thanks,

      Sandeep

      Hi Sandeep,

      Thank you for your question!

      The TAANA analysis check is known to run long in larger systems. The collection process is designed with the intent to minimize workload consumption on the source system. If you attempt to expedite the data collection process, more capacity will be consumed. In the end, you would need to balance your interest in reducing the duration of the runtime and the overall consumption of system capacity. There are multiple available options for you to consider, including:

      1. Validate the completion of all DVM preparation steps as outlined in SAP Note 1159758
      2. Disable the DVM option in the selection screen of the data collection program, but realize that the guidance would not be available for this system
      3. Run the DVM data collection separate from the rest of the SAP Readiness Check data collectors by scheduling multiple executions with different selections
      4. If you have further concerns, you can create an SAP Incident under the component SV-SMG-DVM to further evaluate the runtime performance

      Kind Regards,

      Ariane

      Hello Ariane,

      Thanks for the great blog and information.

      You mentioned that for multiple productive clients, some results are not delivered for all clients. I also checked the note where it mentions -

      "Business process discovery check, business partner check, and the data volume management check will only include the analysis of the client where SAP Readiness Check was executed"

      Are there anything we should keep in mind while running Readiness Check for mutliple production clients - if we want complete results?

      And another question:

      If we split the extraction job to have the DVM run later (for performance reasons), can we upload the extraction results sequentially while ensuring the 2 extractions do not overwrite each other?

      Or is there a way to bundle the individual job runs into a single zip?

      Hi John,

      Thank you for your question. Integration, Customer Vendor Integration Analysis and Financial Data Quality tiles are also client dependent.

      And yes you can run and upload your DVM separately.

      Kind regards

      Hi SAP Team,

       

      This is a helpful blog.

      I have a basic doubts on the Readiness checks for S/4 HANA Conversion 2020.

      1. What is the difference between /SDF/RC_START_CHECK and RC_COLLECT_ANALYSIS_DATA reports?
      2. What is the best option to run the /SDF/RC_START_CHECK in parallelism?

      Hi Prabhu,

      Report /SDF/RC_START_CHECK is for detailed simplification list and RC_COLLECT_ANALYSIS_DATA is for Readiness Check.

      I am not aware of parallelism in /SDF/RC_START_CHECK but if the report is taking longtime please try the methods suggested in opensap course Week1 Topic 3 towards the end -  https://open.sap.com/courses/s4h14-1/items/1xmyNDSayheuZCaKbWfW1q

      Hi,

       

      I ran Readiness check 2.0 two time. it got failed on TANA ANALYSIS with DB memory limit. after increasing the DB memory limit, when i ran the job again then it did not triggered TANA ANALYSIS.

       

      what could be the reason and how to re-run it again?

      Hi Ariane,

       

      Great blog entry! It's very informative 🙂

      I have 1 question though that I hope you can shine some light on.

      • We already executed RC in year 2018. The one we did is with Solman and I read in 1 of the comments that this approach is already discontinued. Does this mean that we have to re-do all the setup and note installations that we previously did? or RC v2.0 is totally a new approach?

      Thank you in advance. 🙂

      Hi,

      We are upgrading ECC 6.0 EHP8 to S/4 HANA 2020. We have separate SAP Boxes for below Add-on's on ECC.

      SAP APO 7.0 ADD-ON EHP4 ON ERP 6.0 EHP8
      SAP RETAIL ADD-ON ERP 6.0 EhP8 SPS15

      1. Can we perform Readiness Check on above Add-On systems?
      2. What will be recommended approach to perform Custom code analysis on Add-On systems?

      Thank you.
