  1. cool wiki + great help,  but hard to find this page

    why is this wiki not mentioned in the SUM guide ?

    1. Hello Christoph,

      thank you for your feedback.

      It is good to know, that our work is valuable for customers, especially for you.

      The pages can be found in google and we use references in KBAs also.

      The WIKI is referenced also in the Best practice guide which will be sent to customers who downloaded the SUM too, see offline version herel:

      I am not responsible for the  SUM guide, but I have forwarded your query to the authors.

      Best regards,






      1. maybe you can also submit the links to this wiki+blog to the SAP-SupportTeam of component BC-UPG-TLS-TLA  , because every time i opened a support-ticket to that team, while waiting (not only hours, but several days) for a really helpful solution to SUM-issues, now i have solved that issue, but did not get any response from that support-team yet, the support of that team is very very poor. (sorry to say that) - thanks.

  2. Hi Christoph,

    I have forwarded your feedback to the responsible team.

    You can also provide feedback directly after confirming the incident by filling out the survey.

    I have found a new incident from you and I have taken it. You will get an answer soon. 

    Best regards,

  7. we got an issue at S/4HANA-Conversion to 1909-FPS02 ( with SUM-2.0_SP08_PL02 ) in execution/downtime in phase MAIN_NEWBAS/RUN_B2_D_BVB_SETTL_MIGR 

    Checks after phase MAIN_NEWBAS/RUN_B2_D_BVB_SETTL_MIGR were negative!

    Last error code set:  Single errors (code <= 8) found in logfile 'BVBSETTL_MIG.ELG'

    ERROR:  Batchjob RWB2_D_BVB_SETTL_MIGR failed.   The following errors were detected in the log files:

    # /usr/sap/ERY/SUM/abap/log/RWB2_D_BVB_SETTL_MIGR.ERY:

    A4EESD_PROGRESS_LOG 012 "RUTDBCHK" at "WB2_D_BVB_SETTL" failed with returncode "8".

  8. Hi Christoph,

    I apologize for the delayed response.

    For the reported error I could find only an old note  2386258, I couldn't find any similar reported case.

    Next time please create an incident or chat if you need support for an error happening during a system update.

    Please attach the related logs also as they contain the exact error message.

    Best regards, Laszlo
