SUM_Error in phase PREP_GENCHECKS/JOB_RSUPGRCHECK_PRE

Issue:

We have faced issues during the PREP_GENCHECKS/JOB_RSUPGRCHECK_PRE phase. The SUM tool need a manual correction to implement the SAP note.

SUM

Even though the mentioned SAP note is in “can not be implemented” status, we have followed the SAP note to implemented via SA38 report “SCWN_TRANSPORT_NOTES”.

But nothing worked out. Even we have faced the same issue again.

Solution:

SAP note number : 2255834

  2255834 – SUM prompts for Notes with status “Cannot be implemented” during the phase PREP_GENCHECKS/CHECK4NOTES_PACKAGES

Issues fixed. We have moved to next phase successfully.
