We've already learned that SAP Support does not really see the 'Steps to recreate' section in their ticket system, so I don't bother filling that in anymore and just put everything in the description. Now there is either another section missing from what the SAP Support sees or there is an outbreak of some exotic disease that affects one's reading abilities among the support employees. Otherwise I'm not sure what could be the reason for a "proposed solution" that includes the note we've clearly already applied:
By the way, the 'additional' note is in German but, from what I could tell in Google Translate, the symptom does not match what was described in our ticket. Well, that's just icing on the cake.
