Supply them with a link to this conversation. Professional scrutiny can work wonders
Yes AGS, I am talking to you. 
Now listen up. I work in support - I know what it's like and I understand the temptation to kick back. But, frankly, you're not qualified. You're dealing with people who know more than you do. We may not work for SAP, but we've been doing this since you were in nappies (American: diapers ).When you encounter someone who knows more than you, listen to what they say. If it's beyond your pay grade, kick it upstairs.
When you're in a hole, stop digging..
