3 days ago I posted an answer/reply to the question: https://answers.sap.com/questions/34953/ase-date-range-partition-1.html .
At the end of the answer I added a hyperlink to the DSAM manual @ help.sap.com: DSAM manual (like I just did for this post); and yes, at the time I submitted my answer I verified the link was working and in fact took me to the desired PDF @ help.sap.com
NOTE: A review of the post's revisions confirm the hyperlink *was* originally in the answer/reply, but appears to have disappeared after a minor edit of the answer/reply ... wtf ?
This morning I was reviewing the thread and noticed that the hyperlink to help.sap.com had disappeared (been removed?) leaving the link's text as normal text ('DSAM manual').
I've gone ahead and re-added the hyperlink to my answer/reply.
I'll post back with more examples of disappearing hyperlinks if/when I find them.
NOTE: It appears the new system automagically converts URLs to hyperlinks (eg, help <dot> sap <dot> com); the only hyperlink I added to this post was for the 'DSAM manual'.
