The meaning of RABAX

I was a little amused at language used in note 1680814. It talks about "In transaction ST22, search for rabaxes that occurred at the same time. In the rabaxes, you now have to try..."

Most of us know that RABAX is web-speak for dump, because that's how a dump appears in the browser. But what does the term actually mean, is it an abbreviation or acronym of something? Is this a start of a global renaming of our beloved "dump"?

A bit of googling tells me it's an SAP term, not used anywhere else.

So can anyone enlighten me?
