Saturday's final is not the first time Leinster and Glasgow Warriors have meet in the end-of-season shake-up.
Indeed, they have battled it out in the semi-finals in the last two years and here we take a closer look at their 2012 meeting where Leinster prevailed 19-15 at the RDS.
In what proved to be Glasgow Warriors' last season in at Firhill, Sean Lineen's side booked their place in the semi-finals with victories in their last two regular season matches, away to Treviso and at home to Connacht.
Leinster meanwhile, topped the regular season table, having finished second to Munster the year before, and were determined to avenge the 2011 Grand Final defeat to their provincial rivals.
Joe Schmidt's men began the brighter of the two sides but a cagey first half saw Leinster lead just 9-3 at the half-time interval - Jonathan Sexton kicking three penalties to Duncan Weir's one.
Another Sexton penalty and Dave Kearney's converted try on 66 minutes appeared to have Leinster sailing towards the final at 19-3 to the good but the Warriors were determined to go down fighting.
Dougie Hall touched down on 77 minutes but the Warriors could not convert and while Hogg went over in injury time - this time Weir converted - time ran out for the Scottish outfit.
"They never gave up, their defensive effort on the line was outstanding," said Lineen after the match. "You can't keep soaking up and soaking up the tackles and it told in the end," he said.
"We will take some consolation that the guys never gave up and came back to score a couple (of tries), but as I say it was too little, too late."
- 9 days to go - Glasgow Warriors have set a new club record to reach the Grand Final, racking up nine RaboDirect PRO12 wins on the spin
Leinster's performance was that of a side that would go on and lift the European Cup a week later and Schmidt was a happy man.
He said: "I was delighted with the effort and the endeavour. We certainly didn't hold back, I thought we defended really well for the 70 minutes until we got enough of a buffer and then we relaxed a little bit knowing that we had the game."
But Leinster were to fall short of the double they were targeting when Shane Williams dotted down two minutes from time and Dan Biggar held his nerve to convert to hand the Ospreys a thrilling 31-30 victory in the Grand Final.
