Law and Syme were sitting fifth and ninth respectively on the reserve list first thing this morning, but have now been added to the star-studded field.
As has Warren, who, despite being below Scott Jamieson on the standby list, has secured the final invitation ahead of his compatriot.
That could be because Florida-based Jamieson has decided to commit to the Barbasol Championship, which, like the Scottish Open, is being co-sanctioned between the DP World Tour and PGA Tour.
The trio join Ewen Ferguson, Stephen Gallacher, Grant Forrest, Bob MacIntyre, Russell Knox and Richie Ramsay in flying the Saltire in the $8 million Rolex Series event at The Renaissance Club.
Law’s addition to the field came less than 24 hours after he’d secured a spot in the 150th Open at St Andrews next week through finishing joint-fourth in the Phoenix Irish Open at Mount Juliet.
The Aberdonian will be making his fourth successive Scottish Open appearance, having opened with two 67s last year before finishing in a tie for 35th.
Syme will also be playing in the event for a fourth time, having made the cut in all three of his appearances so far.
Warren will be teeing uip in his 18th Scottish Open, having recorded three top-four finishes, the most recent being just tw years ago.
With 14 of the world’s top-15 players in this week’s field, it is the strongest-ever regular event on the DP World Tour, which was formerly the European Tour.
The last time a non-major, WGC, The Players or FedEx Cup Play-Off event had 14 of the top 15 was in the 2007 Wachovia Championship.
