Wigan's achievement in reaching this month's Wembley showpiece for the first time in their history is being overshadowed by yet another battle against the drop in the Barclays Premier League.
Latics are five points from safety with just four games to play.
They do have a game in hand on their relegation rivals but their fixtures must be fitted around the final on May 11.
That means nervy midweek games either side of their trip to Wembley but Martinez denies it is a complication.
The Spaniard said: "I heard it could be a distraction but, believe me, it is not a distraction at all.
"If anything, it is a sense of pride. To be in this position is a huge achievement. To be facing the FA Cup final is an historic moment and we are all extremely proud of it.
"That gives you a positive feeling - around the town, around the fans and around the dressing room.
"We are taking every game in the league with the importance it has. We all understand that is the priority. But having an FA Cup final is a fantastic reward to fight for in the league.
"From the players' point of view, that is what you are fighting for at the end of a game in the league. That is going to help us perform as well as we can in the next four games in the league."
