The Latics, who meet the Lions at Wembley on Saturday, currently sit 18th on the table with seven matches remaining and Scharner has assured the clubs supporters that the FA Cup festivities are not distracting them from the major job at hand.
"Of course (survival is the priority) because it's the future for Wigan and it brings the money to run the business," said the Austria international who is on loan from German club Hamburg.
"But I don't see a problem to be in the semis and fight against relegation because it's a little island outside of the relegation fight to enjoy another football match.
"I think every single player should enjoy their time there because it's not very often you're playing at Wembley with Wigan in an FA Cup semi-final.
"It's a different pressure. We have the relegation pressure, which is very hard to handle to be honest because you have to get the points to stay up and secure the future. This is different because it's one match.
"Wigan has a lot of experience now in the relegation fight. It does bring also pressure on you because everybody's expecting Wigan to survive again. What we need to focus on in the last seven games is get nine points, that's it."
