Lisicki, who is aiming to win a fourth WTA tour title, defeated Magdalena Rybarikova in the semifinals 7-5 7-5, while Erakovic defeated Switzerland's Stefanie Voegele 6-2 6-4.
In the women's draw, Serena Williams meets Stefanie Voegele in the first round but it is her potential last eight face-off against Henin that has caught the eye.
