Creation of Customized Infotype

Hi,

I have created an infotype, for which i have designed screens in SE80. But still When I execute the infotype in PA30 Transaction, I am getting an error saying that

Screen MP902400 2000 must not be an Include screen.

I am new to this HR module. Please give me a solution to solve this problem.

Thank You.
