Custom Infotype

Hello All

I have created a custom Infotype 9036, when I try to maintain it in PA30 Screen it shows following error:

"Object 00000000 does not exist

Message no. 5A040"

The error comes after I type 9036 in Infotype option of 'Direct Selection' and hit CREATE.

Any idea where I missed or mistyped information?

Thanks

Yash
