Passing Parameter to PA30

Hi guys,

As we have many links from Portal that requires access to PA30, but accessing different Infotype, I was wondering that when Portal calls PA30, is it possible for Portal to pass the infotype(e.g. 2001) as parameter to access the SAP Transaction so that it would reduce additional effort required by the user to enter the infotype in the input field?

Regards,
