Generating a Custom Transaction in a BSP page

Hi everybody,

In our CRM we have developed a custom transaction.

Now, we would like to view the transaction through a BSP page and after we would like to link the BSP page into our Enterprise Portal.

Are there any program in CRM on line to build a BSP page starting from a Custom Transaction??

Can you suggest me any tips or any documentation to do this???

Thank's a lot.
