How to get around nested portals


     I'm trying to figure out a way to do this:

     Our master table (Entities) contains records relating to different individuals, companies & properties.  Basically, anything with and address and phone number.  In order to keep track of which entities own which companies I created a second table "Ownership".  This table is a one to many relationship to the entities table based on on ID field that records which entities own other entities and how much they own (a percentage).

     With a simple portal I can show this ownership.  My problem arrises when one company owns another company.  

     The basis for the database is to provide what-if and tax planning analysis therefore, we need to be able to show, not only, the companies that own companies but also, all individuals that own those companies.  And, be able to calculate a total ownership for each individual.


     Company 1 is owned by

          John Doe 33%

          Jane Doe 33%

          Company 2 33%

               Company 2 is owned by

                    John Doe 25%

                    Dave Smith 75%

     So... Company 1 is owned:

          Jane Doe 33%

          Dave Smith (75% of 33%) or 24.75%

          John Doe 33% + (25% of 33%) or  41.25%

     Now, any ideas on how to show on a layout or report the nested information?
