How much overhead is involved in creating new instances of tables in the relationship graph and using them in portals? The reason I'm asking is that I have a month display in which I want to use 31 separate portals. In the relationship graph I made 31 serperate instances of a particular table which are accessed by a table with a date and 30 unstored calcs that increment that date (eg. date1 = date + 1, date2 = date + 2). How does filemaker store the 31 instances of what is basically the same data in the graph? There wouldn't be 31 seperate copies of the same data stored in the file right?

To answer your question one would have to know the datails of a FM file. I would guess that 31 relationships are stored since each one is different. You could make a test of the file size with the 31 relationships vs the same file without them.

Hi,

Actually, you don't need either these 31 TO's nor the 31 calculations.

You'd only need 31 records with one unstored calculation on each record.
