Is it possible to create a "view" on a file maker table?

Not really a view as in SQL.

you can create a model and filter it to show only 1 or 2.

you can also consider the table occurences in the relationship tab as kind of view...  so you could have a globals table with a field only containing value 1 and link your table to it saying 1 = 1

but when you do a model using this table occurence, you must use it in relationship with the global table, like globals is source table for the model and your table is a portal.

Often in Filemaker, we simply perform a find to filter down the records in a table to just a specified sub set. You can script this and even use a layout based script trigger to make the filtering automatic if you so desire.

Filtered portals are another option we use in some such cases.
