Is there an easy way to recreate the relationship tables in FileMaker for a SQL Data Source that already exists or does this need to be done manually?
Every external table (for which you have permission and desire to use) must be placed on the graph. If you want relationships, then you must manually create them between any two Table Occurrences (graphical representations of the tables), including between FM and any other source that can be added to the graph.
(get the pdf on this page from the "Introduction to External SQL Sources" link)
if you have the sql data source defined you just need to add TO's from the data source to the relationship graph
