Fields with global storage and summary fields cannot be used as key fields. A join table, Enrollments, creates two one-to-many relationships—one between each of the two tables. Existing data is deleted. Changing a field type changes the kind of data the field can contain. These foreign key fields are populated with data as records in the join table are created from either table it joins.

Fields in which indexing is disabled cannot be used as key fields. Using this design, if a student registers for three classes, that student will have one record in the Students table and three records in the Enrollments table—one record for each class the student enrolled in. Create a relationship between the two Student ID fields in the tables.

To avoid this problem, you can break the many-to-many relationship into two one-to-many relationships by using a third table, called a join table. Design the portal to show related records from the Classes table.
Look in the downloads of FM for the correct xbit driver. Planning a relational database.
With the database open in Browse modeclick Table View in the layout bar. For example, if you change a date field to a text field, you can type other information in the field besides a date, but you will no longer be able to sort chronologically. Consider the example of keeping track of invoices.

This is one reason for assigning a unique value to each invoice. Change the field options as needed.
Creating and changing relationships. It also affects how you find and sort information that uses that field. I have a client with FileMaker Pro 11 Advanced. Working with related data in portals.

The primary seuqel Class ID uniquely identifies each class in the Classes table. Date and time fields can’t contain text. The primary key Student ID uniquely identifies each student in the Students table.
These foreign key fields are populated with data as records in the join table are created from either table it joins. Relational database systems usually don’t allow you to implement a direct many-to-many relationship between two tables. You can add fields to the Enrollments table, such as a Date field to keep track of when someone started a class, and a Cost field to track how much a student paid dilemaker take a class.
