Create Frame MD3

To create a frame, perform the following actions:

  1. In Navigator section Frames right-click and select New Frame. An empty frame is displayed with 3 rows.
  2. In Inspector tab Specification type a unique name for the frame.
  3. Create the desired number of rows by adding or deleting them.
  4. Fill each row with a variable or aggregate frame.
  5. A primary key is mandatory. The integrity checker guards this. In its simplest form one variable is primary key. Do the next actions.
    1. In Inspector tab Specification right-click section Foreign key.
    2. Select Add Variable to Primary Key. A list with the variables in the frame appears.
    3. Select one variable.
    4. Double-click it, or click button Insert Variable.

This results in the most simple form of a primary key. Adding more variables results in a "composite" primary key. Also aggregate frames can be (part of) the primary key. See the next link.
