Here are some points to take away regarding user-defined fields and tables:
• You can add user-defined fields to most objects, at either the header level or
the row level.
• User-defined fields are added to the table for the selected object, and have
prefix “U_”.
• User-defined fields added at the header level will show in a separate window to
the side of the document. You can use the View menu to open this window.
• You can manage multiple user-defined fields at the header level using the
settings window. This allows you to assign categories, set fields as invisible,
and reorder the sequence.
• User-defined fields can have various types and structures, such as
alphanumeric and regular. The choice of structure affects the maximum field
length and the type of data you can enter in the field.
• You can optionally add a list of valid values to a UDF, or set a default value, or
make the UDF mandatory
• You can create user-defined tables to the database. These tables can hold
additional, related information. User-defined tables can be identified with the
prefix “@”.
• To make a user table available in a document or form, link the table to a UDF in
