Adding Computed Fields (COMPUTE) in a Synonym
You may create a Computed field as a custom field in
the Synonym Editor. The procedure for adding a custom field is similar
to the procedure used to add a Defined field. The Computed field
is identified as the Master File Computed field and is differentiated from
the Defined fields and the other Computed fields.
Note: Computed fields from the
Master File appear in the Report Painter fields list.
