The Table entity

A Table is a set of several occurrences of a Segment. It must belong to a Data Structure. A Table, described only once, can be called into any entity that uses Tables (Programs, Segments, Tables, Database Blocks). It is a set of Data Elements that are grouped because they are related to the same topic. Many of its characteristics are similar to those of the Segment.

-CE lines

A Table is described in the -CE Lines tab of the Table editor. In a Table, different Data Elements are called: the key Data Element, the information Data Elements, the Data Element specifying the subsystems, and the technological Data Elements.
Restriction: The Data Elements used in the description of a Table must be defined with a usage set to display (in the Usage field of the Data Element Definition tab). The maximum length allowed for a Table is 999 characters. The length of the data file is variable. The maximum length for a table key is 20 characters. The maximum number of Data Elements called in a Table is 40

-SS lines

The subschemas and subsystems of a Table are defined on the -SS Lines tab of a Table. It is possible to define 10 subsystems and 10 subschemas per Table. The subsystems are referenced by numbers from 1 to 0 (the value 0 identifies subsystem 10). The same principle is used for the subschemas. Each subschema and subsystem must be given a clear name.
