Call of subschemas/subsystems

The -SS Lines tab is common to the Table editor and Logical View editor. It is used to define the list of subschemas in a Logical View or the list of subschemas and subsystems in a Table (Pactables).

Figure 1. Example of a -SS Lines tab
-SS Lines tab
Line type
This field is dimmed. It automatically displays the type of line for the line selected in the list of subschemas and subsystems. A line containing a subschema is referenced as an S-type line, and a line containing a subsystem is identified by a 'Y' letter.
Number
Enter the number associated with the subschema or subsystem added to the list of -SS lines. You can create up to 10 subschemas or subsystems. Select a number from '0' to '9'; the value '0' corresponds to the number '10'. A value is mandatory in this field.
Subschema or subsystem name
A name associated with the subschema or subsystem selected in the list of -SS lines is mandatory in this field. This name is six characters long maximum. Use the standard labels in Pactables for a subsystem called in a Table.
Max number of occurrences
This field is used to indicate the repetitive read or update capacity of the server which calls a subschema or subsystem belonging to a repetitive structure (C/S). This capacity is expressed by a maximum number of repetitions. This value is automatically set to '100'. The field is dimmed when it corresponds to the amount of space reserved for a Segment in memory (Batch Applications function). For subsystems from Pactables, this field is strictly for documentation purposes.
Note: Data Elements and Segments are associated with subschemas in the -CE Lines tab of the Logical View editor, in a wizard you open by clicking More in the Data Element call, Segment call, or Group definition section.
