Logical View Overview tab

The Overview tab displays the label in a read/write mode. It also displays information specific to the instance in a read-only mode and provides access to the other tabs of the instance.

Description of the tab

Three sections are not tabs. They are displayed in the Overview tab only: Alerts and Action Items, General information, and Generation parameters definition (on some entities).

All the other sections provide links to the corresponding editor tabs.

If information is displayed in a section, you can do one of the following actions:
  • Click the information if it is displayed as a link. You automatically switch to where the information is specified.
  • Click More to switch to the corresponding tab.

The sections of the tab

Alerts and Action Items
Any problem that is related to the current instance is displayed in this section as a link. If you click this link, you automatically switch to the Problems view, where the line that corresponds to the error is highlighted. The error is explained and you can correct it.
The General information section displays the following fields:
Work context
The work context is the project from which you open the editor of the current instance. This project constitutes the starting point for the resolution of the dynamic links and references between the instances of the various projects. The projects hierarchy that is declared in the design build path is explored in an upward direction.

If you click Hierarchy, you can see a partial view of the design build path. In this view, the project that constitutes the work context is the lowest project of the hierarchy.

For more information, see The work context and The design build path.

Name
The instance name is displayed in read-only mode. It is entered when the instance is created, and it cannot be modified later.
As a reminder, the name of a Segment, Logical View, or Table is constituted of two parts:
  • The first part is constituted of two alphanumeric characters that correspond to the associated Data Structure. If the Data Structure does not exist, it is automatically created in the project of the new Segment and it calls the Segment in its -LS Lines. If the Data Structure exists in a parent project in the hierarchy of the design build path, it is automatically duplicated in the project of the new Segment and it calls the Segment in its -LS Lines. If the Data Structure exists in a child project in the hierarchy of the design build path, it is not modified in this project and is created in the project of the new Segment. It calls the Segment in its -LS Lines in the project of the new Segment.
  • The second part is constituted of two characters that correspond to the record code. The coding rules depend on the Segment type:
    • For Segments, the first character must be numeric. The second character can be numeric or alphabetic. It can be alphabetic only if the first character is other than zero. You can enter the following values for the record code:
      • 00: This code represents the common part of the records in a file or a database. By default, it is located at the beginning of each record. The control break sort keys, the record type, and the keys of indexed files must belong to this Segment. A file does not necessarily have a common part. A file that contains only one type of record must be declared as a Segment 00.
      • 01 – 99, 1A – 9Z: This code represents the specific part of the records. The Data Elements of the common part are automatically concatenated with the Data Elements of each Segment from the specific part.
    • For Logical Views, the first character must be numeric. The second character can be numeric or alphabetic. It can be alphabetic only if the first character is other than zero.
    • For Tables, the two characters of the record code must be numeric, from 01 to 99.
Label
Enter the label that identifies the instance. It will constitute a search criterion upon a subsequent search.
Definition
This section displays the Number of occurrences and Transfer direction values in a read-only mode. The definition can be modified or completed in the Definition tab. Click More to switch to this tab and find the data-entry fields.
The other sections of the Overview tab display the information, if any, entered in the corresponding tabs:
  • The Keywords section displays the Logical View keywords.
  • The -CE Lines section displays the Data Elements and Segments called in the Logical View.
  • The -SS Lines section displays the list of subschemas and subsystems associated with the Logical View.
  • The Level, Address and Length section displays information about the elements called in the Logical View such as their COBOL descriptions and statistics in a read-only mode.
  • The -G Lines section displays the comments, error messages, generation elements, generation options associated with the Logical View.

Clicking More in each section switches to the corresponding tab, where updates are possible.
