Error messages are automatically generated from the standard
controls that are completed when a Screen calls a Segment or a Data
Element. However, you can override these automatic messages, or declare
explicit messages for errors that are described in specific code.
Automatic error messages
Automatic error
messages correspond to the controls that are specified on the Screen -CE
Lines and to each file access.
Error messages are
divided into two parts:
- A message that corresponds to the error type and therefore to
the control or file access type. These standard error messages are
stored in one of the system files. However, they can be modified on-site
by the administrator.
- The Segment or Data Element label, except for the Segments that
are used in display.
Four standard error messages for validations on Data Elements
are generated:
- INVALID ABSENCE FOR THE FIELD
- INVALID PRESENCE FOR THE FIELD
- NON-NUMERICAL/NON-ALPHABETICAL CLASS FIELD
- INVALID VALUE FOR THE FIELD
The following standard file access error messages are
automatically generated for Segments:
- Segments that are used for input:
- INVALID CREATION RECORD
- INVALID MODIFY/DELETE RECORD
Both messages include the Segment .
- Segments that are used for display:
These automatically generated error messages can be customized
to your needs in the
-GE Lines section of the
-G
Lines tab.
Explicit error messages
Only the controls
that are entered on the Screen -CE Lines and
file accesses trigger the automatic generation of error messages.
For
other error types that are detected through other controls, error
messages must be explicitly entered. To do so, open the -GE
Lines section of the -G Lines in
the Screen or Dialog, depending on the type of error.
