User-Defined Default Output Values

User-Defined Default Output Values

You can create user-defined default values to override the system default values for output ports.
You can enter user-defined default values for output ports if you do not want the Integration Service to skip rows with errors or if you want the Integration Service to write a specific message with the skipped row to the log. You can enter default values to complete the following functions when the Integration Service encounters output transformation errors:
  • Replace the error with a constant value or constant expression. The Integration Service does not skip the row.
  • Abort the mapping with the ABORT function.
  • Write specific messages in the log for transformation errors.
You cannot enter user-defined default output values for input/output ports.
The following table summarizes how the Integration Service handles output port transformation errors and default values in transformations:
Default Value
Default Value Type
Description
Transformation Error
System
When a transformation error occurs and you did not override the default value, the Integration Service performs the following tasks:
  • Increases the transformation error count by 1.
  • Skips the row, and writes the error and input row to the session log file or row error log, depending on session configuration.
The Integration Service does not write the row to the reject file.
Constant or Constant Expression
User-Defined
Integration Service replaces the error with the default value.
The Integration Service does not increase the error count or write a message to the log.
ABORT
User-Defined
Mapping aborts and the Integration Service writes a message to the log.
The Integration Service does not increase the error count or write rows to the reject file.
