User-Defined Default Input Values

User-Defined Default Input Values

You can enter a user-defined default input value if you do not want the Integration Service to treat null values as NULL.
To override null values, complete one of the following tasks:
  • Replace the null value with a constant value or constant expression.
  • Skip the null value with an ERROR function.
  • Abort the mapping with the ABORT function.
The following table summarizes how the Integration Service handles null input for input and input/output ports:
Default Value
Default Value Type
Description
NULL (displays blank)
System
Integration Service passes NULL.
Constant or Constant expression
User-Defined
Integration Service replaces the null value with the value of the constant or constant expression.
ERROR
User-Defined
Integration Service treats this as a transformation error:
  • Increases the transformation error count by 1.
  • Skips the row, and writes the error message to the log file or row error log.
The Integration Service does not write rows to the reject file.
ABORT
User-Defined
The mapping aborts when the Integration Service encounters a null input value. The Integration Service does not increase the error count or write rows to the reject file.
