ERROR Functions in Output Port Expressions

ERROR Functions in Output Port Expressions

If you enter an expression that uses the ERROR function, the user-defined default value for the output port might override the ERROR function in the expression.
For example, you enter the following expression that instructs the Integration Service to use the value ‘Negative Sale’ when it encounters an error:
IIF( TOTAL_SALES>0, TOTAL_SALES, ERROR ('Negative Sale'))
The following examples show how user-defined default values may override the ERROR function in the expression:
  • Constant value or expression.
    The constant value or expression overrides the ERROR function in the output port expression.
    For example, if you enter ‘0’ as the default value, the Integration Service overrides the ERROR function in the output port expression. It passes the value 0 when it encounters an error. It does not skip the row or write ‘Negative Sale’ in the log.
  • ABORT.
    The ABORT function overrides the ERROR function in the output port expression.
    If you use the ABORT function as the default value, the Integration Service aborts the when a transformation error occurs. The ABORT function overrides the ERROR function in the output port expression.
  • ERROR.
    If you use the ERROR function as the default value, the Integration Service includes the following information in the log:
    • Error message from the default value
    • Error message indicated in the ERROR function in the output port expression
    • Skipped row
      For example, you can override the default value with the following ERROR function:
      ERROR('No default value')
      The Integration Service skips the row, and includes both error messages in the log.
