General Rules for Default Values

General Rules for Default Values

Use the following rules and guidelines when you create default values:
  • The default value must be either a NULL, a constant value, a constant expression, an ERROR function, or an ABORT function.
  • For input/output ports, the Integration Service uses default values to handle null input values. The output default value of input/output ports is always ERROR(‘Transformation Error’).
  • Variable ports do not use default values.
  • You can assign default values to group by ports in the Aggregator and Rank transformations.
  • Not all port types in all transformations allow user-defined default values. If a port does not allow user-defined default values, the default value field is disabled.
  • Not all transformations allow user-defined default values.
  • If a transformation is not connected to the mapping data flow, the Integration Service ignores user-defined default values.
  • If any input port is unconnected, its value is assumed to be NULL and the Integration Service uses the default value for that input port.
  • If an input port default value contains the ABORT function and the input value is NULL, the Integration Service immediately stops the mapping. Use the ABORT function as a default value to restrict null input values. The first null value in an input port stops the mapping
  • If an output port default value contains the ABORT function and any transformation error occurs for that port, the mapping immediately stops. Use the ABORT function as a default value to enforce strict rules for transformation errors. The first transformation error for this port stops the mapping
  • The ABORT function, constant values, and constant expressions override ERROR functions configured in output port expressions.
