Rules and Guidelines for Field Expressions

Rules and Guidelines for Field Expressions

Certain rules and guidelines apply when you create a field expression.
Use the following rules and guidelines for field expressions:
  • If you do not specify the correct datatype, precision, or scale, the test produces an error.
  • The datatypes that you can select are PowerCenter transformation datatypes.
  • The precision and scale of the field expression must match the precision and scale used in PowerCenter for the specified datatype.
