Rules and Guidelines for Expression Masking

Rules and Guidelines for Expression Masking

Use the following rules and guidelines for expression masking:
  • You cannot use the output from an expression as input to another expression. If you manually add the output port name to the expression, you might get unexpected results.
  • Use the point-and-click method to build expressions. Select functions, ports, variables, and operators from the point-and-click interface to minimize errors when you build expressions.
  • If the Data Masking transformation is configured for repeatable masking, and the storage table does not exist, the Integration Service substitutes the source data with default values.
