You may have encountered this message when trying to remove a question:

Warning message: Cannot delete variables with dependents

Dependents can be found in different aspects of a survey, including variables, analyses or reports that depend on another variable. If a variable has dependents you cannot delete it until all the things that are dependent on it, its dependents, have been removed.

It is useful to know how to view the dependents. This identifies the dependencies that need to be removed before you can delete the variable.

A dependent can use a variable in:

  • routing
  • a derived variable
  • a label of a variable
  • an analysis variable
  • analyses or reports
