PROBLEM
The following error is thrown when running the report: #ERROR# The expression contains undefined function call MyUserFunction()

SOLUTION

This error can occur in any of these three cases:
  1. The class library has not been rebuilt and thus the function does not yet exist.
  2. Using the function with wrong number/type of parameters. The passed fields must match the function signature you've defined originally.
  3. A field specified as function argument is null. Make sure that such cases are handled in the user function.
