Informix Error -4660: Report parameters cannot take object references.

Reasons / Common Causes

-4660 fires when a report's formal parameter is declared with a class name (or FOREIGN) as its data type — per the official guidance, this isn't supported.

1. A report parameter declared with a class name (or FOREIGN) as its type, per the official guidance — the direct, only cause.

Solutions / Resolution

1. Use a supported scalar/record type for report parameters instead of an object reference.

Examples

A report parameter declared with a class type

REPORT myreport(cust Customer)
-- -4660: report parameters can't take an object reference

Diagnostic Checks

1. Check every report's parameter list for a class-typed (or FOREIGN-typed) parameter, and replace it with a supported type.
