Informix Error -1351: The function (or report) name has already been defined. Function and report cannot both have the same name.

Reasons / Common Causes

-1351 fires when a function and a report (or two functions, or two reports) in the same program share a name — per the official guidance, each function or report must have a unique name throughout the program.

1. A function and a report defined with the same name, per the official guidance — the direct, named cause.
2. A name accidentally reused across separate source modules in a multimodule program, where the collision isn't obvious from any single file.

Solutions / Resolution

1. Rename either the current definition or the previously declared one, per the official guidance, to eliminate the duplicate.

Examples

A function and report sharing a name

FUNCTION order_summary()
  ...
END FUNCTION

REPORT order_summary(p_order_id)
  ...
END REPORT
-- -1351: order_summary is defined as both a function and a report

Corrected

FUNCTION order_summary()
  ...
END FUNCTION

REPORT order_summary_report(p_order_id)
  ...
END REPORT

Diagnostic Checks

1. Search the entire program (across all modules) for every function and report name, and confirm none collide.
