Parameter is not referenced

Properties
LC0095 Warning Design Code Fix Ignore Obsolete

CodeCop AA0137 detects unreferenced parameters only in local procedures and explicitly excludes event subscribers. LC0095 covers the non-local, non-subscriber gaps: internal procedures and public procedures.

A parameter that is never referenced in the procedure body clutters the signature, misleads callers about what the procedure needs, and creates unnecessary coupling. Removing it simplifies both the definition and every call site.

Example

codeunit 50100 MyCodeunit
{
    procedure MyProcedure(MyVariant: Variant) // Parameter 'MyVariant' is not referenced in procedure 'MyProcedure'. [LC0095]
    begin
    end;
}

Fixed:

codeunit 50100 MyCodeunit
{
    procedure MyProcedure()
    begin
    end;
}

Covered by this rule

  • Internal procedures
  • Public procedures

Excluded from this rule

  • Local procedures (AA0137 handles them)
  • Triggers (platform-defined signatures, cannot be changed)
  • Interface implementations (bound by interface contract)
  • Event declarations ([IntegrationEvent]/[BusinessEvent], parameters define the subscriber contract)
  • Obsolete procedures (pending or removed, not worth modifying)
