Allows replacement of nOpct in the legacy cancellation caller.

01 · OVERVIEW

Overview

P12.2210 records {nOpct} and assigns the result to nOpct in FA460ECAN. The GitHub copy places this call inside Begin Transaction, then compares nOpct with 1. This does not justify returning a logical validation flag. F460CANC is not named in the migration article’s removed-hook list; verify release availability. (Refs. 1–4) Research includes indexed TDN evidence; no complete specific page was recovered.

02 · SYNTAX

Syntax

User Function F460CANC()

Parameters

Entry point context

UnconfirmedContext to confirm

The complete technical contract remains unconfirmed. Do not assume types, PARAMIXB positions or aliases beyond the evidence described.

Return value

Result replaces nOpct; the copy compares it with numeric 1. Other options are not detailed.

03 · PRACTICAL EXAMPLE

Observed call and context

// Analysis of a legacy caller published on GitHub (ref. 3); not a hook implementation.
// Begin Transaction
// If ExistBlock("F460CANC")
//     nOpct := ExecBlock("F460CANC",.F.,.F.,{nOpct})
// EndIf
// If nOpct == 1 .Or. lOpcAuto2
//     // ...

Expected result

The record shows arguments and immediate return use where present. It omits the full caller body and does not establish commit timing.

BEST PRACTICES

The GitHub copy does not identify a validated release and is not an official distribution. Check the caller in the target environment; this example analyzes legacy flow rather than providing a deployable function.
A call without a fourth argument does not document a PARAMIXB layout. Preserve caller identifiers and do not invent fields or positions.
Test plan: compare standard and customized flows, exercise success, rejection and repetition, and inspect balances, movements and accounting as applicable.
Under review: example not compiled or run in Protheus. Verify aliases, locks, transaction position and compatibility in the target release and patch.
