01 · OVERVIEW

Overview

The TOTVS index leaves this item under construction. P12.2210 records FA590CANC calls with {"P",cNumBor} and {"R",cNumBor}, without assigning the result. This documents two observed arguments but does not establish exact cancellation or transaction timing. No useful GitHub implementation was located. (Refs. 1–2) Research includes indexed TDN evidence; no complete specific page was recovered.

03 · PRACTICAL EXAMPLE

Observed call and context

// P12.2210 caller excerpt (EURAI, ref. 2); not an entry point implementation.
// FINA590.PRX - FA590CANC() -> EXECBLOCK("F590CAN",.F.,.F.,{"P",CNUMBOR})
// FINA590.PRX - FA590CANC() -> EXECBLOCK("F590CAN",.F.,.F.,{"R",CNUMBOR})

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 P and R literals are preserved as they appear in the source; their complete meaning is unconfirmed. Do not confuse this hook with neighboring identifiers or assume SE1 or SE2 is positioned.
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.
