User Function F340GREST()

Complements movement writes during payable compensation reversal.

F340GRESTFINA340

01 · OVERVIEW

Overview

TDN places this hook in complementary SE5 writes during reversal. Its example checks FieldPos("E5_MSEXP") and clears that field; this does not establish that clearing it suits other installations. The P12.2210 listing records ExecBlock in FA340CAN without an explicit context argument. (Refs. 1–2)

02 · SYNTAX

Syntax

User Function F340GREST()

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

The page does not detail a return consumed by the caller.

03 · PRACTICAL EXAMPLE

Observed call and context

// P12.2210 caller excerpt (EURAI, ref. 2); not an entry point implementation.
// FINA340.PRX - FA340CAN() -> EXECBLOCK("F340GREST",.F.,.F.)

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

Before adapting the official clearing example, establish the field’s local meaning and caller-held locks. The documentary excerpt does not authorize writing outside that context.
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.
