F590IMPOST call whose result feeds lContabil.

F590CTBFINA590

01 · OVERVIEW

Overview

The official index does not detail the contract. P12.2210 records lContabil := ExecBlock("F590CTB",.F.,.F.) in F590IMPOST. This confirms immediate result use without explicit context but does not document all accounting effects or transaction position. No useful GitHub implementation was found. (Refs. 1–2) Research includes indexed TDN evidence; no complete specific page was recovered.

02 · SYNTAX

Syntax

User Function F590CTB()

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

Assigned to lContabil; accounting policy and default value unconfirmed.

03 · PRACTICAL EXAMPLE

Observed call and context

// P12.2210 caller excerpt (EURAI, ref. 2); not an entry point implementation.
// FINA590.PRX - F590IMPOST() -> LCONTABIL := EXECBLOCK("F590CTB",.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

Do not use Return .F. as a neutral example: it can change accounting. Inspect F590IMPOST, accounting entries and reversals in the target release.
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.
