DisarmTransaction
DisarmTransaction()Requests rollback and puts the transaction in TTSBREAK.
Overview
DisarmTransaction affects the protected work since the first BEGIN TRANSACTION, including nested levels. After the call, flow must leave through BREAK past the appropriate END TRANSACTION or terminate the thread; a new transaction cannot start while TTSBREAK remains. TOTVS prohibits BeginTran/EndTran for Protheus transaction control. The fragment illustrates failure in its own block without real writes. Do not insert it into a borrowed transaction without understanding outer levels. (TOTVS, n.d., ref. 1)
