2.3.9 Early Nostro / Vostro Posting

A configurable option has been introduced to enable early posting of the debit leg immediately after booking for Generic Wires ISO transactions; the default behaviour remains unchanged unless this option is enabled.

Two new flags, Early Nostro Entry Posting and Early Vostro Entry Posting (Yes/No; default: No) have been added to the Generic Wires ISO Inbound Network Preferences (PSDIGWNP) screen.

When enabled, debit entries (SIDR) are posted and the accounting handoff is initiated immediately after booking, prior to Non-STP Rule evaluation; processing then continues as usual.

For Vostro accounts, an ECA check is performed with the DDA system. Debit posting and the handoff proceed only upon a successful ECA response.

If a cancellation occurs after an early debit has been posted, only a credit entry (SICR) is posted to the Return GL to offset the initial debit.

Scope: Applies to SWIFT CBPRPlus, RTGS ISO FI-to-FI Customer Credit Transfer (pacs.008) and FI Credit Transfer (pacs.009) Inbound and Pass-through transactions.
