1.3.3.3 Date Derivation

Effective Date

If the Original Requested Effective Date is given and backdated, then the system defaults the Host date as the Instruction Date.

System checks the Requested Effective Date for network holidays, currency holidays (Debit). If the Effective date falls on Network / Currency holidays, the Effective Date moves forward to the Network Working date / Currency Working date.

During date derivation, the cutoff times for Same Day and Standard transactions maintained in US ACH Network Preferences (Function ID: PNDNWPRF) are validated. Based on these cutoff times and the preference for processing Same Day transactions as Standard ACH after the Same Day cutoff, both the settlement method and effective date are re-derived.

Date derivation for ACH Debit standard transactions considers the Dispatch Days (1 day) maintained in US ACH Network Preferences, ensuring that the derived dispatch date is at least 1 day earlier than the Effective Date.
