ACH Settlement Window Same Day Lookup
Select earliest still-open caller ACH same-day submission window and paired settlement clock, inclusive at cutoff; caller has already verified processing date/network eligibility/time zone, no hardcoded NACHA clock or settlement assurance.
Description
Same-day Automated Clearing House (ACH) window selection compares a local submission clock with verified cutoff/settlement pairs.
Same-day Automated Clearing House (ACH) window selection compares a local submission clock with verified cutoff/settlement pairs. A missed final window must remain explicit.1
The returned values include Selected caller window index, Selected caller settlement clock, Caller same day window available. The How section below explains the calculation, input rules and interpretation.
When to use ACH Settlement Window Same Day Lookup
Use ACH Settlement Window Same Day Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. Processing date, network eligibility and time zone are external; no universal NACHA clock or settlement assurance is supplied.
Prepare observed financial records and verified caller terms. Use one currency for integer minor-unit money and preserve leading zeros in identifier text. One basis point is 0.01 percentage points. Resolve dates, local clocks, counting rules and evidence flags as specified.
How to use ACH Settlement Window Same Day Lookup and understand its results
- Prepare observed financial records and verified caller terms. Use one currency for integer minor-unit money and preserve leading zeros in identifier text. One basis point is 0.01 percentage points. Resolve dates, local clocks, counting rules and evidence flags as specified.
- Enter submissionClock, callerSameDayCutoffClocks, callerCorrespondingSettlementClocks using the field table and calculation rules, then run the tool.
- Read selectedCallerWindowIndex, selectedCallerSettlementClock, callerSameDayWindowAvailable. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| submissionClock | Submission clock | string | Required |
| callerSameDayCutoffClocks | Caller same day cutoff clocks | list of string | Required |
| callerCorrespondingSettlementClocks | Caller corresponding settlement clocks | list of string | Required |
Enter exact HH:mm submission and aligned nonempty clock lists. Require strictly increasing cutoffs and settlements, with each settlement at least its corresponding cutoff. Equality at cutoff qualifies. Return zero-based first available window, paired settlement clock and availability; after the final cutoff return −1, empty string and false.
index=first cutoff≥submission; settlement=index≥0?pairedClock:emptyString Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| selectedCallerWindowIndex | Selected caller window index | number |
| selectedCallerSettlementClock | Selected caller settlement clock | string |
| callerSameDayWindowAvailable | Caller same day window available | boolean |

}Limitations and assumptions
Processing date, network eligibility and time zone are external; no universal NACHA clock or settlement assurance is supplied.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
Alternative or Complementary methods
Use SEPA Cutoff Deadline Lookup: A local bank cutoff and processing calendar jointly determine the modeled SEPA dates. Time zone and daylight-saving conversion must already be resolved. For a complementary task, use Stop Payment Duration Lookup: A stop-payment timing check uses an effective date and exclusive expiry. A positive days-remaining value before the start does not establish current validity.
