How do we test refunds and chargebacks in ERP finance module for mutual fund SIPs under the new UPI cap structure?

Integrate the ERP finance module with the PSP/NPCI UPI limit-eligibility API and tag each payment as EVENT_TICKETING before the check.

If the API returns higher-limit support for the customer’s bank, show a banner like Your bank supports higher UPI limits for ticket purchases,  up to ₹X available.

Cache eligibility results per bank for a few hours and fall back to standard-limit messaging when no enhanced limit is returned.

Maintain a category→limit table for UTILITY_PAYMENTS (per-txn + daily caps) and tag each payment with that category before intent creation.

Pre-validate: reject or auto-split if amount > perTxnLimit and check (today_inflow_for_category + amount) ≤ dailyAggregateLimit per VPA/merchant.

Call PSP/NPCI eligibility APIs for bank-specific overrides when available, then record RRNs and update daily counters after settlement for audit and reconciliation.

Maintain a category-limit matrix defining UPI caps for “Vehicle Down Payments” per NPCI and bank rules. Pre-validate each payment against per-transaction and daily caps before initiating the UPI intent. Call PSP/NPCI APIs for real-time bank-specific limit eligibility when available. Handle exceedances by auto-splitting payments or suggesting fallback methods like RTGS or NetBanking.

• Pre-check UPI cap: Before payment initiation, verify each SIP installment against the investor’s per-transaction UPI limit using the PSP or NPCI cap API.
• Auto-split logic: If the amount exceeds the cap, divide it into smaller tranches (e.g., INR 95,000 each) under the same SIP mandate ID.
• Sequential processing: Trigger the next UPI request only after confirmation of the previous one to prevent duplication.
• Unified reconciliation: Link all split RRNs under one SIP reference for settlement and audit tracking.

Maintain a category→limit table (e.g., GEM) with per-txn and daily aggregate caps, plus bank/PSP overrides, and tag every purchase with its category and payer VPA.

Pre-validate: before creating the UPI intent check amount ≤ perTxnLimit and (today_inflow + amount) ≤ dailyLimit; call PSP/NPCI eligibility API for bank-specific allowance when available.

If limits are exceeded, auto-split or block and show fallbacks (NetBanking/card); after settlement record RRNs and update daily counters for reconciliation and audit.
