Explanation

Generated from the read-only evidence below. It never changes a match or a record.

LLM · openai/gpt-oss-120b

The bank credit can be explained by more than one combination of settlements, making the batch ambiguous.

The engine found two distinct settlement sets that together sum to the bank line amount of ₹1,96,939.36. Both sets contain the same large settlement (setl_LWCAItDAeKt7mb) and differ only in one smaller settlement, leading to a tie in the ranking criteria. Because uniqueness is not established, the system cannot automatically pick one set.

Recommended action

Consult the gateway payout report and manually confirm which settlement combination matches the bank credit, then mark the correct set as matched.
