TRICKYpacs.002In pacs.002, what does GrpHdr/CreDtTm (Creation date and time) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in Base ISO 20022 message definition.
WHY IT MATTERS
When this report was created. Several reports about the same payment can arrive as its status evolves — order matters. Pitfall: Processing status reports out of order can overwrite a final status with an earlier interim one.

MODEL ANSWERDIRECT ANSWER
MANDATORY in Base ISO 20022 message definition.

SWIFT & MT
TRICKYMT101In MT101, what does :20: (Sender's Reference (sequence A)) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
The sender's own reference for the whole request — the number quoted in any later query about it. One reference covers the full message, which may contain many transactions; individual transactions are identified by field 21 in each sequence B. Pitfall: Reusing references defeats duplicate detection and muddies investigation trails.
TRICKYMT101In MT101, what does :28D: (Message Index / Total (sequence A)) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
Says which message this is in a set, such as 1 of 3, when a large request is split across several MT101s. All messages in a chained set share the sender's reference and must arrive as a complete set before execution. Pitfall: Broken chaining — a missing index or inconsistent totals — leaves the executing bank with a partial batch it cannot safely process.
MEDIUMMT192In MT192, what does :20: (Transaction reference number) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY. Unique reference for the cancellation request itself.
MEDIUMMT192In MT192, what does :21: (Related reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY. Quotes field 20 of the original payment being cancelled.
MEDIUMMT195In MT195, what does :20: (Query reference) mean, and what can go wrong?
MEDIUMMT195In MT195, what does :21: (Related reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY. Reference of the original message being queried.
MEDIUMMT196In MT196, what does :20: (Answer reference) mean, and what can go wrong?
MEDIUMMT196In MT196, what does :21: (Related reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY. Reference of the MT192 or MT195 being answered.
MEDIUMMT199In MT199, what does :20: (Transaction reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY. Unique reference for this free-format message or case.
MEDIUMMT199In MT199, what does :21: (Related reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY. Reference of the payment or request being discussed.
MEDIUMMT202 COVIn MT202 COV, what does :20: (Transaction Reference Number (sequence A)) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
The sender's unique reference for the cover transfer. Distinct from the underlying MT103's reference — the linkage happens through field 21 and the shared UETR.
TRICKYMT202 COVIn MT202 COV, what does :21: (Related Reference (sequence A)) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
Links the cover to the underlying customer payment. Market practice is to quote the sender's reference (field 20) of the underlying MT103 here, so the beneficiary bank can match cover to announcement. Pitfall: An unmatchable related reference leaves the customer payment waiting for funds that have in fact arrived.
MEDIUMMT202In MT202, what does :20: (Transaction Reference Number) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
The sender's unique reference for this transfer. Adjacent banks reconcile and query on this reference; end-to-end tracking uses the UETR in the header.
TRICKYMT202In MT202, what does :21: (Related Reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
Points at the business event this transfer settles — a deal reference, a related payment, or NONREF when nothing applies. Receiving banks auto-match incoming cover and settlement credits on this field. A meaningful related reference is the difference between straight-through reconciliation and an investigation. Pitfall: Defaulting to NONREF when a real reference exists pushes the receiver into manual matching.
MEDIUMMT900In MT900, what does :20: (Transaction reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY. Reference assigned to this debit confirmation.
MEDIUMMT900In MT900, what does :21: (Related reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY. Reference of the payment or instruction that produced the debit.
MEDIUMMT910In MT910, what does :20: (Transaction Reference Number) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
The sender's unique reference for this confirmation. References the advice itself, not the payment that caused the credit — that link lives in field 21.
TRICKYMT910In MT910, what does :21: (Related Reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
The reference of the transaction that produced the credit, as known to the sender. This is what the account owner's reconciliation matches against expected receipts. Its usefulness depends entirely on what reference the crediting transaction carried. Pitfall: If the underlying payment's reference was lost or replaced along the chain, the advice arrives but nothing matches.
MEDIUMMT940In MT940, what does :20: (Transaction Reference Number) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
The sender's unique reference for this statement message. Identifies the message, not the account or period — those live in fields 25a and 28C.
TRICKYMT940In MT940, what does :21: (Related Reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
OPTIONAL in SWIFT Standards MT.
WHY IT MATTERS
Links the statement to a request, when it was produced in answer to one. Used when the statement responds to an MT920 request; routine scheduled statements omit it.
MEDIUMMT941In MT941, what does :20: (Transaction reference) mean, and what can go wrong?
MEDIUMMT941In MT941, what does :21: (Related reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY. Reference to the request or service event where applicable.
MEDIUMMT942In MT942, what does :20: (Transaction reference) mean, and what can go wrong?
MEDIUMMT942In MT942, what does :25: (Account identification) mean, and what can go wrong?
MEDIUMMT950In MT950, what does :20: (Transaction reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY. Reference assigned to the statement message.
MEDIUMMT950In MT950, what does :25: (Account identification) mean, and what can go wrong?
Payments foundations
TRICKYMT103In MT103, what does :20: (Sender's Reference) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
The sender's own reference for this payment — the number everyone quotes when questions come up later. It anchors queries, cancellations, and reconciliation between adjacent banks; end-to-end tracking across the whole chain relies on the UETR in the header instead. Pitfall: Reused references break duplicate detection and confuse investigations.
MEDIUMMT103In MT103, what does :23B: (Bank Operation Code) mean, and what can go wrong?
MODEL ANSWERDIRECT ANSWER
MANDATORY in SWIFT Standards MT.
WHY IT MATTERS
Tells the receiving bank what kind of transfer this is; CRED marks an ordinary credit transfer. CRED is the everyday value. Other codes are rare, tied to specific service arrangements, and some legacy values have been withdrawn over successive standards releases.
