InstdAmt must be strictly positive (> 0). The XSD allows 0, but it is commercially invalid.
Why pain.001 files fail rule PAIN00109-GEN-005 (ERROR) and how to fix it: InstdAmt must be strictly positive (> 0). The XSD allows 0, but it is commercially invalid.
What this rule checks
InstdAmt must be strictly positive (> 0). The XSD allows 0, but it is commercially invalid.
Affected element: CdtTrfTxInf/InstdAmt.
Applies to pain.001.001.09. Severity: ERROR.
Why your file is rejected
Banks validate this rule server-side after the XSD schema check. When it fails, the whole file is typically rejected — even if every other transaction is correct — so a single violation blocks the entire batch.
How to fix it
Ensure every CdtTrfTxInf/InstdAmt value is strictly greater than 0. Locate the offending element(s) and correct the amount or quantity.
