Error

FX-SCH-A-000462: Add the format attribute to the invoice period start date

In short

Error: fails the selected checks.

FX-SCH-A-000462 means the invoice period start date (BT-73) is missing the format attribute on udt:DateTimeString. Add the attribute to that element. For a date written as YYYYMMDD, use format 102.

What it means

Within the invoice period (BG-14), this rule checks for a format attribute on ram:BillingSpecifiedPeriod/ram:StartDateTime/udt:DateTimeString under ram:ApplicableHeaderTradeSettlement. It checks presence only: an empty attribute exists and therefore passes this test. It does not check the format code or date text. FX-SCH-A-000460 covers the end date.

Why it matters

The format attribute declares how the date text is encoded.

How to fix it

Correct the start date's XML representation rather than removing a period that belongs on the invoice. Add format to the affected udt:DateTimeString and make its value match the date text. If you use 102, write the date as YYYYMMDD. Have your software's export corrected if necessary, then export and recheck the invoice.
