None of the 108 values it checks in transactions initiated can be negative (Y 08.01, EBA rule v09225_s)

A warning in the payment fraud return (PSD2 fraud reporting), on template Y 08.01, transactions initiated by payment initiation services providers.

Check your file against this ruleWhat to do if it fails

The rule in plain words

None of the values it checks in transactions initiated can be negative.

EBA checks it for two columns: payment transactions and fraudulent payment transactions. And for nine rows, from payment transactions initiated by payment initiation service providers (0010) to other (0100). And on six sheets: domestic amount of payment, domestic number of transactions, cross-border within the EEA amount of payments, cross-border within the EEA number of transactions, cross-border outside the EEA amount of payments and cross-border outside the EEA number of transactions. That makes 108 checks. A failure names the one that failed.

How the Line4 Check report words itShow

The first of its checks, word for word as the report shows it when it fails. The others read the same, with their own column, row or sheet.

Payment transactions: Payment transactions initiated by payment initiation service providers, Domestic number of transactions >= 0

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Look for a value with the wrong sign in these cells, such as an amount entered as a negative number.
  3. 03EBA compares the values exactly here: there is no rounding tolerance.
  4. 04It runs only when your filing indicators mark Y 08.01 as reported.
  5. 05This is a warning. It does not stop the filing on its own, but your authority may ask you to explain it.

A worked example

The first of its checks, with simple numbers.

What the rule then expects

Payment transactions initiated by payment initiation service providers, payment transactions must then be at least 0.

0Passes
-100Fails

A file that reports 0 passes. One that reports -100 fails, by 100.

The numbers are illustrative.

EBA's formula, as written out for the first of its checks. Cells are written as {template, row, column, sheet}.

{Y_08.01,r0010,c0010,s0020} >= 0

The next five:

{Y_08.01,r0040,c0020,s0040} >= 0{Y_08.01,r0010,c0010,s0060} >= 0{Y_08.01,r0050,c0020,s0060} >= 0{Y_08.01,r0030,c0010,s0040} >= 0{Y_08.01,r0040,c0020,s0020} >= 0

And 102 more, the same formula for the other cells it covers.
