The MT 422 is sent in response to a tracer.
The MT 422 may be a single or a multiple message. When it is a multiple message, it must refer to one collection (for at least one of the banks) or one collection message.
When one of the banks views a collection with more than one item as more than one collection, fields 20 and 21 are to be used as follows:
The remitting bank sends what it considers to be two separate collections (references '1' and '2') to the collecting bank.
The collecting bank, when sending an acknowledgement, considers this to be one item (reference 'A')
Fields 20 and 21, will appear as:
 1st repetitive sequence: |
:20:A |
| |
:21:1 |
| 2nd repetitive sequence: |
:20:A |
| |
:21:2 |
The remitting bank sends what it considers to be one collection (reference '1') to the collecting bank.
The collecting bank, when sending an acknowledgement, considers this to be two items (reference 'A' and 'B').
Fields 20 and 21 will appear as:
| 1st repetitive sequence: |
:20:A |
| |
:21:1 |
| 2nd repetitive sequence: |
:20:B |
| |
:21:1 |
One MT 422 may be sent for several amounts of a collection when they refer to the same queries or answers.
