SWIFT MT field format rules

Can someone point me to a document where the formatting rules for a MT message field are described?

For example I want to know what the following snippet means.

:4!c//3!a/3!a/15d

Solution

  • This is described in the MT 'General Information' documentation. You can find the 2017 edition of this document here. Specifically, check out section 6.1 for an explanation.

    How to read :4!c//3!a/3!a/15d:

    • first :
    • then 4 mandatory c
    • then //
    • then 3 mandatory a
    • then /
    • then 3 mandatory a
    • then /
    • then maximum 15 d

    A brief overview of the character types in regex:

    • c is [A-Z0-9]
    • a is [A-Z]
    • d is \d+,\d*
