Ordering Customer Address - Inward Transfers

Tag 50 in MT103 can be :

50A - Ordering Customer (BIC format)
50F - Ordering Customer (structured format)
50K - Ordering Customer (account, name, and address format)

Format
Option A [/34x] (Account)
4!a2!a2!c[3!c] (Identifier Code)
Option F 35x (Party Identifier)
4*35x (Name and Address)
Option K [/34x] (Account)
4*35x (Name and Address)

In option F, the following line formats must be used (Error code(s): T54):
Line 1 (subfield Party Identifier) /34x (Account)
Lines 2-5 (subfield Name and Address) 1!n/33x (Number)(Details)
Or
Line 1 (subfield Party Identifier) 4!a/2!a/27x (Code)(Country Code)(Identifier)
Lines 2-5 (subfield Name and Address) 1!n/33x (Number)(Details)

So even option F might be not so easy.
With option K you can only check if something is passed.
Normally the name will be in second field, but the rest is undefined.
