Create external bank account using "fscmRestApi/resources/11.13.18.05/externalBankAccounts"

Dear All,

I am attempting to create an external bank account using the following endpoint: fscmRestApi/resources/11.13.18.05/externalBankAccount.

This endpoint functions correctly when I provide values for BankName and BankBranchName. An example of the request payload is as follows:

{
"CountryCode": "CH",
"BankAccountNumber": "XXXXX",
"CurrencyCode": "CHF",
"BankName": "BankName,
"BankBranchName": "BankBranchName",
"IBAN": "XXXXX",
"Intent": "Person",
"PayeeCreation": "Y",
"PersonId": "3000000043703645",
"accountOwners": [
{
"AccountOwnerPartyIdentifier": "3000000041623015",
"PersonId": "3000000043703645",
"Intent": "Person"
}
]
}

However, when attempting to use BankNumber and BankBranchNumber instead of BankName and BankBranchName, the API does not function correctly. An example of the request payload in this case is as follows:

{
"CountryCode": "CH",
"BankAccountNumber": "XXXX",
"CurrencyCode": "CHF",
"BankNumber": "BankNumber",
