Inputs (Array[] of CorrectionBusinessTransaction)

Two minor notes:

When creating a CorrectBusinessTransactionRequest you also need to attach CorrectionBusinessTransactionFields.
It doesn't have any properties and thus not holding any data, but is still needed in the request.
The CorrectionBusinessTransaction is not a special transaction type, but simply a wrapper that incapsulates SuperTransaction Ids.

Name	Type	Description	Mandatory	Available from version
BrickId	Guid	Ids of SuperTransactions to be corrected	Yes	2,14

Outputs

Name	Type	Description	Available from version
Entities	Array	Entites containing the BrickId (unique id) of the SuperTransactions

Code examples

 public static void CorrectBusinessTransaction()
        {
            var binding = new BasicHttpBinding();
            binding.MaxReceivedMessageSize = Int32.MaxValue;

            var target = new bfsapi.bfsapiSoapClient(binding, new EndpointAddress("http://localhost:20010/bfsapi.asmx"));
            var req = new bfsapi.CorrectBusinessTransactionRequest();
            req.Credentials = new bfsapi.Credentials
            {
                UserName = "username",
                Password = "password"
            };

            req.identify = "identity";
            req.Fields = new CorrectionBusinessTransactionFields();

            req.Entities=new CorrectionBusinessTransaction[]
            {
                new CorrectionBusinessTransaction
                {
                    BrickId = new Guid("e14ee5c1-cc78-4dad-bf0a-14800538a107")
                }, 
            };
            var resp= target.CorrectBusinessTransactions(req);
           

        }
