Update.AxdEntity_CustTable[] AxCustTableData = new Update.AxdEntity_CustTable[1];

Update.CallContext AxDocumentContext = new Update.CallContext();

AxDocumentContext.Company = “CEU”;

Update.EntityKey[] entityKeyList = new Update.EntityKey[1];

Update.EntityKey entityKey = new Update.EntityKey();

Update.KeyField[] keyDataList = new Update.KeyField[1];

Update.KeyField keyField = new Update.KeyField();

keyField.Field = “AccountNum”;

keyField.Value = “1103”;

entityKeyList[0] = entityKey;

AxCustTableData[0] = new Update.AxdEntity_CustTable();
